ajst-30371	Deng, Junhao	Waterjet Cutting Sandstone Ability Test and Process Parameter Optimization Research	2025	12	.pdf	application/pdf	6682	326	51	When the jet working pressure exceeds 50 MPa, the solid-liquid mixture within the rock fissures similarly weakens the impact velocity of subsequent abrasive water jets; however, under higher impact dynamic pressure, the stagnation pressure within the rock fissures significantly increases, which is beneficial for secondary fracturing of the rock, possibly being the main reason for the rapid increase in rock cutting depth once again. Therefore, the inflection point where the rate of increase in rock cutting depth due to increasing waterjet horizontal movement speed is the optimal horizontal movement speed for the waterjet.	cache/ajst-30371.pdf	txt/ajst-30371.txt
