驱动式滚切铣削机理分析及其刀具

为了对驱动式滚切铣削及驱动式滚切铣刀进行深入研究，在充分分析滚切加工特点的基础上，提出了以滚切速率比表征滚压和切削的比例关系，结合滚切速率比对驱动式滚切铣削的加工表面质量、刀具后刀面接触滑动速率、驱动式滚切铣削的铣削力的机理进行了研究。得出了驱动式滚切铣削本身特有的切削规律，并依据这些规律提出了驱动式滚切铣削加工的硬件实现形式“内驱动式滚切铣刀”。结果表明：内驱动式滚切铣刀(又称难加工材料专用铣刀)既能够根据待优化参数的要求在机加工前调节滚切速率比的值，又能够在机加工过程中保持调节好的滚切速率比的值稳定，相对传统的自滚切刀具具有很强的优势。

Rotary Tool Milling Processes and Its Tool

Rotary tool cutting process is applied to cutting especially in difficult-to-cut materials cutting with its unique advantages. There is no literature about it. The rotary rate ratio that is the proportional relationship of “rolling” and “cutting” was presented for the first time based on analysis of rotary tool cutting processes was. Combined with the rotary rate ratio, machined surface quality and the contact sliding rate and milling force were studied. An inner driving rotary milling tool was first proposed in this paper. It is the hardware realization of the driving rotary milling tool. The rotary rate ratio of inner driving rotary milling tool not only can be adjusted before cutting processes in accordance with the requirements of parameters, but also can keep the adjusted value in machining process. Results show that the inner driving rotary milling tool has a strong advantage, compared with the traditional self-propelled rotary tool.
