Powermill在五轴机床加工轮胎模具中的应用

Application of Powermill on the tire mold of five-axis machine

传统的立式加工中心三轴联动加工的应用是最为广泛的加工方式，刀具始终处于立式状态，球头铣刀切削点的切削速度无法得到优化处理，那么单纯的三轴立式加工已无法满足当令加工的飞速发展。所以5轴联动高速加工机床应境而生！五轴加工适用于复杂、工序多、精度要求高、需用多种类型普通机床和繁多刀具、工装，经过多次装夹和调整才能完成加工的具有适当批量的零件。如：汽车的发动机缸体、变速箱体，机床的床头箱、主轴箱，柴油机缸体，齿轮泵壳体，轮胎，叶轮，螺旋桨、各种曲面成型模具等，本文针对五轴加工技术的特点，论述了powerMill软件的五轴加工功能和五轴的刀路轨迹策略。通过轮胎模具加工为实例，来介绍五轴加工的具体应用及特点。

Three-axis simultaneous machining via traditional vertical machining center is the most widely-used processing method. The tool is always in the vertical state and the cutting speed at cutting point of the ball-end mill can＇ t be optimized, which make the simple three-axis vertical machining can＇ t meet the today＇s rapid development of machining. Therefore, five-axis simultaneous machine emerges! Five-axis machining is suitable for appropriate quantity of parts, which are complex, require multiple processes, high precision, multiple types of common machines and many tools, tooling. The machining can only be completed after multiple setup and adjustments, such as cylinder body of automotive engine, gearbox body, headstock on the machine, spindle box, cylinder body of the diesel engine, shell of the gear pump, tire, impeller, propeller and various types of curved surface forming mold. Aiming at the feasures of five-axis machining technology, this article discusses five-axis machining function and strategy for five-axis tool path, takes machining for the tire mold as an example to introduce specific applications and features of five-axis machining.
