SGER: Ice Jet Machining

小行星9315758 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以加工金属材料，但是这种修改降低了喷嘴和相关设备的寿命，并且射束直径通常增加。 本计画系探讨改良高压水射流加工制程，将微水滴转化为冰的可行性。 预计这样的修改将显著地增加加工速率到介于常规水射流和磨料水射流之间的范围。 还可以预期的是，光束直径可以显著小于传统磨料水射流的光束直径，从而提高操作的分辨率。 冰射流可以使材料更快地切割，并具有更好的精度，从而使高压水射流工艺能够找到新的工业应用。

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.
