Study on Cutting of Difficult-to-Cut Material Blade

By building the tool wear forecast model and combining the model theory and production practice, and ensuring the quality requirement of machining quality, cutting parameters are given to maximize the effectiveness of difficult-to-cut material (GH2132). These parameters are verified during the blade surface machining of aeroengine, which achieves the optimal combination of machining quality, efficiency and cost and provides the important basis and solve method for cutting parameterization of aviation difficult-to-cut materials. This method is very important for enhancing machining efficiency and reducing cost.
