Abstract

The invention discloses a method for processing an inner cavity web, which belongs to the technical field of aviation metal cutting and processing. The machining coordinate system of the part; c. Rough machining the front side of the inner cavity web and the reverse side of the inner cavity web of the part to be processed; d. Finishing the reverse side of the inner cavity web of the part to be processed to the preset size; e. Machining the inner cavity web The front side of the verification area and the back side of the inner cavity web verification area; f. Measure the actual thickness of the front side of the inner cavity web verification area and the back side of the inner cavity web verification area, calculate the difference between the actual value and the theoretical value, and then calculate the difference Compensate to the program of finishing the front side of the inner cavity web; g. Finally finish machining the front side of the inner cavity web of the part to be processed to the preset size, and complete the processing of the inner cavity web. The invention can not only meet the processing requirements of the inner cavity web, realize no manual intervention in the processing process, but also improve processing efficiency and processing precision.

Description
