CAREER: Design and Development of Novel Responsive Cutting Tools for Laser-Assisted Machining and Diagnosis of Structural Ceramics: A Research Integrated Education Career Landscape

这个教师早期职业发展（CAREER）奖的总体目标是设计和建立一个研究综合教育计划，用于加工难加工材料。加工难加工的陶瓷、高温合金和复合材料带来了许多挑战。结构陶瓷如氮化硅在航空航天、汽车和相关工业中得到应用。然而，加工这些材料是昂贵的，并且可能引起损害材料强度的表面下裂纹。研究目标是开发新型激光集成切削工具，用于对零件数量和几何形状不敏感的结构陶瓷的经济有效的加工。切削工具将内置温度监测功能，以便在加工过程中为过程控制提供反馈。将开发加工过程的微观力学模拟，以生产具有最小亚表面裂纹的陶瓷部件。 教育部分将通过创新手段，如为本科生和研究生以及K-12地区的学生和教师建立一个新的多功能实验室，满足社区各部门的具体教育需求。研究性学习与合作性学习的整合以及有效的评估技术将为本科生和研究生提供一个动态的学习环境。该项目将为那些希望掌握该领域新技术的非传统行业学生开设难加工材料加工短期课程。该项目的潜在影响包括难加工材料加工的新刀具，热辅助加工工艺的新科学知识，以及在结构陶瓷加工领域创造世界一流的劳动力。

The overall goal of this Faculty Early Career Development (CAREER) award is to design and establish a research-integrated education program for machining difficult-to-machine materials. Machining difficult-to-machine ceramics, superalloys, and composites presents numerous challenges. Structural ceramics such as silicon nitride are finding applications in aerospace, automobile, and related industries. However, machining these materials is expensive and can induce subsurface cracks that compromise the strength of the material. The research objective is to develop novel laser integrated cutting tools that will be used for cost-effective machining of structural ceramics that is insensitive to part quantity and geometric shapes. Temperature monitoring capability will be built into the cutting tool to provide feedback for process control during machining. Micromechanical simulation of the machining process will be developed for producing ceramic components with minimal subsurface cracks. The educational components will address the specific educational needs of various sectors of the community through innovative means such as a new multifunctional laboratory for undergraduate and graduate students and area K-12 students and teachers. Integration of research and cooperative learning and effective assessment techniques will form a dynamic learning environment for undergraduate and graduate students. Short courses in machining difficult-to-machine materials will be developed for non-traditional students from industry who want to keep current with the new technologies being developed in this field.The potential impact of this project includes new cutting tools for machining difficult-to-machine materials, new scientific knowledge on thermally assisted machining processes, and the creation of a world-class workforce in the area of machining structural ceramics.
