Sawblade cutting page produces tangential motion of a disk geometry for a given 2D geometric model.
Disk geometry definition comes by tool selection. The tool must be a cylinder. Its diameter and height values should be the same as sawblade diameter and thickness.
2D geometric model selection is called contour selection on this page. A contour is a connected set of 2D geometric elements such as lines, circular arcs, splines, conic arcs, etc. A contour is always on the X-Y plane of the active coordinate system.
1. Open the sawblade cutting page.
You can do this by menu command sawblade cutting under machining. Clicking the same icon on the toolbar will open the page, too.
2. Select a contour geometry.
If you do not select any geometry then the last selected set will be used when you press calculate.
After selection, define a start point for contour ordering. Be careful! Complete the selection! Otherwise, calculations may fail or use the previous selection.
Contour selection is done by selecting curve objects or Solid2D objects.
Solid2D objects can be created from Shapes 2D or macro tables.
Imported DXF or IGES files add curve entities. You may convert these to Solid2D objects.
3. Select your tool.
Use a tool with the same dimensions as your sawblade. If not available, create it using the Tool Dialog page.
4. Enter the part height.
This is the plate thickness.
5. Enter safe Z value.
Must be higher than part height to avoid cutting in the air move phases.
6. Define cutting parameters.
Enter max cutting depth for arcs and lines. Define separate feed rates for circular and linear moves.
Cutting feed rate is used while the tool is cutting. Entry feed rate is used during plunge moves. Link feed rate is for fast air moves (G00 if set to 0). Exit feed rate is for retraction after cutting.
Spindle value is the RPM of the sawblade.
7. Enter plunge height.
This is added to the first cutting Z position. Must be greater than max cutting depth.
8. Define liftup value.
Moves the entire tool path along Z+. Different from Z overcut, which can also move angularly if bevel cutting is applied.
9. Set stock to leave.
Offsets toolpath on X-Y plane. Positive makes it larger, negative makes it smaller.
10. Trim and extend tool trajectory.
Use drop list options to control start and end trimming.
11. Select machining side.
Choose correct side for outer boundary and inner holes.
12. Taper angle parameters.
Used for bevel cutting (e.g., 45° side walls). Select "some edges" if not all walls are inclined. Then assign taper values to specific edges.
Set taper height equal to part height to cut entire wall angularly.
13. Set type to Segment.
Common for stone and ceramic cutting.
14. Tool rotates CCW option.
Used if your controller supports M codes for rotation direction. Affects post-processor output.
15. Geometry filter options.
You may choose to machine only lines or arcs in complex parts.
