Impact of Machining Parameters on Machine Reliability and System Productivity

This paper analyzes the impact of machining parameter selection on machining system productivity. The method involves prediction of machine tool reliability from mechanical failure based on process choices and production rate. The machine reliability is then input to a machining system production configuration to estimate productivity. Through a simple turning model example, it is demonstrated that an optimal production rate for maximum productivity exists. The best system configuration for maximum productivity is shown to be affected by the level of machine reliability and the choice of process parameters.
