With the chamfer function CHF you can insert a chamfer at the intersection of two straight lines.
Application
Requirements
- Straight lines in the working plane before and after the chamfer
- Identical tool compensation before and after the chamfer
- Chamfer is machinable with the current tool
Description of function

Cutting two straight lines creates contour corners. You can insert a chamfer at these contour corners. The angle of the corner is irrelevant; you simply define the length by which each straight line is shortened. The control does not traverse to the corner point.
If you program a feed rate in the CHF block, then this feed rate is in effect only while cutting the chamfer.
