High-Performance Solid Carbide End Mills
Trochoidal Milling
Cutting Speed
Pressure
Heat
Reduced radial engagement infl uences the cutting speed, because the heat produced
through the cutting process limits the cutting speed.

Static Trochoidal Milling for a Full Slot
• Use a tool in which D < b.
• Programme circles in the CNC programme (as a cycle).
• After one circle, repeat the same with an offset.
• Optimise by shortening the lane “in the air” to a form like a “D”.
