Finite Element Simulation and Optimization of Process Parameters for Titanium Chip Crusher

Titanium alloy has been widely used in aerospace, military, and national defense, and other high-tech fields due to its advantages of light weight, high specific strength, excellent corrosion resistance, excellent heat resistance, and good low-temperature performance. In the turning of titanium alloys, a significant quantity of continuous chips with poor breakability is generated. Recycling these titanium chips can effectively reduce raw material costs and minimize environmental impacts, as it decreases the dependency on primary titanium sources. The titanium chip crushing process is an indispensable part of the titanium chip recovery process, and the double-teeth roll crushing process is the most commonly used metal crushing process. Finite element simulation is an efficient, time-saving, and resource-saving method to optimize the titanium chip crushing process. In this paper, the stress change in the process of titanium chip crushing is analyzed by finite element simulation, and the influence of the number of cutter roller teeth and the speed of the cutter roller on the crushing effect of the titanium chip is analyzed. The optimal process parameters of the titanium chip crusher were obtained by response surface optimization, and the accuracy of the finite element simulation was verified by experiments, which provided a theoretical and practical basis for optimizing the titanium chip crushing process.
