Course Description
This course is a continuation of MT 210. It will cover such topics as cutter compensation, fixed and variable
canned cycles, subroutine programming, and the circulation of machining forces as they relate to the efficiency
of the machining process. Part programs will be written for the lathe, the vertical mill and the horizontal mill.
