calculate the BEST Revolution (RPM) and Speed (Feed Rate mt/min) of your tools using :
Diameter (mm), number of cutter, type of material, average Peripheral Cutting Speed (Vp mt/sec),
quality of Cutting (mm).
With 5 steps you can configure and test your tools in a second. With this easiest way you can understand what really append if you go more faster with Feed Speed or if you change the RPM.
