You are looking for no-load monitor

hy teahole, please forgive me, i don't wanna be seen as speaking in cotradiction, so please consider that i would take you to a wild bunny hunt anytime

is not LM2, because "We are having issues with operators running parts more than once resulting in oversized bores" has a big chance to be an operation with really low tolerance, thus cutting it again may put the part out of tolerances

such stuff is hard to be felt by the cnc, because the tool cuts nothing ... pls check latest posts in here : http://www.cnczone.com/forums/okuma/...tor-stuff.html

i did not replied for mr bjhall06, but for you, because you are a sharp guy all the best

you can't monitor load on a finish cut no matter what

you can check spindle effort before and during cutting, thus knowing the load that the cutting forces create

if this load is little, and this would be a mass production issue, you may increase the material volume that the finish tool cuts ... just a bit more effort

if rough and finish operations are done with different tools, and is desired for finish tool to cut only 0.10 .. 0.15, to make this stable is required a tool senzor that measures tool diameter ... otherwise, on less equiped cncs, such stuff requires more often controling parts dimensions before the finish operation, and so on ... not to say the case when a finish tool was just changed, part dimensions before finishing are ok, and still the tool will trash your part

on single parts this is an issue when machining duration is big, and finish tool should cut a specific cutting depth, otherwise faster wear may occur, and :
... maybe is a chance that the part will be accepted with a low discontinuously on the finish surface
... if material is hard, and discontinuously surfaces are not allowed, ...

i hit the last case when doing molds for pills ( pharmaceutical industry )

Neither of those things will help ... discipline ;-)

that's the spirit thinking out off the box + technical background
