Embodiment Construction

[0018] Deformation control method for NC machining of slender and complex T-shaped parts, such as Figure 1 to Figure 4 shown, including the following steps:

[0019] 1) Divide the processed slender and complex T-shaped parts into two left and right sub-packages, namely sub-package I and sub-package II;

[0020] 2) Carry out rough machining of sub-package part I and sub-package part II and make positioning datum plane and positioning hole;

[0021] 3) Subassembly Ⅰ and subassembly Ⅱ are fixed on the processing table of CNC milling machine through fixed tooling;

[0022] 4) Use the shallow cutting processing method to perform contour cutting on the parts;

[0023] 5) Reserve machining allowance for assembly parts;

[0024] 6) Weld subassembly I and subassembly II into a whole and perform heat treatment;

[0025] 7) Complete the machining process of slender and complex T-shaped parts.

[0026] The specific method of the step 4) is: adopt the cutting method of equal height o...

Abstract

The invention provides a method for controlling numeric control machining deformation of a slender and complicated T-shaped component, which comprises the following steps of: 1), dividing the machined slender and complicated T-shaped component into a left subpackage member and a right subpackage member, i.e. a subpackage member I and a subpackage member II; 2) performing coarse machining on the subpackage member I and the subpackage member II and manufacturing a positioning reference plane and a positioning hole; 3) fixing the subpackage member I and the subpackage member II on a numerically-controlled milling machine machining table board through a fixed tool; 4) performing equal-height drop layer ring cutting on components in a shallow-cutting machining way; 5) reserving machining allowance to an assembling part; 6) welding the subpackage member I and the subpackage member II into a whole and carrying out thermal treatment; and 7) completing the machining process of the slender and complicated T-shaped component. By adopting the method, the deformation of the tail part of the assembly before the welding of the component can be eliminated in the numeric control machining process, and the deformation amount is removed.

Description

technical field [0001] The invention relates to a method for controlling deformation in numerical control machining of parts, in particular to a method for controlling deformation in numerical control machining of slender and complex T-shaped parts. Background technique [0002] It turns out that in the field of CNC machining, if you encounter a slender T-shaped part, the part will be deformed in each process of the processing process, and the final correction will be laborious, which may seriously affect the final processing size of the part and cause the part to be scrapped. Therefore, deformation control in machining is very important for subsequent processing, which directly affects the processing quality of subsequent parts. Contents of the invention [0003] The purpose of the present invention is to provide a deformation control method for NC machining of slender and complex T-shaped parts, which can eliminate the tail deformation of the component before welding of ...
