Creating a CNC Milling Program 302

Creating a CNC Milling Program illustrates the process of creating a part program for a CNC mill. Writing the part program is only one step in the process of creating a part. The toolpaths created within a part program depend upon the sequence of operations necessary to machine a part. Different G code programming codes perform the different tasks within the part program, from setting speed and feed to activating rapid positioning. Canned cycles and subprograms help to short the length of part programs. All programs need to be checked by proving out. Programming and how it relates to the axes on a CNC mill are critical for a programmer to successfully create a part program that produces accurate parts. After taking this class, users should be able to describe how to write a part program that machines a basic rectangular part on the CNC mill.
