The goal of this Small Grant for Exploratory Research (SGER) project is to investigate the potential performance of fixtures utilizing Light Assisted Adhesive Gripper (LAAG) pad technology; and, to characterize the design factors that are critical to its feasible implementation. In particular, this investigation will: (1) carry out machining tests to verify the dynamic load capacity of a LAAG pad; (2) carryout a dynamic response comparison between a dedicated fixture-workpiece system utilizing conventional technology versus one utilizing LAAG pad technology; (3) determine the necessary optical qualities of the light transmission system, and generate and test a practical design; and, (4) carry out laser release experiments in order to determine the impact of laser switching frequency, laser wavelength, laser power, and adhesive thickness on workpiece release time.In particular, the successful development of LAAG pad technology could lead to the following benefits: (1) The total exposed volume of fixturing necessary to restrain a workpiece will be significantly decreased, while simultaneously the dynamic stiffness of the fixture-workpiece system will be significantly increased. (2) Workpiece degradation due to pre-load deformation and contact surface brinelling and scratching will be eliminated.

这项探索性研究（SGER）项目的目标是研究利用光辅助胶粘夹（LAAG）垫技术的夹具的潜在性能；并且，描述了对其可行性实施至关重要的设计因素。具体而言，本研究将：(1)进行加工试验，以验证LAAG垫的动载能力；(2)对采用传统技术的专用夹具-工件系统与采用LAAG衬垫技术的专用夹具-工件系统进行动态响应比较；(3)确定光传输系统所需的光学质量，生成并测试实用设计；(4)进行激光释放实验，确定激光开关频率、激光波长、激光功率、胶粘剂厚度对工件释放时间的影响。特别是，LAAG焊垫技术的成功开发可以带来以下好处：(1)约束工件所需的夹具总暴露体积将显着减少，同时夹具-工件系统的动态刚度将显着增加。(2)消除因预载荷变形和接触面布棱和划伤引起的工件退化。
