A Study of Computerized Process Planning with Continuous and Discrete Data Base

Abstract This paper discusses methods for the computerized selection of machining variables to increase productivity and optimize economics of machining. An attempt has been made to use the computer for process planning in situations for which the relationships between the machining variables and the performance measures are complex and nonlinear functions with discrete values. An algorithm is presented which deals directly with the problem of a discrete data base. A comparison of continuous and discrete data base methods for process planning was made using the Electro Discharge Machining (EDM) process.
