CNC PROGRAMMING FOR THE CNC MILL USING G AND M CODES
In this class students will learn how to control 3-axis mill tool paths using G and M code in conjunction with tool path verification software. This course is a completely virtual learning experience.
This class is suitable for machinists, machine operators, tool makers, and anyone who wants to learn how to use code to program 3-axis tool paths. This is an opportunity to learn about the post-processed code generated by CAM software, such as MasterCam, GibbsCam, Esprit, etc.
Student should have basic computer skills, print reading skills, and some machine shop experience to enroll in this class.
