The Process of Programming
First, examine the drawing and determine such conditions as the workpiece material, the size of the workpiece to be prepared, the tool
diameter, the tool type, the proper turning speed, and the proper feed rate. Then determine the sequence in which to cut. The cutting
sequence is in extremely important point for carrying out cutting efficiently and safely.
In actual cutting, the moving portion may be either the workpiece or the spindle. Programming is carried out with consideration given
to how the tool moves, with no distinction made for the actual movement.

Once the appropriate conditions and cutting sequence for the job have been determined, then before cutting is begun, the programming
steps are written down on a piece of paper like the one shown below. (This form is called a "process sheet.") This sheet is handy for
confirming the cutting sequence and numerical values.
