Processing method capable of preventing thin sheet part processing vibration

Abstract

The invention provides a processing method capable of preventing thin sheet part processing vibration. The method comprises the steps that 1, a coordinate system is built, cylinders with the thicknessof 25-30 mm are preserved on the surface of the position of to-be-processed holes, and the cylinders are adopted as supporting columns to support the part web portion; 2, a web is processed, and a margin of 1.5-2.5 mm is left for the thickness of a thin sheet; 3, a whirlwind milling method is adopted, primary knifing is in place, and the transverse knifing depth is ten percent of the tool diameter; 4, a milling cutter is adopted for conducting hole milling on the positions of the to-be-processed holes on the other side of the part, the processed holes are deeper than the supporting columns by0.08 mm, and then a tool is adopted to directly knock off the cylinders to obtain a product part. The processing method is high in processing precision and little in technical process, the technicalproblems are solved that in the prior art, the size precision cannot be guaranteed due to web vibration, and meanwhile, the processing process is tedious, the cycle is long, and the cost is high.

Description

technical field [0001] This technology belongs to the field of numerical control machining. It mainly solves the problem that in the actual production, due to the vibration and deformation of thin plate parts of different sizes during the processing process, it brings processing difficulties to the props and positioning of numerical control processing, and affects the processing size and surface accuracy. Background technique [0002] The processing method in the prior art is as follows: 1. During the first processing, leave 0.5mm on one side of the side wall of the part, leave 0.5mm on the web surface, and leave a finishing allowance; Plate and side wall; 3. Process the hole to be processed; 4. Loosen the plate and remove the parts, rotate 180 degrees around the Y axis, and establish a coordinate system with the reference angle at the lower right corner; 5. Carry out the second processing, leaving the rest for finishing During the processing, pay attention to the wear of th...
