This paper deals with formalism and efficiency of the system developed for generating machine axial command for multi-axis machine tool. CAD/CAM and Post-processing system have been conventionally used as off-line part programming approach. Instead of this conventional manner, a new system that is composed by unifying role of CAD/CAM system, Post-processing system, and servo command distribution system is proposed. The system is modeled in terms of a decentralized autonomous framework by treating each working component of machine tool and cutting tool as a set of information-processing elements. Machine axial command is generated from machine tool motion simulated by the system for a desired cutting tool motion. The system has the following advantages to be expected in the comparison with the conventional manner. Possible to execute necessary and sufficient gouge check, possible to evaluate the limitation of machine tool motion for avoiding unrealistic motion, and (3) possible to generate executable servo command for better surface finish.
