Optimization Design and Research on Macro Program of Archimedes Spiral Machining

By analyzing the characteristics of Archimedes spiral equation, this equation takes included angle as variable, and algorithm equal straight line approximation can be used to calculate interpolation points. Using advantage parametric programming by FANUC system macro program, a G instruction(G102) is customized realize machining surface. This instruction in same way system’s inherent code, similar custom fixed loop code. It different from program number that code must indicate when calling program. The G102 complete Archimedean surface only assigning values each letter according format specified text. After processing verification on GLU28x40 CNC, use method flexible convenient cycle provided CNC. process profile meets requirements, for interpolation. calculation speed fast, which effectively improves efficiency profile.
