Abstract

The invention discloses a grinding process method of complex curved surface blade tips for aero-engines, which comprises the following steps: a. Determining the feature points and their positions of the blade tip; Process the profiling grinding wheel and determine the position of the profiling grinding wheel; d. On-line detection of the dimensional accuracy of the profiling grinding wheel; e. Grinding and processing the tip of the blade. It can ensure the dimensional accuracy of the profiling grinding wheel and its precise alignment with the blade tip, realize high geometric accuracy, high surface quality and high-efficiency machining of complex curved blade tips, and the processing method is simple and low in cost, fully meeting industrial production Require.

Description

technical field [0001] The invention relates to the technical field of aero-engine blade surface processing, in particular to a grinding method for an aero-engine blade tip with a complex curved surface. Background technique [0002] The blade is a key part of the aero-engine, which plays a decisive role in the working performance of the whole machine. In order to meet the high-reliability and long-life service performance requirements under high temperature, high pressure and high speed, aeroengine blades are often made of highly alloyed materials such as heat-strength steel, titanium alloys and high-temperature alloys, and their processed surface quality, The processing surface accuracy and dimensional accuracy are required to be high. [0003] Aiming at the high-precision, high-quality and high-efficiency machining requirements of aero-engine blades, which are difficult-to-machine materials, researchers at home and abroad have conducted a lot of research and achieved ric...
