【摘要】 根据成形车刀的设计理论,综合运用UG/OpenMenuScript、UG/Open UIStyler、UG/Open API和VisualC++6.0等UG二次开发工具,开发出了基于WindowsXP和UG二次开发平台、以VC为编程工具的成形车刀CAD系统。该系统利用自动截形法获得成形车刀"零误差"刀刃廓形;利用最小半径控制点技术实现了圆体成形车刀的基于特征参数化设计;使用数据库技术实现成形车刀的切削角度、结构尺寸的参数化设计;编程实现了工程图的尺寸标注功能及圆体成形车刀剖视图的建立;解决了原来成形车刀设计的设计精度和效率低等问题。借助该系统可直接快速、准确地生成高精度圆体成形车刀工程图以及廓形的数控车床加工程序。更多还原

【Abstract】 A CAD system of formed turning tools is developed by the use of UG/Open Menu-Script,UG/Open UIStyler,UG/Open API and Visual C++6.0,which regards Windows system and UG as a platform according to formed turning tools design theory.This system utilizes the method of intersecting work-piece automatically to obtain zero error intersection of the tools edge.Utilizing the technique of minimum radius control point,which realizes parametric design based on feature on circular-formed turning tools.Cutting angle,parameters of structure dimension are designed by the use of database technique,and the realization of dimension-driven function and the section view of the circular-formed turning tools by means of system programming.This method solves the problem of the tools former design,such as low design precision and efficiency,etc,and eliminates the hyperbolic errors.This system can quickly,directly and accurately makes not only the detail drawing of high precision circular-formed turning tools,but also the NC program of NC Lathe of the tool profiles.更多还原
