@Vince.Fab posted some really impressive results using his 60,000 RPM spindle with aluminum. I added fields to the attached workbook so he/others could also log temperatures for the endmill. workpiece, and chips if they can and care too. I could also add one for noise level (SPL) but it seems that might be best done in the cutting videos(?). Note that the VFD currents entered may be inaccurate because they suggest a K factor twice what was expected.
