I'll home-out the machine, Switch to the finish facing tool and cut for minimum clean up. At minimum cleanup, I'll leave the tool at that Z depth, and then set my work 0, And I'll set the tool's Work Geometry to Z0. Take a radial cut, again for minimum cleanup. Measure diameter, and adjust tool's X work geometry to match measured diameter.Also, never take responsibility for anything.

I set the machine up, leveled it out, wired it in. Then of course a service tech came in wearing a Mazak shirt as they were doing install work on products for SWI the maker of prototrak at the time.
This generates calibration data that the PLC uses to adjust CNC coordinates. For instance, if you have a spot on a rack and pinion rack where a tooth is slightly formed different so you shift forward 0.1mm for part of the tooth mesh and then fall back to normal at the end of the mesh, a good system can compensate.
.001 to.002 is not a sufficient move to make a cut. You are rubbing the tool with a cut adjustment of that depth. You need to adjust by more than the width of the radius/edge of your tool to produce a proper chip and not rub/burn your tool. You run your tool depth for your chamfer, measure it, adjust to depth, then cut a new chamfer. Essential Calibration Tools. To achieve precise calibration of CNC machines, several essential tools are required.

There are no retracts, no bridging, no custom heat bed settings, no temperature range for different materials. Calibration of the machine is physically dependent on you to make sure all axis are square and run true to one another. Once it runs true, the calibration is complete.
Find out what material this is, check you tool (check if inserts/endmill is damaged where they cut the material). Check your feeds and speeds. These should match your tool and material, which is why you need to know what material you are running.
