Hi Everyone!
I was always told to ignore TNR in lathes because it's stupid and causes more problems that it is worth, etc. Nevertheless I want to at least learn about it. Please see the attached picture. The very last sentence on the page he says, "If the above program is modified to the following version, the face will never be completed! Think about it!"
Well I HAVE thought about it and cannot figure out why the face wouldn't be completed! It seems to me that N21-N24 which are identical) would both face the part to X-.07 the same. The chamfer even looks like it would end up being the same to me. The only difference I see is the path the tool would take to end up at X1.0 Z0.1
Can anyone explain what I am missing on this??
Thank you!
