THE DEVELOPMENT OF THE NC METHOD OF ELIMINATING MACHINING POINT ERRORS CAUSED BY MACHINING CENTERS FIRST REPORT (Theory)

摘要

(1). The geometrical error vector model showed the relation of the machining point errors to the detected errors and the fixed coordinates of the detectors. (2). The actual tool feed was calculated from the data of all detected in-process errors using the model above. (3). Our NC method enabled the elimination of machining point errors by feedback of the actual tool feed to the servomotors of the tool.
