A generalized cutting location expression and postprocessors for multi-axis machine centers with tool compensation

摘要

This research deals with tool compensation and postprocessor development for numerical control application. The content consists of three main activities. First, derives a cutting location expression of the tool for compensation and machining stability use. Second, establishes an analytical methodology to develop a kinematics transformation algorithm (KTA) for the specific type machine with a swivel spindle head and two rotary tables. And last, defines correspondent between workpiece and the cutter to attain the aim of three-dimensional tool compensation and presents postprocessors under KTA for two types of five-axis machine centers in examples.
