Trochoidal milling with SINUMERIK Operate

Cycle for milling open slots

SINUMERIK Operate offers the operator a trochoidal milling function, thus enabling the machining of open grooves. This strategy is often used to machine grooves with a high depth of cut on weaker machines as well as in steel qualities with high tensile strength.  The milling path results from combining the continuous rotation of the milling cutter with a linear feed movement, thus creating a “slab milling process.” The chip cross section at the cutting edge is always the same size, resulting in a reduced machine and tool load and making it possible to run significantly higher cutting values.
