9315758 Geskin High pressure waterjet machining is extensively used in the cutting of non-metallic materials. While abrasive particles can be added to the jet to machine metallic materials, such modification reduces the life of the nozzle and associated equipment and the beam diameter typically increases. The project is to investigate the feasibility of modifying the high pressure waterjet machining process to transform the water microdroplets into ice. It is expected that such a modification will significantly increase machining rates to a range somewhere between that of conventional waterjets and that of abrasive waterjets. It is also expected that the beam diameter can be significantly smaller than that of conventional abrasive waterjets, increasing the resolution of the operation. Ice jets may allow materials to be cut more quickly and with better accuracy, allowing the high pressure waterjet process to find new industrial applications.

9315758 Geskin 高压水射流加工广泛应用于非金属材料的切割。 虽然可以将磨料颗粒添加到射流中来加工金属材料，但这种修改会缩短喷嘴和相关设备的寿命，并且光束直径通常会增加。 该项目旨在研究修改高压水射流加工工艺以将水微滴转化为冰的可行性。 预计这种改进将显着提高加工速率，使其达到传统水刀和磨料水刀之间的某个范围。 预计光束直径可以明显小于传统磨料水射流的直径，从而提高操作的分辨率。 冰射流可以更快、更准确地切割材料，从而使高压水射流工艺找到新的工业应用。
