Comparison of 4-axis and 5-axis Simultaneous Machining of Complex Shaped Blade

抄録

It is known that in multi-axis simultaneous control machining of complicated shape parts, machining accuracy may decrease due to synchronous error of the drive axes, and machining time may be longer due to excessive acceleration. In this study, in the machining using 5-axis control machining centers, in order to investigate the difference in machining accuracy and machining time depending on the number of drive axes simultaneously controlled, 4-axis and 5-axis simultaneous machining of a complex shaped blade are compared as a case study. As a result, it is found that the machining accuracy is better in the 5-axis simultaneous machining, but the machining time is shorter in the 4-axis simultaneous machining.
