Optimal cutting parameters are a science:
-
Key Concepts: Surface footage (SFM), chip load (IPT/MMT), depth of cut, width of cut.
-
Calculation Formulas: RPM = (12 × SFM)/(π × D), Feed rate = RPM × # of flutes × chip load.
-
Material‑Specific Values: Aluminum, mild steel, stainless steel, plastics, composites—recommended ranges.
-
Tooling Factors: Flute count, helix angle, coating—how they affect chip evacuation and heat buildup.
-
Live Testing: How to adjust feeds & speeds on the fly based on sound, finish quality, and power draw.
Master these calculations to eliminate chatter, maximize removal rates, and extend tool life.
