Physics-based Modeling and Optimization of High-Performance Machining
Abstract
High-performance machining delivers maximum achievable part quality, process competitiveness, and ecological compatibility through strategic utilization of cutters, machine tools, operation configuration, and process parameters. To this, a thorough understanding of the underlying mechanics affecting performance attributes such as tool life, part integrity, air quality, etc., and how they are attributed to tooling conditions, operation configuration, and process parameters, is required.This presentation reviews and summarizes a series of Physics-based analysis methodologies to explore the fundamental mechanics of machining in the context of thermal, mechanical, tribological, and metallurgical microstructure effects and their interactions. In this study, cutting temperatures, cutting forces and stresses, grain size evolution, crystallographic orientation change, phase transformation, residual stress, tool life, and aerosol generation are quantitatively described as explicit functions of tool geometries, cutting speed, chip load, cutting fluid properties, interface tribological conditions, and the cutter/workpiece material constants.The analyses facilitate the prediction of machining performance attributes thereby allowing up-front planning of machining processes in achieving first-and-every-part-right manufacturing.
