Continuation of Machine Tool Technology 71A. Advanced programming of three-axis computer
numerical controlled drilling and milling machines and basic programming and operation of numerical
controlled lathes. Includes advanced contour milling, and basic lathe programming involving constant
surface speeds, tool selection, work surface programming, internal and external turning, and
threading. Prerequisite: Machine Tool Technology 71A. 2 hours lecture, 6 hours laboratory.
[Typical contact hours: lecture 35, laboratory 105]
