7.11 TROCHOIDAL SLOT (Cycle 275,
DIN/ISO: G275)
Cycle run
In conjunction with Cycle 14 CONTOUR GEOMETRY, this cycle facilitates
the complete machining of open and closed slots or contour slots
using trochoidal milling.
With trochoidal milling, large cutting depths and high cutting speeds
are possible because the equally distributed cutting conditions prevent
wear-increasing influences on the tool. When tool inserts are used the
entire cutting length is exploited to increase the attainable chip volume
per tooth. Moreover, trochoidal milling is easy on the machine
mechanics. Enormous amounts of time can also be saved by
combining this milling method with the integrated adaptive feed
control AFC software option (see User's Manual on conversational
programming).
Depending on the cycle parameters you select, the following
machining alternatives are available:
îš„ Complete machining: Roughing, side finishing
îš„ Only roughing
îš„ Only side finishing
