Optimization of control programs for numerically controlled machine tools by dynamic programming

A method of calculating optimal control programs is briefly described for the example of grinding with transverse supply on metal-cutting machines with an automatic control cycle based on active monitoring. The control parameters of the grinding cycle are optimized by dynamic programming. The optimization procedure is insensitive to the nonlinearity and differentiability of the control model, the target function, and the models of the technological constraints. The number of constraints on the target function is unlimited. Optimization of any type of machining cycle is possible by this means. © 2015, Allerton Press, Inc.
