Movements :
a) In the case of rough cutting
1. Rapid traverse up to the starting point (A).
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 the opposite side of the starting point in cutting feed (FEED RATE).
5. Widening of the groove on the right and left sides symmetrically using the cutting width
(CUTTING WIDTH).
6. The side finish allowance (SIDE FINISH) is left and the groove is cut.
7. Move up along Z axis to point R
8. 3.–7. are repeated until reaching the point of the distance (BOTTOM FINISH).
9. Rapid traverse along Z axis up to point R.
b) In the case of bottom finish cutting
1. Rapid traverse up to the starting point (A).
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) up to the end
point (END POINT Z).
