ajst-23469	Feng, Ling	Study on Rock Breaking Efficiency of Non Planar PDC Teeth	2024	5	.pdf	application/pdf	4001	184	63	In actual single tooth rock breaking experiments, the scraping distance of PDC teeth is 300mm. China Abstract: In order to explore the law of rock breaking efficiency of existing non planar teeth in sandstone, indoor single tooth rock breaking experiment and numerical simulation of rock breaking are carried out for planar teeth, sharp circular teeth and axe teeth, and the effects of different eating depth and rake angle on rock breaking efficiency of PDC teeth are analyzed.	cache/ajst-23469.pdf	txt/ajst-23469.txt
