12. Using the handwheel, infeed to the next depth of cut in the X direction.

13. Start machining in the Z axis in the negative direction using the axis direction switch.

Repeat the procedure until the depth of rough cut is reached.

The message "Limit stop -X reached" is displayed as the tool is fed in.

Once this cut has been completed, adjust the limit stops to the finished dimension,

provided that the axes are positioned in front of the workpiece.

Operating sequences for adjusting to finished dimension

1. Adjust the limit stops to the finished dimension: -X to 50.0 mm/-Z to –100.0 mm

2. Using the handwheel, infeed in the X direction until the "Limit stop -X reached" message

appears.

3. Start machining in the Z axis in the negative direction using the axis direction switch.

When the limit stop position in Z –100.0 mm is reached, the Z axis stops automatically.

The message "Limit stop –Z reached" is displayed.

4. Switch-out the axis direction switch in the Z direction and start in the positive X direction

(finishing the end face).

5. Switch-out the axis direction switch in the X direction as soon as the tool tip leaves the

workpiece.
