Interactive Klartext course · Lesson 13 / 15
Thread tapping with CYCL DEF 209
Program a tapping operation after the correct core hole has been drilled, using pitch and depth values that match the selected tap.
What you will learn
- Set thread depth and pitch for the required thread.
- Control chip-breaking infeed and retract factor.
- Call the cycle only at prepared hole positions.
How it works
Cycle 209 synchronizes tapping motion with the programmed thread pitch. The hole must already have the correct core diameter and enough depth for the operation.
Q257 controls the infeed depth used for chip breaking. Q256 is a retract factor expressed in thread pitches; zero requests a full retract in the simulator.
