My first attempt was not to make a tapered hole for the thread mill. I was using a Vardex TMNC 075. The code I was proving was provided by Vardex some time ago. The other mills in the shop occasionally do a 1"NPT. I think they run the code 2x's with changing offsets. Anyway the short of it is, the load on the tool proved excessive.
My compromise to get a tapered hole G3 spiraling Z- with the correct dimensions was to define the Diameter of the tool as .0001". This does give me the code I need. If I start increasing the tool diameter, over cutting happens.
I think Edgecam is doing something bad in the threadmill routine. |
