PAGE  PAGE ２１ 摘 要 目前采用数控加工是解决该类零件圆弧曲面、锥面和高精要求圆柱面最有效的加工方法，小圆头轴是轴类零件中比较复杂的一种零件，是连接或转换的关键部件，也是较难加工的零件。数控加工工艺制定和编程是实现其高精度和高效率加工的重要环节。小圆头轴数控加工中涉及到零件图样工艺分析、加工方法和加工顺序的确定、装夹方案和夹具的选择、选择刀具及确定切削用量等关键技术。通过对这些技术的链接和研究，完成小圆头轴数控加工。 关键词 小圆轴 数控加工工艺 编程 Abstract The axis is in the axis class components model, Is the energy conversion key component, Also is the components which more difficult to process, At present uses the numerical control processing is solves this kindof components circular arc camber, the conical surface and Gao Jingrequests the round cylinder most effective processing method. Thenumerical control processing craft formulation and the programming arerealizes its high accuracy and the high efficiency processingimportant link. This article introduced in the axis numerical controlprocessing involves to the components pattern craft analysis, theprocessing method and the processing order determination, the attireclamps the plan and the jig choice, chooses the cutting tool and thedetermination cutting specifications and so on the essentialtechnology. Through to these technical links and the research,completes the axis numerical control processing.
