磨料射流加工的主要参数对冲蚀体积的影响

Effect of Abrasive Waterjet Parameters on the Removal Volume

试验研究了前混合磨料射流加工的主要参数（压力、磨料重量比浓度、靶距、横移速度、磨料粒径大小等）对冲蚀体积率的影响。试验结果表明：压力增大，冲蚀体积率增大；在其它参数不变时为获得最大的冲蚀体积率则有一最佳的磨料重量比浓度和横移速度及靶距；磨料粒径大小对冲蚀体积影响不大。

Research and experiments are made on the effects of main parameters (pressure, specific concentration of abrasive by weight, target distance, traverse speed, abrasive grain-size, etc. ) on the volume removal rate in pre-mixed abrasive waterjet cutting. The experimental results show that the volume removal rate is increased with higher pressure. An. optimum specific concentration of abrasive by weight, traverse speed and target distance will get the highest volume removal rate while keeping up other parameters unchanged. The abrasive grain-size has a little effect on the removal volume.
