Abstract
This paper describes a procedure to calculate the optimum cutting conditions for turning operations with minimum cost or the maximum production rate as the objective functions. For a given tool/workpiece combination, the search for the optimum is confined to a feed versus depth of cut plane which is defined by the chip-breaking constraint. Some of the other constraints which are considered by the system include power available, workholding, surface finish and component accuracy. If more than one pass is necessary to rough machine a given area, the optimum depths of cut calculated for each pass may have to be modified. Four different methods of doing this are discussed. To demonstrate the system, the cutting conditions for machining a simple component are presented.
