CNC/HAAS newbie here....
I keep breaking taps. I'm trying to tap some 10-32 holes in aluminum. The holes are drilled .159 and I have countersunk them a bit for a good lead in. I was using a spiral flute tap to tap some holes in 1/2" thk aluminum. I talked to HAAS this afternoon but was not at the machine to verify that rigid tapping is actually turned on (I'm 99% sure it was turned on when we bought the machine with the option). I was trying to run them at 500RPM with a feed of 15.625.
Ok...now reading this I see 15.63 in the code...is that my problem?
Here is the code...with the tool previous to it. This is programmed in HSMworks.
Thanks for your help.
