A processing method for cabin workpiece

Abstract

The invention provides a processing method for a cabin workpiece. The workpiece includes an end face. The method includes: taking the end face of the workpiece as a reference, determining the flatness of the end face; taking the pin hole and the bottom hole on the end face as a reference, determining the rough machining center of the workpiece Carry out rough machining on the shape of the workpiece, and detect the machining allowance of each end face; according to the preset size, use the diamond milling cutter to finish the shape of the workpiece; use the finished shape as a benchmark to determine the precision of the workpiece Machining center; Use a diamond-coated milling cutter to cut the side edge and bottom edge of the end face and the end face sealing boss; Bore the pin hole on the end face; Use the pressure plate to press the groove edge of the notch; Use the spiral lower knife method, the notch is processed in sections and layers with the preset cutting step length. In this way, the processing method of datum conversion is adopted to solve the problem of uneven wall thickness caused by processing deformation under a single datum; to avoid the phenomena of slag dropping, block collapse and layering during processing.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for cabin workpieces. Background technique [0002] In recent years, with the continuous advancement of science and technology, material technology has developed rapidly. As a new type of material, composite material has gradually become one of the leading materials in the 21st century. Composite materials have the characteristics of light weight, high specific strength, specific modulus, corrosion resistance, high temperature resistance, and ablation resistance. They are ideal materials for weapons such as aircraft, missiles, and aerospace vehicles. "Metal + composite material" is a type of structural parts that are relatively common in guided weapon systems. Currently, they are mainly manufactured using technologies such as winding and suiting. [0003] As a new type of composite material, ceramic matrix composites have stronger c...
