Trochoidales Fräsen berechnen

Trochoidal milling radius and engagement formula

Trochoidal milling (also called dynamic milling or peel milling) uses a circular toolpath with constant radial engagement. This maintains consistent chip load and prevents the shock loads of traditional slotting, enabling higher speeds and feeds.

• Trochoidal radius = (tool diameter - radial engagement) / 2
• Engagement angle (%) = (radial engagement / tool diameter) × 100
• Typical engagement: 10-20% for hard materials, 20-40% for aluminium

How to use this Trochoidal Milling Calculator

Enter your tool diameter and the desired radial engagement (width of cut). The calculator gives the trochoidal path radius and the engagement angle percentage. Use 7-15% engagement for steel and superalloys, 15-25% for aluminium.
