Method for part curve surface hole site drilling line drawing with three-dimensional model

Abstract

The invention relates to a method for part curve surface hole site drilling line drawing with a three-dimensional model. The method for the part curve surface hole site drilling line drawing with the three-dimensional model includes the following steps: (1) unfolding a curve surface of a part and correspondingly unfolding a hole site on the curve surface under the condition of a three-dimensional mathematical model, (2) conducting projection on two-dimensional model lines of the unfolded part and the unfolded hole site, and using a numerical controlled plotter to draw the two-dimensional model lines on a polyester film, (3) attaching the polyester film to the curve surface of the part, aligning the model lines with the edge of the part, and using a punch to make a round hole central point on the surface of the part, and (4) taking down the polyester film, and using a drilling tool to drill in the dotting position. The method for the part curve surface hole site drilling line drawing with the three-dimensional model can not only improve machining accuracy and machining efficiency of the hole site on the curve surface, but also reduce machining cost.

Description

technical field [0001] The invention relates to a method for drilling and marking holes on the curved surface of a part with a three-dimensional model, which is mainly suitable for curved surface parts with a three-dimensional model. Background technique [0002] When drilling and marking existing curved surface holes, it is usually processed according to the size of the three-dimensional model. When marking, the ruler is bent to measure the size. Since the holes are located on the curved surface, the size measurement is very inconvenient. If there are many holes, This results in high difficulty in scribing, low scribing accuracy, and low scribing efficiency, which in turn affects the quality and efficiency of hole processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for drilling and marking holes on curved surfaces of parts with three-dimensional models. This method not only improves the processi...
