Blades play a vital role in the performance of aeroengines. Under normal operating conditions, a large number of parts and components in aeroengines need to work in harsh environments of high temperature, high speed, and high pressure for a long time, and each part is required to operate stably and have a long life. Therefore, aero-engine blades are usually made of difficult-to-machine materials such as titanium alloys and high-temperature alloys, and require high machining accuracy. After the titanium alloy blade is milled, the workpiece profile will leave obvious tool path dents (depth 20~50μm) and surface hardened layer. The machining accuracy and surface quality are far from reaching the final quality requirements. The final machining of the blade profile is almost Generally rely on surface finishing. At present, titanium alloy blades are mostly polished manually. Affected by manual operation, the surface integrity and consistency of the polished area cannot be guaranteed, the polishing efficiency is low, and the cycle is long, which cannot meet the mass production requirements of the product. Some parts are still The existence of damage to the substrate or blades brings hidden dangers to product quality. It can be seen that conventional processing technology is difficult to meet the needs of product processing. In order to improve the life and reliability of engine parts, it is urgent to carry out research on complex profile blade grinding technology, and improve product quality and processing efficiency through research on related manufacturing technology and intelligent technology. . This paper firstly analyzes the technological applicability of abrasive belt grinding and industrial robot intelligent processing to the grinding of titanium alloy blades, and then conducts experimental research on the titanium alloy blade robot abrasive belt grinding experimental platform, and finally detects and tests the polished blades. Evaluation.
