I have a Daewoo Lynx with a Mitsubishi M50L controller, I am trying to rigid tap a 1/4 NPT, 18 TPI.
The material is Delrin (Acetel), and im going super slow just to prove it out. Here is what I am running for a program right now.
G54
T0202 (1/4 NPT TAP)
G50S100
G97S25M3
G00X0.0Z.1
G84G98R.1X0.0Z-.5F1.3888
G40
G99
G28U0.0W0.0
T0200
M30
I have tried to run the feed in inch per rev and the results were worse, so I am running IPM. Its close, but still seems to strip out the threads.
Anyone have any ideas on this?
