Estimate approximate spindle power based on width of cut, depth of cut, feed rate and specific cutting force.
Typical Kc values (very rough):
• Aluminium: ~600–800 N/mm²
• Low alloy steel: ~1500–2200 N/mm²
• Stainless steel: ~2200–2800 N/mm²
Always use values from toolmaker or material data when available.
