Approach means the path the tool takes to arrive at the first point of an engage or plunge move either from a tool change position or from the last position of the previous operation.
Usually, an approach move consists of two steps:
- Tool movement with rapid feedrate at either the <Safe plane> (for 3D operations ) or, at the <Safe coordinate> (for 5D operations).
- Tool movement with rapid feedrate to the first position of either the engage or the plunge move of the first working toolpath, this is either along the Z axis (for 3D operations) or along the tool axis (for 5D operations).
