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 + BOTTOM REMOVAL +
CLEARANCE)
3. Descent along the lower Z axis in cutting feed (Z-CUT FEED RATE) by the pitch
(BOTTOM PITCH).
4. Cutting movement (FEED RATE) toward the center by the pitch (SIDE PITCH) .
5. Side cutting with the cutting width of the pitch (SIDE PITCH).
6. 4.-5. are repeated up to the point of the distance (SIDE FINISH).
7. Move away the amount (CLEARANCE) along the Z axis.
8. Rapid traverse back to the starting point (A).
9. 3.-8. are repeated up to the point of the distance (BOTTOM FINISH).
10. Rapid traverse along Z axis up to point R (END POINT Z + BOTTOM REMOVAL +
CLEARANCE).
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 + BOTTOM REMOVAL + CLEARANCE)
3. Descent along the lower Z axis in cutting feed (Z-CUT FEED RATE) up to the point
(END POINT Z).
4. Cutting movement (FEED RATE) toward the center by the pitch (SIDE PITCH) .
5. Side cutting with the cutting width of the pitch (SIDE PITCH).
6. 4.-5. are repeated up to the point of the distance (SIDE FINISH).
7. Move away the amount (CLEARANCE) along the Z axis.
c) In the case of side finish cutting
1. Rapid traverse up to the starting point (B).
2. Rapid traverse along the Z axis up to the cutting point + CLEARANCE.
(Cutting point : It is calculated by END POINT Z, BOTTOM REMOVAL, BOTTOM
PITCH, CLEARANCE)
3. Descent along the lower Z axis in cutting feed (Z-CUT FEED RATE) up to the cutting
point.
4. Cut into the workpiece following a circular path.
5. Cutting of the side finish allowance (SIDE FINISH).
6. Move away from the workpiece following a circular path after cutting.
