摘要: 前刀面与后刀面的刃磨加工是球面铣刀加工工艺中最复杂的加工模型,尤其是球面端刃的前后刀面的加工模型,是研究的热点问题.虚轴机床的结构与传统机床不同,机床的运动控制特性也不同,需要特别加以考虑.详细研究了阿基米德螺旋线和圆弧轨迹2种球面端刃前刀面曲线的生成模型,计算了加工这2种前刀面曲线时相应机床运动的位置控制参数,由此提出了适合于虚轴机床的球面铣刀前后刀面刃磨的工艺模型及相应的加工工艺方法,解决了采用6USP虚轴机床加工球面铣刀的工艺问题.使加工模型简化而且合理,提高了虚轴机床的加工效率和精度.

Abstract:   The process to grind ball-end cutter is the most complex in all the tool grinding processes, especial for the rake faces and flank faces of the cutter. They are the research hotspot now. The structure of the virtual axis machine is different from the conventional machine. So its movement control characteristic is different. These characteristic must be taken into account. Two machining models were researched,which were the Archimedes spiral curve and the circle path curve of the ball end cutter rake faces. The position control parameters were calculated when grinding these two curve models. Based on the machining curve model the processing technology was presented according to its special features of the 6UPS machine. The processing technology proposed can simplify the machining model and increase machining efficiency and precision.
