These properties render the composites prone to fiber fracture, burr formation and matrix damage during grinding for hole-making. This study systematically investigates the material removal mechanism, tool wear behavior and machining quality evolution process during diamond core drill grinding for hole-making. Through experiments, the effects of grinding angle and grinding force and the thermal effects on material removal characteristics and hole wall machining quality were analyzed, and the stagewise characteristics of tool wear and the correlation between processing parameters and machining quality were clarified. The results indicate that the wear of diamond core drills undergoes a three-stage evolution: slight abrasive grain shedding at the initial stage, local damage and wear loss at the middle stage, and large-scale abrasive grain peeling followed by tool failure at the late stage. As wear aggravates, the machining axial force increases remarkably and the grinding temperature rises drastically. Hole wall defects gradually develop from minor initial fiber fracture into complex failure modes including burrs, fiber pull-out and matrix damage. In particular, the morphological degradation at the hole exit is the most severe. This study verifies that the optimization of process parameters and tool design can improve machining quality, and provides theoretical guidance and an experimental basis for the efficient and precise machining of high-performance composites.<\/jats:p>","DOI":"10.3390\/ma19143007","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T08:53:58Z","timestamp":1783932838000},"page":"3007","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Experimental Study on Grinding for Hole-Making of 2.5D C\/SiC Composites Using Diamond Core Drills"],"prefix":"10.3390","volume":"19","author":[{"given":"Bing","family":"Chen","sequence":"first","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Liu","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"},{"name":"School of Intelligent Engineering, Xiangtan Institute of Technology, Xiangtan 411100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiwei","family":"Sun","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rukai","family":"Liu","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weicai","family":"Quan","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Yi","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ye","family":"Guo","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of High Efficiency and Precision Machining of Difficult-to-Cut Material, College of Mechanical Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"544","DOI":"10.1177\/09544054241235743","article-title":"Toward understanding the damage behavior during orthogonal grinding of 2.5D C\/SiC composite based on multi-scale modeling and high-speed photography","volume":"239","author":"Liu","year":"2025","journal-title":"Proc.
