UG CAM 中 Planar_Mill 有关毛坯参数的设置

UG CAM 软件中 Planar_Mill 是一种常用的数控加工方法，其中，毛坯参数的设置将会直接影响刀具轨迹的形成。毛坯参数的设置包括创建几何体毛坯、毛坯边界、毛坯距离和毛坯余量。对毛坯参数的设置方法进行了阐述和比较，对几种参数的具体应用场合和应用技巧进行了详细的说明，并选取典型实例进行了应用示范，从而使得毛坯参数有效地服务于数控加工。

Blank Parameters Settings in UG CAM Planar_mill

Planar_mill is a commonly methods used when NC machining in the UG CAM.In the design,the related pa-rameters of blank directly affect the formation of tool path.The blank parameter setting has the following kinds：creating geometry blank,blank boundary,blank distance and blank allowance.In the paper,explained and compared the blank pa-rameter setting,and also explained specific applications and application techniques of several parameters in details.Finally, a example was used in application.The main purpose of this paper was to make readers to better understand the meaning of parameters of blank,so that these parameters can serve the NC machining effectively.
