In the last ten years, trochoidal milling has come on leaps and bounds thanks to advanced software and computing power. In trochoidal milling, the tool follows an elliptical path in order to keep cutting forces constant and minimize the load on the milling cutter, which has a positive effect on tool life.
This milling method is particularly suitable for machining deep slots and shoulders. Due to the low radial depth of cut and the short cutting time per tooth, trochoidal milling produces fewer chips per revolution. This enables the use of more cutting edges and ensures efficient chip removal. Trochoidal milling offers significant advantages in terms of tool life, machining time and load, particularly when machining hardened materials or titanium alloys.
