New Orleans, Louisiana Paper Number: IMECE2002-MED-PPO-03 ADAPTIVE FEEDRATE SCHEDULING AND MATERIAL ENGAGEMENT ANALYSIS FOR HIGH PERFORMANCE MACHINING

ABSTRACT This paper presents a technique of feedrate scheduling by analyzing the material removal volume when a tool moves in linear, circular, or parametric curved motions. Tool motions of different types of endmilling cutters are considered in this study. By studying the relationship between the cutter geometry and the tool motion, the material removal rates of different cutters are analyzed. The adaptive feedrate scheduling can be determined to maintain a constant cutting load. The technique developed in this research can be used for tool path generation in CAD/CAM systems for 2.5D NC machining
