This Small Business Innovation Research (SBIR)Phase II project will conduct research to develop a new class of cutting tools for high rate/high precision machining of Al-Si alloys, composites, and ceramics. Advanced cutting tools will improve machining economics in the automotive, aerospace and related industries. The new cutters will be made from a patent pending Tricontinuous Diamond/Carbide/Metal Composite (TDCC) material formed using high pressure/high temperature sintering technology. The potential of this TDCC technology was demonstrated in Phase I, wherein proof-of-principle TDCC cutters outperformed conventional PCD cutters and showed up to two times longer tool life in Al-Si alloy machining tests. In Phase II development of the TDCC sintering process will be carried out, with emphasis on demonstrating TDCC tool performance improvement, cost reduction, and quality control applicable for mass production. In addition development and performance demonstration of prototype cutting tools that use TDCC inserts are planned. The primary objective of Phase II research will be to demonstrate the commercial feasibility of making machining tools using TDCC material. Collaboration with a leading automotive parts manufacturer, that will provide facilities and equipment for testing of the TDCC tools, has been arranged. This will help insure that the successful completion of the Phase II effort will lead to Phase III commercialization in the area of high rate / high precision tool manufacturing for automotive and other markets.Use of low wear high impact resistance TDCC tools will significantly impact the automotive and aerospace parts manufacturing industry allowing high transfer line speeds, lower operation count, and better surface finish which in turn will lead to improved production efficiency and lower product cost.

该小型企业创新研究（SBIR）第二阶段项目将进行研究，以开发用于铝硅合金，复合材料和陶瓷的高速/高精度加工的新型切削刀具。 先进的切削刀具将提高汽车、航空航天及相关行业的加工经济性。 新刀具将由正在申请专利的三连续金刚石/碳化物/金属复合材料（TDCC）制成，该材料采用高压/高温烧结技术制成。 这种TDCC技术的潜力在第一阶段得到了证明，其中TDCC刀具的原理证明优于传统的PCD刀具，并且在Al-Si合金加工测试中显示出高达两倍的刀具寿命。 在第二阶段，将进行TDCC烧结工艺的开发，重点是展示TDCC工具性能的改进，成本的降低和适用于大规模生产的质量控制。此外，还计划开发使用TDCC刀片的原型切削刀具并进行性能演示。第二阶段研究的主要目标是证明使用TDCC材料制造加工工具的商业可行性。 已安排与一家领先的汽车零部件制造商合作，该制造商将提供测试TDCC工具的设施和设备。这将有助于确保第二阶段工作的成功完成将导致第三阶段在汽车和其他市场的高速率/高精度工具制造领域的商业化。低磨损高抗冲击TDCC工具的使用将显著影响汽车和航空航天零件制造业，从而实现高传输线速度，降低操作次数，以及更好的表面光洁度，这又将导致提高的生产效率和降低的产品成本。
