a) In the case of rough cutting
1. Rapid traverse up to the starting point.
2. Rapid traverse along the Z axis up to point R (END POINT Z + REMOVAL DEPTH +
CLEARANCE)
3. Descent along the lower Z axis in cutting feed (Z-CUT FEED RATE) by the pitch
(REMOVAL PITCH).
4. Cutting from the inside to the outside using the same cutting width (CUTTING WIDTH)
in cutting feed (FEED RATE).
5. After cutting, side finish allowance (SIDE FINISH) remains.
6. Rapid traverse along Z axis up to point R
7. Rapid traverse back to the starting point (A).
8. Rapid traverse down to the cutting surface + clearance (CLEARANCE) along Z axis.
9. Advance in –Z axis by the pitch (REMOVAL PITCH) and repeat steps 3. to 8. up to the
point of the distance (SIDE FINISH).
10. Rapid traverse along Z axis up to point R.
b) In the case of bottom finish cutting
