【摘要】 异型螺杆在一些行业用途极其广泛,而且其加工方法与普通零件有所不同。本文中提出了一种加工螺杆螺旋槽数控编程新方法,即根据求出的螺旋面加工刀位点做螺旋运动来实现螺旋面的加工,该方法既可以加工直线槽螺杆,也可以加工曲线槽螺杆。文中对螺杆加工工艺和机床要求进行了介绍,对螺旋面加工刀位点计算、数控编程、走刀方式、走刀步长确定、走刀行距计算进行了研究。并通过实例验证所述方法实用有效。更多还原

【Abstract】 Special shaped-screw is widely used in some industries,and the machining process is different from most normal parts.A new method of numerical control(NC)programming to machine screw is proposed,in which the screw face is cut by cutter moving through screw curve track.The method can be used in machining screw with line-shaped groove and curve-shaped groove.Screw process and machining tools are introduced.Computing coordinates of cutter location points,NC programming,cutting method,Computing tool step,and Computing stepover length are researched.The application results verify the validity of the present techniques.更多还原
