Abstract

The invention discloses a double-sided machining deformation control method and equipment. The double-sided machining deformation control method and equipment is characterized in that a blank is divided into an adjustable area and a non-adjustable area according to an adjustable range of the position of the part in the blank, and the position of the part in the blank is adjusted according to the monitored deformation data in the adjustable area; all the characteristics of the double sides of the part are considered in the finish machining stage, the double-sided finish machining sequence is optimized, and the deformation of the part after final machining is small. In order to realize the machining method, the double-sided machining deformation control equipment is provided, the clamping force and the machining stability can be guaranteed on the premise that the clamping force and the machining stability are ensured, the double sides of the part can be machined through one-time clamping, and meanwhile the deformation data of the part are monitored through a displacement sensor. According to the double-sided machining deformation control method and equipment, the final deformation ofthe part is ensured, and meanwhile, the clamping automation and intelligence are realized.

Description

technical field [0001] The invention relates to a precision machining machining technology, in particular to an anti-deformation processing technology for web parts, in particular to a double-sided machining deformation control method and equipment. Background technique [0002] Large-scale aviation parts have complex shapes and high material removal rates. After processing, due to the redistribution of internal residual stress, the workpieces are often severely deformed or even scrapped. How to control the deformation of aircraft structural parts is very important. Processing on both sides of the part can balance the processing deformation caused by material removal. Now the commonly used double-sided processing method is to repair the benchmark on both sides, then carry out rough machining on side A—manual turning over—rough machining on side B—manual turning Surface - A side semi-finishing - manual turning - B side semi-finishing - manual turning - A side finishing - manu...
