Speed & Feed Calculator
For HSM Machining & Trochoidal Milling
These recommendations are made for High Performance carbide end mills with YG-1’s “Y” Coating, or other advanced PVD coatings (i.e., AlTiN, AlCrN, nACRo, etc.)
The recommended speeds and feeds should be used with
- an axial depth of cut equal to 2 to 4 times tool diameter (i.e., for a ½” diameter tool, take 1” up to 2” axial depth)
- and a radial depth of 8% of diameter (i.e., for a ½” diameter tool, take a 0.040’’ radial depth)
With lower radial depths equal to 4% , then both RPM and feed rate can be increased by 50%
