HOLE PROCESSING METHOD CONSIDERING MACHINING ERROR OF PARTS AND HOLE PROCESSING DEVICE

摘要

The present invention relates to a hole processing method in consideration of the machining error of the outside of a part and a hole processing apparatus to which the same is applied. More specifically, the outside machining of a part for forming a machining hole precisely even when there is a difference between the designed drawing and the outer shape of the actual part It relates to a hole processing method considering an error and a hole processing apparatus to which the same is applied. The present invention comprises the steps of: a) deriving a first drawing designing the outer shape of the object to be processed and the first center position of the processing hole for the object; b) according to the derived first drawing, a step of primary processing the object to be processed so that the object has the outer shape; c) generating a second drawing by actually measuring the outer shape of the processed object; d) deriving a second central position of the machining hole by reflecting the difference in the outer shape of the object to be processed in the first drawing and the second drawing; And e) provides a hole processing method in consideration of the machining error of the outer part, characterized in that it comprises the step of secondary processing with respect to the derived second center position of the processing hole.
