State of the art in the field of force prediction in ball end milling

Abstract

Abstract: Simulating the process of NC milling is of fundamental imporlance in computer aided design (CAD) and computer aided manufacturing (CAM). Cutting force prediction is very imporlant to optimize machining parameters and monitor machining state. In order to predict cutting force of suiface machining with ball end mill, contact state between cutter and workpiece are studied. The resulting surface quality after machining with ball end cutter is of superior imporlance because finish milling is often the last process step determining the JUnctional performance of a component. In this paper is presented the state of the art in the field of force prediction in ball end milling and advantages of different methods for determining the cutter­ workpiece engagement.
