Research and Development of Economical CNC Software for 2D Lean Friction Stir Welding Machine

Abstract

This project is developing a two-dimensional friction stir machine, relatively low cost to achieve four axis friction stir welding equipment with real-time servo control, where the corresponding trajectory planning function in cam is relatively independent by making a full use of Galil motion controller has a strong multi axis linkage control capability and fast real-time communication capabilities and the Galil motion controllet G code analysis software module is developped. This paper is studying the trajectory planning software system design and development of friction stir for different trajectories in the plan and is aiming to solve the motion trajectory control problem with complex welding path. A deep study of three polynomial spline function trajectory planner is done, and the complex motion trajectory of the multi axis welding machine controlled by acceleration and speed is realized. The micro arc transition approximation method is applied to optimize the inflection point with abrupt change of track path and achieve smooth inflection motion.
