摘　　要：研究非球面中较为常见的双曲面,采用坐标变换方法,针对刀具右倾、左倾和铅垂方向三种姿态,分别建立加工双曲面的数学模型。分析工件参数、刀具参数、刀具切削状态参数以及机床构型参数之间的函数关系,从而推导刀具位于铅垂方向的位置、双曲面的矢高和口径等关键技术指标的变化规律,基于此推演不同姿态下双曲面最大矢高和最大口径,从而明确了保证无干涉现象的双曲面加工范围。这里的方法与结论为加工双曲面的参数选取提供参考。The hyperboloidal surface was studied,which is common in aspheric surface.The tool could be inclined to the right,the left and vertical,therefore the mathematical model for machining hyperboloidal surface was set up by coordinate transformation method.The functional relationship between workpiece parameter,tool parameter,tool cutting state parameter and machine tool configuration parameter was analyzed.The variation law of key technical indexes such as the position of tool locating in vertical direction,the vector height and aperture of hyperboloidal surface was investigated.The maximum vector height and aperture of hyperboloidal surface was deduced.The dimensional range for machining hyperboloidal surface based on no interference was clarified.The method and results facilitated the parameter selection for machining hyperboloidal surface.
