Multi-Axis Control Ultraprecision Machining Based on Tool Setting Errors Compensation

Abstract

Initial position errors generated while setting cutting tools can deteriorate machining accuracy. However, because of the manual setting process, it is difficult to prevent the tool setting errors, which can increase in accordance with the number of the control axes. These errors make it difficult to locate the tool accurately at the correct position in multi-axis control machining. Therefore, this study aims to achieve multi-axis control ultraprecision machining based on tool setting errors compensation. From the conducted experiments, it is found that the proposed method is effective for compensating the tool setting errors in multi-axis control ultraprecision machining.
