This Faculty Early Career Development (CAREER) award supports fundamental research and education on mechanical micromachining of engineering materials. Mechanical micromachining refers to the application of milling, drilling, turning, and grinding at the micro scale. The research objective of this CAREER plan is to understand and model the effects of material grains (crystals) on mechanical micromachining processes. The size of material crystals for most engineering materials is comparable to the characteristic scale of mechanical micromachining. Therefore, prediction of the process performance requires capturing the crystallographic effects. The specific research approach includes a blend of experimental and theoretical methods to develop fundamental models for mechanical micromachining processes. The educational objectives of this CAREER plan are to train the next generation of manufacturing engineers, to bring diversity into manufacturing research and education, and to attract K-12 students to manufacturing engineering. The specific approaches involve modernizing the mechanical engineering curricula to include recent advances in micro and nano manufacturing by developing new courses and involving undergraduates in research; collaborating with minority institutions and hiring students from underrepresented groups; and partnering with Pittsburgh city schools to reach K-12 students.If successful, the benefits of this work will be cost-effective manufacturing of high quality, high precision micro parts and miniature devices that will be utilized in medical, biomedical, aerospace, military, national defense, electronics, and consumer products industries. The research results will also enable bringing nanotechnology products to life by bridging the gap between the nano scale and the human scale through comprehensive capability of micro-scale manufacturing. The rapid impact of research to society will be realized by collaborating with industrial companies and government institutions. Since micro-manufacturing is seen as one of the most important areas for the future of manufacturing, this research and educational endeavor will enable retaining and advancing the competitiveness of the United States in manufacturing.

该学院早期职业发展（Career）奖支持工程材料机械微加工的基础研究和教育。机械微加工是指在微尺度上进行铣削、钻孔、车削、磨削等加工的应用。本CAREER计划的研究目标是了解和模拟材料晶粒（晶体）对机械微加工过程的影响。大多数工程材料的材料晶体尺寸与机械微加工的特征尺寸相当。因此，对工艺性能的预测需要捕获晶体学效应。具体的研究方法包括实验和理论方法的混合，以开发机械微加工过程的基本模型。该职业计划的教育目标是培养下一代制造工程师，为制造研究和教育带来多样性，并吸引K-12学生从事制造工程。具体方法包括通过开发新课程和让本科生参与研究，使机械工程课程现代化，包括微纳米制造方面的最新进展；与少数族裔院校合作，聘用来自代表性不足群体的学生；并与匹兹堡市的学校合作，为K-12学生提供服务。如果成功，这项工作的好处将是高质量、高精度的微型零件和微型设备的成本效益制造，将用于医疗、生物医学、航空航天、军事、国防、电子和消费产品行业。该研究成果还将通过微尺度制造的综合能力，弥合纳米尺度与人类尺度之间的差距，使纳米技术产品成为可能。研究对社会的快速影响将通过与工业公司和政府机构的合作来实现。由于微制造被视为未来制造业最重要的领域之一，这项研究和教育努力将有助于保持和提高美国在制造业的竞争力。
