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.<\/jats:p>","DOI":"10.3390\/ma18091894","type":"journal-article","created":{"date-parts":[[2025,4,22]],"date-time":"2025-04-22T20:11:48Z","timestamp":1745352708000},"page":"1894","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Finite Element Simulation and Optimization of Process Parameters for Titanium Chip Crusher"],"prefix":"10.3390","volume":"18","author":[{"given":"Jianghua","family":"Huang","sequence":"first","affiliation":[{"name":"School of Mechanical and Energy Engineering, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3430-2317","authenticated-orcid":false,"given":"Zeling","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Mechanical & Energy Engineering, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaomin","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, North China University of Science and Technology, Tangshan 063210, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"China MCC 22 Group Corporation Ltd., Tangshan 063035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1592-6362","authenticated-orcid":false,"given":"Hongchao","family":"Ji","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, North China University of Science and Technology, Tangshan 063210, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"G\u00f6kelma, M., Celik, D., Tazegul, O., Cimenoglu, H., and Friedrich, B.
