Interactive Klartext course · Lesson 14 / 15
Chamfering with DL and DR tool offsets
Use temporary tool-length and tool-radius delta values to place the cutting flank of a countersink on a hole or contour edge.
What you will learn
- Understand DL as a delta to tool length and DR as a delta to tool radius.
- Apply offsets only for the operation that requires them.
- Verify the effective tool geometry and resulting chamfer in simulation.
How it works
DL and DR supplement the active tool data in a TOOL CALL block. They can shift the programmed reference point so a specific part of a shaped tool follows the target edge.
The required values depend on the real tool geometry and setup. The lesson demonstrates the simulator workflow; production values must always be verified independently.
