Method for eliminating tiny deformation in batch forming of slender thin-wall crack line sources

Abstract

The invention belongs to the technical field of numerical control precision machining and manufacturing, and provides a method for eliminating tiny deformation in batch forming of slender thin-wall crack line sources. According to the method, the sizes and the positions of the line sources are measured by designing a special clamp and utilizing a machine tool probe; then, the clamping pretightening force is judged and finely adjusted; and the values about the deviations between the two-end positions of each crack on a waveguide top surface and datum points are collected point by point as wellas recorded in a machine tool macroprogram for being called by a machining program so as to compensate for the tiny deformation. Consequently, the influence of such comprehensive subtle factors as thewaveguide tube section size deviation, the straightness, the twisting degree and the tiny deformation generated in the production process as well as the difference among waveguide tubes on the precision of the crack line sources can be creatively eliminated; the coincidence between the process datum and the design datum can be guaranteed; the deformation, caused by the clamping, of thin-wall waveguide tube cavities can be reduced; and the machining precision can be improved.

Description

technical field [0001] The invention relates to the technical field of numerical control precision machining and manufacturing. Background technique [0002] Due to the influence of comprehensive factors such as waveguide cross-sectional size deviation, straightness, twist, and thin-walled waveguides due to poor rigidity and variability in the structural characteristics of slight deformation in the production process, the difference between each waveguide is superimposed. Even the different positions of the same waveguide have slight differences. Many comprehensive subtle differences will seriously delay the clamping and alignment time in the processing of slender and thin-walled crack line sources, especially in batch molding, resulting in the center line of the waveguide and the Inconsistent processing standards reduce the quality of line source processing. Contents of the invention [0003] In order to ensure processing quality, improve production efficiency, realize f...
