Automated Process Control for Machining (CAM).

Abstract

Turning cuts were made on 4140 steel at 200 and 290 Brinell hardness with HSS and carbide tools. Computer programs were prepared for both Fortran and hand-held computers to calculate the cutting speed for turning. The programs were based on a Fundamental Machinability Equation that includes the tool material and shape, the size of cut and size of the workpiece. Programs were also written for surface finish and horsepower requirements, and for time and cost analyses and control. Test applications demonstrated capabilities, in quickly and accurately controlling machining rates for maximum production and/or minimum cost rates, far surpassing the use of contemporary handbook data and manual methods.
