The research objective of this award is to formulate a methodology and system for the micro-manipulation of a waterjet serving as a laser beam waveguide leading to the development of a new multi-functional hybrid waterjet-guided laser micro-manufacturing process and machine capable of laser ablation, micro-cutting, surface micro-texturing and modification and micro-incremental forming. The salient characteristic of the envisioned process rests in the possibility of simultaneously using thermal and mechanical actions with different attributes in controlled proportions. The approach will be the use of a controlled electrostatic field generated by a multi-pole actuator to bend the waterjet waveguide and, thereby, control the spatial orientation, the position of impingement, direction of lasing action and the force the waterjet exerts on the workpiece. The principal tasks will be: (1) waterjet waveguide characterization; (2) waterjet bending and control through an electrostatic actuator; (3) waterjet-guided micro-incremental forming process development; and (4) construction of an experimental prototype machine to serve as a vehicle for process model and technology verification.If successful, this research will lead to a new ability to manufacture three-dimensional micro-features on metallic and non-metallic parts without relocating the part, which will lead to enhanced precision. The physical interaction of the waterjet and laser beam will open process windows for achieving deformation, cutting, and surface treatment of the workpiece material in a single hybrid integrated manufacturing machine. Process productivity will be considerably enhanced because of the anticipated high process bandwidth. The project will provide training to a diverse group of graduate and undergraduate students and practitioners through research opportunities, course projects and short courses.

该奖项的研究目的是制定一种方法和系统，用于用作激光束波导的微型操作，从而开发新的多功能混合水夹引导的激光微型制造过程，并能够通过激光消融，微型微调，微型微型，微型融合和改良的形式和MICKRECTION和MICKERTIAL和MICKERTIAN和机器。设想过程的显着特征在于使用具有不同属性的热和机械作用同时以受控比例的方式使用的可能性。该方法将是使用由多极执行器产生的受控静电场来弯曲水夹波导，从而控制空间方向，撞击的位置，激光动作的方向以及水夹在工件上的力。主要任务将是：（1）WaterJet波导表征； （2）通过静电执行器弯曲和控制的水夹； （3）水剥水引导的微型灌溉过程发展； （4）构建实验原型机器，以作为过程模型和技术验证的工具。如果成功，这项研究将导致新的能力在金属和非金属零件上生产三维微功能，而无需重新安置零件，这将导致精确的精确度。水夹和激光束的物理相互作用将打开工艺窗户，以在单个混合集成的制造机中实现工件材料的变形，切割和表面处理。由于预期的高过程带宽，过程生产率将大大提高。该项目将通过研究机会，课程项目和短期课程为各种研究生和本科生和从业人员提供培训。
