9313162这项研究是为了研究高速薄片铣削淬火钢的机理，同时考虑高压冷却液的影响。研究内容还包括研究最合适的刀具几何形状、球头薄片铣削的颤振和共振理论、力和振动的仿真软件、机床和主轴设计的改进、相应的数控策略软件，以及该技术的演示和经济评价。这项研究有望就高速加工模具的加工条件、刀具、刀架、主轴、机床和编程考虑因素提出建议。预计生产率和表面光洁度将好于目前的电火花加工技术，并有望使模具制造业受益。

9313162 Tlusty The research is for investigation of the mechanics of high- speed, thin-chip milling of hardened steels, taking into consideration the effects of high pressure coolants. The research also involves investigation of the most suitable tool geometry, a theory of chatter and of resonant vibrations for ball-nose thin- chip milling, simulation software for forces and vibrations, improvements in machine tool and spindle design, software for the corresponding strategies of numerical control, and demonstration and economic evaluation of this technology. The research is expected to result in recommendations concerning machining conditions, tools, tool holders, spindles, machine tools, and programming considerations for high speed machining of dies. The productivity rates and surface finish are expected to be better than those achievable by current electro- discharge machining technology, and are expected to benefit the die manufacturing industry.
