Embodiment 1

[0082] 1 Select the appropriate plunge milling tool according to the material and structure of the part;

[0083] The plunge milling tool is selected according to the part material and the shape and surface characteristics. The processing material is INCOL 718 nickel-based superalloy. The larger area uses a φ40 plunge milling cutter, and the rather narrow area uses a φ32 plunge milling cutter.

[0084] Determine the plunge milling process parameters according to the selected plunge milling tool;

[0085] F40M plunging milling blade specification is 12×6, in principle, the width of plunging and milling should not exceed the width of the blade, generally select 1 / 2 of the width of the blade as the width of plunging and milling, the cutting speed is 40 m / min, each tooth cuts 0.2mm deep.

[0086] 2Use the multi-axis milling function of UG software to generate a tool path with a fixed step;

[0087] On the UG platform, the multi-axis machining method is adopted, and the variable...

Abstract

The invention discloses a five-axis plunge milling method of an aeroengine crankcase, which is characterized by comprising the technical processes of part processing technology analysis, technology route formulation, cutter selection, cutting parameter selection, numerical control programming and processing. The invention overcomes the key technique of generating the paths of five-variable-axis plunge milling cutters of complex crankcase pieces, provides an effective means for crankcase processing, improves the crankcase processing efficiency and reduces the processing cost. The method can be used in the technical filed of numerical control processing of the parts of the aeroengine crankcases.

Description

technical field [0001] The invention relates to milling processing technology, and in particular provides a five-axis plunge-milling processing method for an aero-engine case. This technology belongs to the technical field of CNC machining of aero-engine casing parts. The plunge milling technology is applied to the five-axis CNC milling of complex casing parts, which solves the technical key to the generation of complex casing five-coordinate variable-axis plunge milling tool rails. The five-coordinate high-efficiency CNC milling of the outer surface of complex casing parts of aero-engines has been realized. Background technique [0002] Plunging and milling processing technology uses a drilling-like processing method to remove most of the margin on the surface of the part. It has the characteristics of high processing efficiency and has been applied in the mold processing industry. However, it only has the function of fixed-axis plunging and milling, and does not have five-...
