The first one was Rigid tapping a 3/8 - 16 thread. The feed rate is supposed to be .0625 per rev. Mastercam had .087" BAM!!!
A little later, Setting up a new part. We do a lot of weldments so most of the parts you have to start somewhere because their all a little different. This means all the parts have different work offsets and tool offsets. I had ran the program earlier so I set the new part up and set the work offset then touched off the tools. I pushed the green button and BAM!!! I Rapided the 1" carbide endmill right into my part. 500 RPM's and around 350 IPM. It turns out when I was setting the work offset. I hit the Z and the X at the same time setting the offset for both. I usually keep the Z at zero. It ended up being 8" or so lower than it should have been.
