In 5-axis machining, the movement of machine tools is complicated, and the machining process is not intuitive and difficult to predict collisions between spindle and fixture, spindle and rotary table, tool holder and workpiece. Jingdiao virtual processing technology constructs the same digital scene in CAD/CAM software, simulating the entire process and eliminates the risk of collision at programming stage to guarantee the safety of 5-axis machining.
