How to Use This Calculator
- Enter axial depth of cut (DOC) and radial width of cut (WOC) in inches or mm.
- Set the feed rate (IPM or mm/min) from your machining parameters.
- Review material removal rate (MRR) in in³/min and cm³/min.
- Check required horsepower for aluminum, steel, and stainless to verify spindle power is sufficient.
- Reduce DOC or feed rate if required HP exceeds your machine's rated spindle power.
