Abstract:As the auxiliary function of FANUC system, PMC axis can be controlled freely independent of CNC axis with no hardware limitations. The control method of FANUC PMC axis in NC rotary worktable was discussed and the application example in high pressure blasting machine was illustrated. The control scheme was analyzed, and the NC system hardware configuration was illuminated. Based on the specific control requirements of rotary worktable, the key steps of PMC control were elaborated. The program flow diagram was drawn, and several PMC programs were given.
