Abstract
This study compares the motion characteristics of 5-axis machine tools with Japanese and European NCs under wing profile machining. Productivity is one of the most important factor in the industrial field. It is known that the cycle time of the machining process typically depends on the manufacturer, control mode, and setting of the NC controllers, even though the identical cutter path is applied. In order clarify the influence of the manufacture and control mode of the NC controllers onto the cycle time and velocity profile of the machining, wing profile machining tests are carried out by 5-axis machining centers with different type of NCs. Identical CL data is used for the tests. Effect of TCP control mode on to the cycle time and velocity profile is also investigated. As the results, it is clarified that the TCP control mode can significantly reduce the cycle time. In addition, it is clarified that the jerk is limited when the European NC is used although the acceleration is limited in case the Japanese NC is used.
