Space Curved Surface Numerical Control Macro Program Milling Programming and Simulation

Abstract

In numerical control machining, the mode of automatic programming by CAD/CAM software for machine program has already been popularized. Relative to automatic programming, user macro program is the advanced form for numerical control programming, there are many advantages in the usage of production, but the degree of recognition in production is not very high, and the programming level macro program of employed person is not high. This article aims at FANUC numerical control system, analyzes the curved surface and the relevant equation from the perspective of analytic geometry, divides the commonly-used curved surface of numerical control milling, proposes programming ideas of macro program through case comparison, programs macro program corresponding to curved surface machining to conduct simulation of numeric control simulation tool path line, and simultaneously offers proposal for variable setting of macro program programming so as to reasonably program milling macro program in production according to the curved surface machining characteristic. Furthermore, this article also improves productivity on the premise of product quality assurance.
