EXAMPLE:
Assume that a drilling operation is to be programmed as:
1. The tool is positioned at (25.4,12.5,0) by a rapid movement.
2. The tool is then advanced -10 mm in the z direction at a feed rate of 500 mm/min., with the
flood coolant on.
3. The is then retracted back 10 mm at the rapid feed rate, and the coolant is turned off.
