I have about a dozen quality 1/4" HSS end mills that no longer cut well. I usually run my end mills until I can't tolerate the burr they leave on the parts. I've been looking into getting some of these re-sharpened since they are mostly OSG and Niagra end mills that are still in good shape, but just dull.

When re-sharpening the end mills they take about .010" off the diameter.

My question is, how do I compensate for that with the Taig Mill. I don't want to re-write all my programs. Is there a way to just program in some sort of offset? I'm using DeskCNC controller software which supports most of the gcode commands.

I have never used the G41/42 commands for cutter compensation. I tried reading up on it a bit and couldn't quite follow it. Would this be the right approach? Sounds like I may still need to go in and modify my programs but I am not sure.

Was hoping there was a simple way to just offset the tool slightly and allow the mill to run the exact same program making the parts to the proper size.

Thanks,

Terry
