Embodiment Construction

[0025] like Figure 1 to Figure 6 As shown, a line cutting method of double-sided twisted web 1 is characterized in that the following steps:

[0026] 1) According to the structural analysis of the double-sided twisted web 1, the curvature of the twisted web is calculated;

[0027] 2) Combined with the calculated curvature value, set the size of the tool 4 that needs to be selected, that is, the diameter range of the tool 4;

[0028] 3) On the basis of completing step (2), determine the value of the base R of the tool 4, and select the ratio of the base R of the tool 4 to the diameter of the tool 4 within the range of 1 / 3 to 1 / 2;

[0029] 4) Divide the processed double-sided twisted web 1 into a convex area 3 and a concave area 2, and the ratio of length to width is not less than 1;

[0030] 5) Coarse row-cut double-sided twisted web 1, leaving a margin of 0.50mm to 1.0mm on the web surface, and there is a row-cut residue between the two row-cut tracks, and the residue is 0....

Abstract

The invention relates to a stroke milling method of a double-surface twisted web. Through curvature calculation, cutter selection, recessed surface area and convex surface area selection, rough stroke milling and fine stroke milling, high-efficiency stroke milling of a double-surface twisted web is achieved. The surface roughness of a machined part can be improved, the machining efficiency is high, cutter losses are small, auxiliary costs are low, and the application range is wide.

Description

technical field [0001] The invention relates to a row cutting method, in particular to a row cutting method of a double-sided twisted web, belonging to the field of numerical control processing. Background technique [0002] The invention relates to a method for line cutting of twisted webs, in particular to a method for line cutting of double-sided twisted webs. In the field of aviation manufacturing, most parts are designed along certain fixed curved surfaces, resulting in different degrees of curved surfaces in their structural shapes, which objectively increases the precision and difficulty of part manufacturing. The more common ones are The web surface is mainly twisted, and the most difficult to process belongs to the double-sided twisted web. The processing cycle of this kind of double-sided twisted web structure is long, and most of the processed surfaces need to be completed by line cutting, and the surface roughness is not easy. Guarantee, the traditional method i...
