Abstract
The examination of the economics of multi-pass machining operations has significant practical importance, particularly in the development of algorithms for process planning, and area clearance macros for numerically controlled machine tools. The authors show that, for both turning and milling operations, the optimal widths of cut may usually be evaluated without a knowledge of the relevant tool-life equation. The exception to this finding occurs when either a power or torque constraint is active. The authors demonstrate that in the presence of such constraints the optimal widths can still be evaluated without extensive computation.
