Trochoidal Pocket & Profile

This plugin adds a two new machining operations that perform a trochoidal machining to cut pockets or profile.

This new operation appears in the Machining menu and in the toolbar.

The generated toolpaths are some kind of HSM peeling. Pocket is opened with the expanding flat spiral, followed by a number of trochoidal slices. Slices are rolling along the branches of underlying tree, covering the whole pocket.

Also have a look on this topic if you want to enhance this plugin capabilities with a post processing of the produced GCode.

Documentation	Plugin is done as a new kind of MOP, so usage is straightforward - pick polylines and go, just as for the usual Pocket MOP MOP-specific parameters: Chord Feedrate - feedrate for the slices chords. Also applies to the movements inside the pocket. Plugin tries to eliminate most of Z movements, so there would be some moves inside the milled area. If 0 cut feedrate is used Spiral Feedrate - feedrate for the spiral used to "opening" the pocket. If 0 cut feedrate is used Minimum stepover Plugin tries hard to keep the specified stepover all the time. This may result in undercut corners. Use this parameter to relax stepover requirements. Show Chords Display the chord moves Smooth chords Replace straight chords with smooth arcs to form a continous toolpath. This may be useful on a machines with slow acceleration. Not applied to the the mixed milling direction. Plugin is experimental, use it with care. Bugs are expected. Simulation and/or air cutting are recommended.
Requirements	CamBam 0.9.8 P, Linux version, V1.0
