In the Approach tab of the Roughing cycle you can specify that Trochoidal milling should be used for full width cuts (that is cuts that exceed the specified % stepover).
In a narrow channel there may not be room for a trochoidal cut, in this case the channel is excluded from the cycle.
When using Trochoidal milling the tool cannot run as tightly into corners. These areas can be cut with the Rest Roughing cycle.
