Approach

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:

1. Tool movement with rapid feedrate at either the <Safe plane> (for 3D operations ) or, at the <Safe coordinate> (for 5D operations).

2. 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).
