An Active Processing Method for Clamping and Deformation of Thin-walled Special-shaped Parts

Abstract

The invention discloses an active processing method for clamping deformation of thin-walled special-shaped parts. First, the clamping force of the thin-walled workpiece is optimally set, and then the range of the force point of the workpiece is found out, and then the workpiece is supported auxiliaryally, and finally the compensation is performed. The data is imported into the CNC program. Compared with the prior art, the active machining method for clamping and deformation of thin-walled special-shaped parts can be analyzed before numerical control machining of thin-walled parts to determine the magnitude of the clamping force, identify the clamping point and the support point of the workpiece, Using increasing and decreasing tool compensation, the clamping of the workpiece is stabilized, the cutting deformation of the workpiece is reduced, and the accuracy is further improved.

Description

technical field [0001] The invention relates to a workpiece processing control method, in particular to an active processing method for clamping deformation of thin-walled special-shaped parts. Background technique [0002] In the CNC machining of thin-walled parts, the clamping accuracy of the parts to be processed is one of the key links that affect the quality and efficiency of parts processing. Because thin-walled parts, especially large thin-walled special-shaped parts, have small wall thickness, poor rigidity, and complex shapes, they are prone to large deformation during clamping, which affects their processing accuracy. In the past, there was no complete set of thin-walled parts. In order to reduce the processing deformation, the most used method is to use multiple corrections, but this cannot fundamentally avoid deformation. When studying the clamping of thin-walled parts, it is necessary to study the factors that may cause clamping deformation from various aspects...
