Abstract

The invention relates to a high-efficiency milling process method for split casings, which adopts cycloidal milling tool path, large depth of cut, small width of cut, and fast feed process parameters. The steps are: high-efficiency milling tool path planning; using large depth of cut , small cutting width, high feed speed mode, and optimize cutting parameters; high-efficiency milling tool path planning includes: select the tool path of helical feed and cycloid opening pre-processing groove; select the cycloid reciprocating tool path; pendulum Arc transitions are used between lines to avoid right-angle turns. The method of the present invention is applied in the face milling process of the outer shape of the aircraft engine opening case. The processing method adopts the cycloidal tool path, large depth of cut, small cutting width, and fast feed, and utilizes the advantage of the long edge of the tool to cut the surface of the opening case. It can be used in profile milling to improve the utilization rate of tools. In terms of reducing costs and improving processing efficiency, it realizes high-efficiency milling of open casings and improves processing efficiency.

Description

technical field [0001] The invention relates to a processing technology for an aero-engine casing, in particular to a high-efficiency milling process method for a split casing. Background technique [0002] The aero-engine is the core component of the aircraft, and the base of the entire engine of the casing is the main load-bearing component on the aero-engine. Aero-engine casings are mostly made of titanium alloys, high-temperature alloys and other high-temperature-resistant and difficult-to-cut materials. At present, medium and low speed cutting methods are usually used for the face milling of the split case of aero-engines, the cutting speed and feed rate are low, but the cutting depth is large, resulting in large cutting volume, high cutting force, and large processing deformation. question. Contents of the invention [0003] Aiming at the deficiencies such as large cutting volume, high cutting force, and large processing deformation in the face milling of the shape...
