Programming a simple contour

Suppose you want to mill a single time around the contour shown on
the right at a depth of 5 mm. You have already defined the workpiece
blank.
After you have opened an NC block with a function key, the control
will prompt you to enter all of the data in the header using dialog
texts.
To program the contour:
Call the tool
Press the TOOL CALL key
Enter the tool data, e.g., tool number 16
Press the ENT key
Confirm the tool axis Z with the ENT key
Enter the spindle speed (e.g., 6500)
Press the END key
The control completes the NC block.
