This Small Business Innovation Research (SBIR) Phase I seeks to develop a micro-abrasive-waterjet nozzle for machining features between 50 to 100 micrometers. The project is extremely challenging because abrasive waterjet (AWJ) machining involves an ultrahigh-speed, 3-phase flow engaging in complex solid/fluid interactions within very small dimensions that are changing rapidly. The project is aiming to minimize the beam diameters of abrasive waterjets, reshape and refocus the jet stream exiting the nozzle, improve flow characteristics of fine abrasives, and mitigate abrasive clogging. The micro-abrasive-waterjet nozzle with a single-feed port will become the most compact size of its kind by eliminating the vacuum assist and water flushing requirements needed to prevent abrasive clogging. The recent advent of micro-nano, green energy, and biomedical technologies has created tremendous opportunities for low-cost micromanufacturing. The micro-abrasive-waterjet will take advantage of the inherent merits of waterjet technology -- versatility (material independence), cold cutting (preservation of material integrity), cost effectiveness, and fast turnaround -- that are unmatchable by most established tools. The final goal is to further downsize abrasive waterjet nozzles toward micromachining, meet the high demand for low-cost micromanufacturing and further boost the market share of waterjet machine tools.The broader/commercial impact of waterjet micromachining will be machining fits well within the 'just-in-time' practice of lean manufacturing; using waterjet machining, small and large parts/lots made from most materials can be completed from design to finish in hours -- something that is not possible through outsourcing them abroad. This project's development of waterjet micromachining will promote waterjet technology for high value-added jobs and further sustain its phenomenal growth. Inserting additional waterjet systems into the manufacturer arena would not only raise the awareness of this technology but also help save jobs from being outsourced overseas. This could have an important society impact through planting the seeds needed to help rebuild a sustainable U.S. manufacturing industry, leading to reversing the three-decade long trend of the continued shrinkage of domestic manufacturing workforce, and revitalizing the once prosperous manufacturing business toward a recovery of America's economy.

这项小型企业创新研究（SBIR）I阶段试图开发一个微型 - 水喷嘴，用于50至100微米之间的加工特征。该项目极具挑战性，因为磨料水夹（AWJ）加工涉及在非常小的尺寸迅速变化的非常小的固体/流体相互作用中参与复杂的固体/流体相互作用。该项目的目的是最大程度地减少磨料水夹的光束直径，重塑和重新聚焦在喷嘴中，改善喷嘴，改善精细磨料的流动特性，并减轻磨料堵塞。带有单次喂养端口的微型 - 磨蚀水喷嘴将通过消除真空辅助和防止磨碎堵塞所需的水冲洗要求，成为同类中最紧凑的大小。微型纳米，绿色能源和生物医学技术的最近出现为低成本微制造带来了巨大的机会。微型 - 磨难 - 水喷气机将利用水夹技术的固有优点 - 多功能性（物质独立性），冷切割（保存材料完整性），成本效益和快速的周转 - 这些工具是无与伦比的。最终的目标是进一步缩小磨料的水夹喷嘴朝着微加工，满足对低成本微型制造的高需求，并进一步提高水夹机床的市场份额。水夹微机械加工的更广泛/商业影响非常适合' - 时代'精益制造的实践；使用水夹机加工，大多数材料制成的小零件/批次可以从数小时内完成到完成 - 这是通过将它们外包给国外的。该项目的水夹微机械加工将促进高增值工作的水夹技术，并进一步维持其惊人的增长。将其他水夹系统插入制造商竞技场不仅会提高对这项技术的认识，而且还可以帮助挽救就业机会，从而避免出国外包。这可能会通过种植帮助重建可持续的美国制造业所需的种子来产生重要的社会影响美国的经济。
