Understanding CNC Machine Accuracy and Repeatability ...

I define a CNC machine tool's accuracy as how precisely its axes can follow intended paths to commanded end points while under load. I define its repeatability as how precisely it can duplicate commanded motions (again, under load) during multiple cycles throughout the day. These are definitions for dynamic accuracy and repeatability.

Milling Finish: Complete Guide [ Tips, Techniques, and ...

– Climb mill with this 2/3's cut ratio. Conventional milling with a face mill causes the chip to start out thin, which sometimes leads to rubbing at the outset of chip formation that is bad for surface finish and can lead to BUE. The best finishes start the chip out fat and then thin it out before the chip releases.

milling machine rigidity - Practical Machinist

My test was to mount a dial indicator on the vise and see how much the spindle deflected when a calibrated force was applied to the head. My arms served as that calibrated force, so my results are only as good as my repeatability on the two mills, which I'd estimate to be ~20%. Deflection when pushing upwards on the head: Millrite: 0.0005"
