Coordinate offset direction with finishing allowance:
Δ i, Δ k define the coordinates offset and its direction of roughing, Δ u, Δ w define the
coordinates offset and cut-in direction in finishing; Δ i, Δ k, Δ u, Δ w can consist of many groups.
Generally, the sign symbols of Δ i and Δ u are consistent, the sign symbols of Δ k and Δ w are
consistent, there are four kinds of combination as Fig. 3-48,A for start-up tool point, B → C for
workpiece contour, B’ → C’for roughing contour and B’’ → C’’ for finishing path.
