Chamfer CHF

Application

The CHF chamfer function allows you to insert a chamfer between two straight lines. The size of the chamfer is based on the intersection that you have programmed with the straight lines.

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.
