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。加工难以加工的陶瓷、高温合金和复合材料提出了许多挑战。结构陶瓷如氮化硅在航空航天、汽车和相关工业中得到了应用。然而，加工这些材料是昂贵的，并可能诱发地下裂纹，损害材料的强度。研究目标是开发一种新型激光集成切割工具，用于对零件数量和几何形状不敏感的结构陶瓷的经济高效加工。刀具将内置温度监测功能，为加工过程中的过程控制提供反馈。加工过程的微观力学模拟将用于生产具有最小次表面裂纹的陶瓷部件。教育部分将通过创新的方式满足社会各界的特殊教育需求，例如为本科生和研究生以及地区K-12学生和教师提供一个新的多功能实验室。将研究性合作学习与有效的评估技术相结合，将为本科生和研究生形成一个充满活力的学习环境。将为来自工业界的非传统学生开设加工难加工材料的短期课程，这些学生希望了解该领域正在开发的新技术。该项目的潜在影响包括加工难加工材料的新切削工具，热辅助加工工艺的新科学知识，以及在加工结构陶瓷领域创造世界级的劳动力。

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.
