Linear cutting machining method for whole-circumference outer contour metal sheet part

Abstract

The invention provides a linear cutting machining method for a whole-circumference outer contour metal sheet part, and belongs to the technical field of machining. The linear cutting machining method comprises the steps that (1) a metal sheet to be machined is fixed to a machining base plate; (2) carrying out first cutting on a part of the outer contour of the circumference on the metal sheet to be machined; (3) the circumferential outer contour cut for the first time is connected with a body of the metal sheet to be machined, and meanwhile a plurality of conductive metal sheets are arranged at the joint; (4) cutting the rest part of the first cutting for the second time; and (5) machining of the whole circumferential outer contour of the metal sheet is completed. According to the invention, the outer contour of the circumference cut for the first time is connected with the body of the to-be-processed metal sheet during the second time of cutting, and falling is avoided, so that no joint mark is formed at the joint, and the processing qualified rate is improved.

Description

Technical field [0001] The present invention belongs to the field of machining, and the processing technique involved in the circumferential contour, specifically a line cutting process of the entire circular outer contour metal thin plate part. Background technique [0002] For air parts, the accuracy requirements of their parts are very high. For airborne high-precision, round-week metal sheet parts, generally used wire cutting techniques for processing. During the machining process, to ensure the requirements of the verticality, coaxial degree of the processing surface of the line cutting process, and considering the feasibility of the line cutting process, the air use of existing line cutting processes High-precision round-peripheral metal thin plate-like parts have a larger inclusion, resulting in a large number of outer contours and positional tolerances of the part; and the prior art line cutting method requires two-way finding, secondary finding process Increase the labor...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned existing wire cutting technology, when processing high-precision full-circumference metal sheet parts for aviation, during the processing process, the cut part will fall under the action of gravity, and the problem of joint marks at the joint , the present invention proposes a wire-cutting processing method for the entire circumference outer contour metal sheet parts
