  • Page 43: Hints For Programming Parts

    Hints for Programming Parts This manual does not describe any drawing functions in detail. However, the following information will give you an overview of basic programming procedures. Cursor With the mouse you move the cursor over the screen. Depending on the actual position of the mouse and on the command which has been chosen, the cursor will appear in different shape, either as a white arrow, as an I-beam or as a purple crosshair, etc.
  • Page 44 The right mouse button will bring up the context menu associated with the window or the objects being selected. Object Selection Functions The object selection functions allow you to choose objects by clicking the left mouse button on a drawing element or by clicking and dragging a selection window.
  • Page 45 selected. Selected objects are displayed with dashed lines. You can also select objects by the object selection functions other than drawing a selection window with the mouse. Button Label Function Select All Select all the objects. Invert Selection Select the objects other than the objects which are already selected. Deselect Deselect the objects which are already selected.
  • Page 46 Object View Functions The object view functions help you get more information from your drawing, i.e. if the contours are closed or not, the start points of the cutting path, the processing sequence, etc. Icon Label Function Show Box for unclosed To display surrounding boxes around unclosed contours.
  • Page 47 Zoom Functions Zoom functions will move, enlarge or minimize extracts from your drawing. Click on the button , or press down the arrow keys on the keyboard when the drawing window is active, to move the drawing around inside the drawing window. Scroll the mouse wheel when the drawing windows is active, or click on the button and select the corresponding function, to enlarge or minimize the extract.
  • Page 48 Object Snap Functions Use the object snap functions in order to choose geometry points precisely while drawing and constructing. For example: for catching endpoints within lines, centres of circles, tangent points of circles. Object snaps can be enabled or disabled through the pulldown-menu File>User option>User parameters. In the pop-up dialog, check the option Auto attach keypoints to enable the functions, change the value of the option Auto Attach TOL to adjust how far the mouse cursor will be snapped to key geometry points.
  • Page 49 Drawing Settings Select the menu User parameters in File>User option, or click on the button in the Basic Operation section in Home, you will see the drawing settings, which include settings for the object snap functions we just mentioned above. Here you can set which elements to display in the drawing window, set size of cursor, set background color of the drawing window, set color and font of the ruler, set highlighting of drawing elements, and others according to your preferences.

  • Page 50: Import Parts

    Import Parts You can import different file formats to CypCut. The import functions launched from the pulldown-menu File>Import import parts into the drawing window. On the other hand, the import functions launched from the menu Nest>Part import parts directly into the part library, refer to Part Library for more information.
  • Page 51 Import into the Drawing Window Let's go through the steps for importing a DXF file into the drawing window. Importing other files works just like this one. Select the command Import from the pulldown-menu File, then Import DXF File. Search for the DXF file in the Windows dialog box and click on Open.
  • Page 52 Now the software executes various activities, which you have to define or check first. Open User parameters from the pulldown-menu File>User option. These settings will be executed on the file when importing, i.e. removing tiny elements, deleting duplicated elements, etc. And then the optimized drawing of the DXF file is displayed in the drawing window.
  • Page 53 Select and remove those unwanted elements to "isolate" the contours. Finally, check the parts for open contours and correct any mistakes if necessary. Drawing Optimizations Sometimes, there are still open contours (shown in red if the view function Show unclosed curve as red is active) and other kinds of issues left in the parts after the default optimizations executed when importing.
  • Page 54 In these cases, we need to correct the issues manually by ourselves. Here is a list of the drawing optimization functions in CypCut: Icon Label Function Smooth To reduce jagged edges in polylines. Split To split curves or polylines into segments, for further treatment. Remove To remove duplicated drawing elements which are overlapping on or too close to Duplication...
  • Page 55 You can select the command Measure in the menu Home to measure the gap if you have no idea about the dimension. Just follow the prompts in the Draw command window to complete the command. Import into the Part Library The software will also execute the default optimizations when importing parts directly into the part library.
  • Page 56 The first part is the annotate in the DXF file. The second part includes the construction lines. In this case, there are elements which you do not want to import. You should follow the steps in Import into the Drawing Window to complete the importing, select the contours you want to put in the library, and right- click to bring up the context menu, then select the command Add to Part Lib.
  • Page 57 The first part is the lower half of the whole part. The second part is the upper half of the whole part. In this case, the default optimizations do not close the opening contour successfully, and the software split it into two separate parts.

  • Page 58: Construct Parts

    Construct Parts Instead of importing parts file, you can construct parts directly in CypCut, especially for simple ones. Draw Command Window The Draw command window is the most important communication platform between you and the PC while programming parts. The PC tells you which insertions it expects you to enter for the chosen command. For example, when you enter in the Draw command window, or run the function by selecting the line...
  • Page 59 Object Transformation Functions The object transformation functions will scale, move, align or rotate the selected objects. The scale functions will change the size of the selected objects, and are grouped in the menu Scale in Home. Select one or more objects and click on the menu icon to open the dialog Modify Size.
  • Page 60 You can also choose the other commands in the pulldown-menu Scale to change the size of the selected objects by a fixed width, i.e. 100mm or 200mm, or to a size times of the current size. If you want to scale the objects in the way of dragging and setting, select the command Scale, and follow the prompts in the Draw command window to complete the command.
  • Page 61 Select the command Translate to move the selected objects by dragging and setting, follow the prompts in the Draw command window to complete the command.

  • Page 65 The Line command will create a line segment immediately when the start and the end points are specified, and can be chained up to create line segments. Each line segment is separated with others and can be selected separately. Set the end point of the last line segment to the start point of the first one, choose all the line segments, and then select the command Combine near to make them a closed contour.
  • Page 66 The Text command will create a text object and activate the menu Text after you confirm the creation. You can change text, font, size and placement of the object in the menu. After creation, you need to select the command Text to Curve to convert the text object to normal contours which are ready for setting technology.

  • Page 67: Part Library

    Part Library For machining a demo, a single part, or a small amount of different parts, you can just go ahead for setting and checking technology, and then machining after preparing the parts in the drawing window. But for machining a large amount or a batch of parts, you should add them to and plan them in the part library for nesting first.
  • Page 68 In the parts list, you can get a summary of every single part, i.e. geometry, code (generated automatically), bounding frame dimension, plans and remains. Click on a part to change the code or the plans. There is a toolbar in the panel to help you manage the parts and do nesting. Icon Command Function...
  • Page 69 Right-click on a part will bring up the context menu, you can import parts, delete parts, do nesting on the part, or save the part to an external file. You can also import parts or delete all parts from the pulldown-menu Part in Nest. Sometimes, you need to set a special technology on a specific part.

  • Page 70: Nest Parts

    Nest Parts After planing parts in the part library, you can do nesting. Click on the button or on the menu icon you will see the dialog Nest, where you can set parts, sheets and technology for nesting. If there are parts selected in the library, the option Selected Parts will be enabled, you can check it to do nesting on only the selected parts.
  • Page 71 If the sheets you have are not listed in the standard sheets list, you need to construct them up in the drawing window, and select the pulldown-menu Set as plate in Nest>Plate to make the sheets. Technology for nesting are controlled by a group of parameters, to set gap between parts, set margin on sheets, etc.
  • Page 72 Click on the button OK, the software will calculate nesting layouts according to the settings, then list the results in the tab Nest plate of the Nest Panel, and display the first result in the drawing window. In the results list, you can get a summary of every single result, i.e. geometry, sequence number, sheet dimension, parts count and utilization rate.
  • Page 73 In the drawing window, you can review the current result, and optimize the layout by hand if necessary. For example, in the result shown above, there is a part in the upper right area which sticks out than the others apparently.
  • Page 74 After reviewing, you can set technology and get a result prepared for machining, refer to Technology in CypCut for more information. To generate a report on a prepared result, select the command Report Information from the context menu and complete sheet, unit price and additional information in the pop-up dialog Nest Information if you want to get extra information in the report.
  • Page 75 The software will display the report in a preview window, with page thumbnails in the left pane, and a toolbar on the top. You can walk through pages, zoom a page, print the report, or save the report to a PDF file. At last, let's have a recap on the sheets management for nesting.
  • Page 76 Click on buttons on the toolbar to manage the sheets, i.e. select all sheets, delete the selected sheets, etc, refer here for more information. Right-click on a sheet to bring up the context menu, you can delete sheets, save the sheet to an external file. Double-click on a sheet, the software will display it in the drawing window with its code showing at the top- left corner.

  • Page 77: Technology In Cypcut

    Technology in CypCut As soon as the parts are ready, you can set and then check technology, get the parts ready for machining. Hints for Setting Technology When and Where to Set Technology In general, different parts need different technology. So it is the best time to set technology after planning parts in the part library.
  • Page 78 While constructing a part, the software treats all contours as separate ones. By default, all closed contours count as outer contours no matter one contour is included in another or not, and all open contours count as inner contours. The software reconsiders their contour types when they are added to the part library as a whole, a part.
  • Page 79 For a complex part, you can select the command Sort in Home to set processing sequence and tell the software to reconsider contour types with the option Identify inner/outer contour checked at the same time. Alternately, if you want to set contour types in a reversed way, you can select the command Sort in Home with the option The outmost is inner contour checked.

  • Page 80: Cutting Parameters

    Cutting Parameters A set of appropriate cutting parameters is one of the most important technology for getting good machining results. You can set a large group of parameters, e.g. laser power, cut speed, focus position, assist gas, etc, which can control almost every single detail of a cutting process. Layers A set of cutting parameters, associated with a layer, will be applied automatically to the parts which are assigned to the layer.
  • Page 81 Sometimes, if you want to machine just a part of your design, select those parts that you want to ignore and then click on the button to tell the software to ignore them while processing. The parts which are assigned to be not processing are shown in white, but are different with the objects in the background layer.
  • Page 82 Layer Parameters To set cutting parameters of a layer, there must be at least a drawing element in the drawing window, a part in the part library, or a drawing element in the nest results. Click on the button Layer, you will see tabs for different layers and parameters grouped in the tab Cut, Pierce and Lead for each layer in the pop-up dialog.
  • Page 83 Option Description Pre- Finish piercing of all or some of the parts before cutting. pierce Defilm Burn off the protective film on the sheet along the cutting path before cutting. Recool Blow the assist gas along the cutting path after cutting to get a better cooling effect. Multi- Cut multiple times.
  • Page 84 Parameter Description Laser on Time after turning on the laser and before the laser head start feeding when cutting, helping delay get a better cutting edge at the start positions. Laser off Time after the laser head stop feeding and before turning off the laser when cutting, helping delay get a better cutting edge at the end positions.
  • Page 85 You can set piercing parameters in the Pierce tab. There are four piercing modes, no piercing, single stage, two stages and three stages piercing. Each piercing stage has a same set of parameters. Parameter Description The feeding time from the piercing height of the current stage to the height of the next Step time stage.
  • Page 86 Parameter Description Pulse freq Frequency of the PWM control signal. Focus pos Position of the focus according to the tip of the nozzle. Pierce Time after turning on the laser and before the laser head start feeding down when piercing. time Extra Time after turning off the laser and before starting the next stage.
  • Page 87 Sometimes, e.g. when cutting thick stainless steel, the piercing process will create a massive cloud of plasma which will catch a lot of laser power and result in very bad cutting results. In these cases, you should enable the special technology for leading in to lift the laser head up after piercing, blow off the plasma cloud and feed the laser head back down, and then start cutting.
  • Page 88 Lead-Ins and Lead-Outs For proper machining of a contour, the laser should pierce the material outside of the cutting path and join the contour as a lead-in. At the end of a contour the laser can be lead from the contour with a lead-out. The optimal lengths and radius of leads depend on material and thickness.
  • Page 89 Leads are shown in white, can be distinguished easily from the original contours, and can not be selected separately without the originals. The picture below shows a different result on the same part with the option Change type, keep position selected and the option Check leadline unchecked.
  • Page 90 For the type Line, the option Angle specifies the angle between the lead line and the tangent of the contour at the lead position, the option Length specifies the length of the lead line. For the type Line + Arc, the option Angle and Length mean exact the same. And a lead arc is defined with its radius specified in the option Radius, and being tangential with both the lead line and the contour at the same time.
  • Page 91 There is an exception, a lead-in to the start point of a drawing element (a line or a curve) which is not tangential with the one ahead of it will be set to the type Line regardless of the type you set. The software will try to set it to be tangential with the drawing element first, and then set it to be along with the midline of the corner if failed.
  • Page 92 Set Leads by Hand Sometimes, the positions to lead in or lead out is not as you wish or the leads interfere with the contours. In these cases, you can move the leads by specifying the lead positions by hand. Select the command Start Position in Home and then click on the contour to specify the new start position.
  • Page 93 Select the contours and select the command Gap from the pulldown-menu in Home, then set gap size in the pop-up dialog. The contours are still considered closed after being set a gap on. The gap will stick to the start position when a change made by the start position function or by setting a lead automatically.
  • Page 94 Kerf Compensation Laser kerf is the amount of material that is removed or lost in the cutting process, and, if not compensated for in the design plans, will result in loose fitting parts. Kerf Width Kerf width can vary depending on a number of factors, including the material, the thickness of the material, the laser module, the beam width and the power, the assist gas, etc.
  • Page 95 In the pop-up dialog, set both the option Outer width and Inner width to exact half the width of the kerf. Click on OK, the software will create new cutting paths, shown in white, which are the same distance from the original all the way around (we set a large value here to help you easily distinguish the new cutting paths from the original).
  • Page 96 After setting up the library, you can select the corresponding compensation setting by choosing the material and the thickness from the pulldown-lists. To remove the cutting paths created by the kerf compensation function, click on the button Clear compensation in the dialog or select the command Clear Kerf Compensation in Home>Clear when the contours are selected.
  • Page 97 Microjoints Sometimes, it is good to add some microjoints to prevent parts from falling out or hanging on while machining. The laser will be turned off automatically on microjoints which will not be cut. Set Microjoints by Hand Select the command MicroJoint in Home and then click on the contours to set microjoints. There will be a dialog, where you can set the length of microjoints, popping up when adding the first microjoint.

  • Page 100 Technologies for Getting Good Corners In general, you would get bad quality when cutting sharp corners on thin materials in high speed, and on thick materials in low speed, especially on mild steel with O as the assist gas because too much heat accumulated up there in a very small area which results in over burnt.
  • Page 101 You can also set cooling points by hand. Select the command Cooling Point in Home, the cursor will appear in a small dashed circle, and click on the contours to set cooling points until press the Esc key or select the command Cancel Cooling Point in the context menu.
  • Page 102 Ring cuts appear as dashed with laser off and as solid with laser on. If you are not happy with the ring cuts and want to make a change, just select the contours and select the command Ring Cut again, and give it a try with different settings. If you want to delete the ring cuts, just click on the button Clear path in the dialog.
  • Page 103 The relief function adds relieves on corners, avoiding warping when bending. Select the command Relief in Home. Set the radius of relieves in the pop-up dialog and then click on the corners you want to process. rev_0.6 103 / 135...
  • Page 104 Automatically Applied Technologies When Nesting Now we are finished with the technologies for getting better results on a single part. Next, we will talk about some technologies useful for a group of parts. Most of these technologies are applicable in the drawing window when nesting and constructing, and are disabled for every single part in the part library.
  • Page 105 CypCut has a set of commands for the group function, i.e. Group, DeGroup, Ungroup Selected, Ungroup All, etc. Sometimes, you can use these commands when constructing a very complex part which has several logical subsets of contours, where you can set up groups and make the editing a bit easier. Select the contours and then select the command Group in Home, the software will set them up as a group.
  • Page 106 Co-edge In some cases, the software can put parts side by side, resulting in overlapped outlines, and get optimized cutting paths by removing one pass of the overlap, save the laser-on time, make the cutting process more efficient. The software will manage to optimize the cutting paths when nesting if the automatic co-edge function is enabled in the technology settings.
  • Page 107 The co-edged contours are set up as groups automatically. The small triangles are co-edge indicators and are the start positions of the optimized cutting paths. rev_0.6 107 / 135...
  • Page 108 In case of co-edging the cutting paths generated by the kerf compensation function, the software will remove the original contours automatically, as shown below. You can also use the co-edge function when constructing a few parts for machining directly. First, move the parts side by side with overlapped outlines, the software will help you on that when the object snap functions are enabled, refer to Object Snap Functions for more information.
  • Page 109 After co-edging, there is no way to restore the original contours but rolling back the operation because they are replaced by the optimized cutting paths. The picture below shows the result of applying the command DeGroup on a co-edging cutting path. rev_0.6 109 / 135...
  • Page 110 Array Laying out parts in arrays is the basic strategy of nesting. You can also use the array function when constructing complex parts, or when constructing a few parts for machining directly. CypCut has a set of commands for the array function, i.e. Rectangular Array, Dynamic Array, Circular Array and Fill.
  • Page 111 The dynamic array function is basically an interactive mode of the rectangular array function. Select the contours and then select the command Dynamic Array in the pulldown-menu Home>Array. Set the spaces between adjacent objects in rows and columns and then click the button OK to start laying out. Left click and drag a window in the drawing window and the software will fill it with as many objects as possible.
  • Page 112 The circular array function is for laying out objects along with a circular path. Select the contours and then select the command Circular Array in the pulldown-menu Home>Array. In the pop-up dialog, check the option By Range and set the angular range for laying out in the option Array range, or check the option By Interval and set the angular space between adjacent objects in the option Degree, set the number of objects in the option Qty, click the button OK and left click the center of the circular path you want to lay out the array on.
  • Page 113 If there is no circular path to trace, you can just set up the layout in the dialog. Check the option Set Array Center, there will be an array layout shown on the right, the red circle represents the position of the selected contours in the array which can be set in the option Start angle, set the radius in the option Center radius, and click the button OK to complete the operation.
  • Page 114 The array fill function is basically a simplified version of the nest function. Select the contours and then select the command Fill in the pulldown-menu Home>Array. In the pop-up dialog, set the size and the margin of the plate, set the gap between adjacent parts, and click the button OK to complete the operation.
  • Page 115 Processing Sequence The software will sort parts in a optimized processing sequence when nesting. You can preview the sequence, change it by hand, or use the sort function when constructing a few parts for machining directly. The most simple way to preview the processing sequence is to let the software show it around the parts. Select the command Index in the pulldown-menu Home>View, then you will see the sequence index number on the contours or on the parts.
  • Page 116 Click the button to push the processing forward one step. The contours appear in bold yellow have been processed, the contour appears in bold blue is being processing, others are waiting. The picture on the left shows that the contour 1 has been processed and the contour 2 is being processing. The picture on the right shows that, after one step forward, the contour 1 and 2 have been processed, and the contour 3 is being processing.
  • Page 117 direction change to stop that. And refer here for more details on the option Identify inner/outer contour and The outmost is inner contour. If you are not happy with the processing sequence automatically generated by the software, you can change it by hand.
  • Page 118 Auxiliary Technologies In some special cases, the bridge and the fly-cut functions help you complete your jobs easier, make cutting processes more efficient, and get better results. Bridge The bridge function adds small joints between contours, makes them connecting with each other. This function is often used in two situations.
  • Page 119 Click and drag a line crossing both contours to set a bridge there. Press the Esc key or select the command Cancel Bridge Joint in the context menu to cancel the command. Second, to keep the inner pieces from being apart on openworks. For example, when cutting out some openwork letters and numbers on a plate, you need to add bridges there to keep them complete.
  • Page 120 Fly-cut You can use the fly-cut function to get a much more efficient cutting process when cutting an array of rectangles or circles. Select the array of rectangles and then select the command FlyCut in Home or select the command Linear FlyCut in the pulldown-menu Home>FlyCut.
  • Page 121 The outlines of the rectangles will be broken up and re-arranged, all the horizontal outlines will be cut in order in a linear way, same to all the vertical outlines. You can use the simulation function to check it out and get more sense about it, refer to Check Technology for more information.
  • Page 122 Select the array of circles and then select the command FlyCut in Home or select the command Circle FlyCut in the pulldown-menu Home>FlyCut. Set parameters in the pop-up dialog and click the button OK to complete the operation. The start positions and the directions of the cutting paths will be changed to accommodate the arrangement to get the most efficient cutting process.
  • Page 123 Check Technology After setting up technology, you'd better check the technology before starting machining, to confirm that all the technologies are applied in the right way, to get a brief summary of the machining progress, e.g. cutting length, traveling length, cutting time, traveling time, etc. Click the button Simu in the machining panel or select the command Simulate in the menu CNC, the software will start simulating.
  • Page 124 And, you can get a brief summary about the machining progress when simulating in the system information window. Finally, if you want to stop simulating, just press the Esc key or click the button Stop in the machining panel. rev_0.6 124 / 135...
