This paper presents a method of machine instruction code generation for multi-axis machine tool instead of the conventional manner. In the present method, each working part of multi-axis machine tool, cutting tool, and fixture are modeled as autonomous components and a mechanical simulation system is constructed by these autonomous components to simulate machining operation for multi-axis machine tool. NC instruction codes are generated by extracting motion of working parts made by performing mechanical simulation system model as the operative closure system served by mutual feedback among autonomous components under the constraints that are relation among working parts, cutting condition between cutting tool and workpiece, and interference with motion of cutting tool. This paper describes the concept of NC instruction code generation by performing mechanical simulation system as the operative closure system proposed in this study and details of evaluators and operators coded into the autonomous component for constructing such mechanical simulation system. Then effectiveness and feasibility of the proposed method has been estimated by performing the simulation and actual machining.
