To complete a typical operation, the operator does the following:

1.examines the workpiece to make sure it is suitable for milling.

2.Firmly clamps the workpiece to the table or a mill vise.

3.installs the correct cutting tool for the opera- tion.

4.uses the manual downfeed and table con- trols to correctly position the cutting tool and workpiece for the operation. If the X-axis power feed will be used during the operation, the operator confirms the speed and length of table movement required.

5.Configures the mill for the correct spindle speed of the operation.

6.puts on personal protective gear, and makes sure the workpiece and table are clear of all tools, cords, and other items.

7.starts the spindle rotation and performs the operation.

8.turns the mill OFF.
