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.

这个学院早期职业发展(CALEAR)奖的总体目标是设计和建立一个加工难加工材料的研究集成教育计划。加工难加工的陶瓷、高温合金和复合材料带来了许多挑战。氮化硅等结构陶瓷在航空航天、汽车及相关工业中得到了应用。然而，加工这些材料的成本很高，而且可能会导致亚表面裂纹，从而影响材料的强度。研究目标是开发新型激光集成刀具，用于对零件数量和几何形状不敏感的结构陶瓷的低成本加工。刀具将内置温度监控功能，为加工过程控制提供反馈。将开发加工过程的微观机械模拟，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满足社会各阶层的具体教育需求，例如为本科生和研究生以及K-12区的学生和教师建立一个新的多功能实验室。研究性学习和合作学习的融合以及有效的评估技术将为本科生和研究生形成一个动态的学习环境。将为那些想要跟上该领域新技术发展的非传统行业学生开发加工难加工材料的短期课程。该项目的潜在影响包括加工难加工材料的新刀具，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一支世界级的劳动力。
