Pocket machining is a method of generating planar toolpaths using regions as the part geometry limits. Here the 3-D part geometry model is not considered in the toolpath generation. Instead the input regions are used to construct a virtual 3-D part geometry model that has vertical walls with the top edge defined by the regions Z values or a user specified value and has an XY shape defined by the regions geometry.

The toolpath begins at the top Z value and stops at the bottom Z Depth defined by you. The cut patterns that used in this type of machining can either be a linear cut pattern or an offset cut pattern.
