SGER: Ice Jet Machining

Geskin高压水射流加工广泛应用于非金属材料的切割。虽然可以在射流中添加磨料颗粒来加工金属材料，但这种修改会减少喷嘴和相关设备的寿命，并且通常会增加光束直径。该项目是研究修改高压水射流加工工艺，将水微滴转化为冰的可行性。预计这种改进将显著提高加工速度，其范围介于传统水射流和磨料水射流之间。此外，预计光束直径可以明显小于传统的磨料水射流，提高操作的分辨率。冰射流可以使材料切割得更快、更精确，从而使高压水射流工艺找到新的工业应用。

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.
