Is there a possibility of shimming under the fixtures/holding apparatus of the ones that are lower so they match the highest one?

+1 I think that would be my choice for this task

You are very welcome.

Very top of dialog box try changing compensation type from computer to wear and see if that helps.

I like to refer to that as the coffee break button

I installed a pucker switch on all of our 5 axis machines. Works automatically and much faster than e-stop or feed hold.

I never even noticed that before Because I have dual monitors and MC runs on the monitor without the task bar

I just put duct tape over that button when I am not using it.

+1 ^^^ What JMC said, only I would add a countersink if allowable between drill and ream.

I have used these in the past, it was on thru holes in an aluminum casting. Once set, pre burnish bore size also an important factor, but once it was set up and going we ran thousands of parts without any issues. Is your 4340 heat treated? I have heard that with heat treated steels up to a reasonable HRC like 45-47 they work even better for surface finish in the 8 to 16 realm.

Without the proper machine and control definition and a post that is set up properly you will be hand editing.

It is probably the most versatile and easy to control multi axis tool path that mastercam has engineered into its software suite. Personally I have only been able to use it in a very limited amount of "real world" machining scenarios to date. As the company I am working for is being closed by the corporate "powers that be" and we are not taking on any new projects. However I have been playing with it in self tutorial fashion by making up my own models and pulling some old models out of archives. I have to agree that this Morph between 2 curves would have made so many jobs I have done in the past so much quicker, easier AND get better g-code as the end result. Perhaps in the future I will be able to revisit this tool path and get to watch the results actually machine a part. For now and the near future (after June 2nd) however it looks like I will be in Unigraphics land.

I know the tool path although I have not been able to implement it very often. And another problem here is that I can not view any videos at work what so ever. Corporate IT has us locked down tighter than you could ever imagine. That does not diminish my congratulations to you or my respect for your talents Milman. I have read many of your posts that have helped countless people out of trouble spots * respect *

. I think I found one you missed

Oh Boy the proverbial RCH goes from fable to fact.
