Abstract

The invention belongs to the technical field of milling of cast steel weak-rigidity structures and discloses a machining method of a large-sized large-tapered half-enclosure thin-walled cast steel housing. The machining method includes the steps of designing a housing machining process; allocating machining allowance; carrying out a clamping process; designing a milling tool path; selecting tool and cutting parameters. The machining method herein helps solve the problems that parts with poor rigidity are difficult to clamp during machining, interior and exterior profiles have large chatter marks, tools break easily, machining efficiency is low, product quality is unstable, and the application requirements cannot be met.

Description

technical field [0001] The invention relates to the technical field of milling machining of weakly rigid structural parts of cast steel materials, in particular to a machining method for a large-scale large tapered half-cover thin-walled cast steel shell. Background technique [0002] Due to its high strength, easy casting and low cost, large integral steel castings are gradually being designed and used in aerospace vehicle tests. "Large large taper, thin wall, integral cast steel material" are the main characteristics of this type of structural parts. At present, mold casting is mainly used, and the product manufacturing is completed through mechanical processing after casting. [0003] "Large, large taper, thin-walled, integral cast steel material" half-cover shell has the following characteristics: (1) The rigidity of the part structure itself is poor, the processing standard is difficult to determine, and the clamping is difficult; (2) The amount of material removed from...
