Creating a CNC Turning Program

“Creating a CNC Turning Program” illustrates the process of creating a part program for a CNC lathe. Part programmers use G code programming to perform the different tasks within a part program, from describing the location of a cutting tool to setting the feed and speed. Canned cycles help to shorten the length of part programs. A part programmer needs a thorough understanding of G code programming and how it relates to the axes on a CNC lathe to 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 cylindrical part on the CNC lathe.
