Embodiment Construction

[0010] The specific steps of the process optimization method for complex thin-walled parts of the present invention are as follows:

[0011] Step 1. Clamping the workpiece: observe the structure of the part, and select a certain plane with a larger area as the clamping surface. You can make your own or purchase a vacuum clamping platform. Place the selected clamping surface stably on the vacuum platform. After the platform vacuum device starts and the parts are fixed, the parts can be processed. If the part does not have a plane that can be clamped, you can make a craft boss with a plane that can be clamped. The clamping process is performed as above. After the processing is completed, the boss is cut off without affecting the original structure of the part.

[0012] Step 2. Select the cutting tool: When the processing reaches the finishing stage, the original ordinary cutting tool is replaced with a corresponding type of cutting tool with vibration-absorbing ribs according to...

Abstract

The invention discloses an optimization method of a complex thin-wall part processing technology, and aims at solving the technical problem of low processing accuracy of an existing optimization method of the thin-wall part processing technology. According to the technical scheme, the optimization method is characterized in that a vacuum assembling method is adopted for assembling; a blade with a damping edge is provided; an offset swing program is added to a cutter according to the deformation degree based on an original cutter running track while numerical control programming is carried out during finishing, thus compensating the cutter relieving amount caused by deformation. According to the method, the thin-wall part processing technology is optimized from three aspects, namely, assembling deformation, cutting deformation and vibration deformation; the problems such as incomplete optimizing effect caused by an experience-based parameter optimization method can be avoided; the problem of deformation of a complex thin-wall part in processing can be effectively solved. Therefore, the processing accuracy is improved.

Description

technical field [0001] The invention relates to a method for optimizing the processing technology of thin-walled parts, in particular to a method for optimizing the processing technology of complex thin-walled parts. Background technique [0002] The literature "Process Analysis and Examples of CNC Machining of Special-shaped Parts, Science and Technology Communication, 2012, (12), p140-141" discloses a process optimization method for CNC lathe processing of thin-walled parts and gives a reasonable processing plan. This method analyzes the deformation problem of turning processing of complex thin-walled parts, and summarizes the two main deformation causes of clamping and vibration. Aiming at this problem, a specific optimization method is proposed in three aspects of clamping method, tool selection and programming, which effectively improves the processing quality and precision of parts. The method described in the literature clamps the workpiece by the three-sided support...
