But it will still run now don't it?If the program will run with a smaller cutter without breaking it, it wasn't optimized for the larger one
At the same time, the program won't run with a larger tool and scrap it now does it?
That said, me thinks you're just trying to make an argument for your style of programming.
How many here optimizes the very last bleeding 1% out of their programs?
Not that I use many regrinds for finishing ( they are typically relegated for roughing with comp ), but often I switch to a metric EM for finishing in tight corners, all that without having to repost or change anything in the program.
