摘　　要：基于刀具与螺旋面工件之间的关系及基本加工原理,提出了一种新的基于离散点的圆柱螺旋面成形刀具廓形的CAD生成方法——薄片法。采用VB对SolidW orks进行二次开发给出了薄片法的实现程序,并与CAD实体布尔运算法进行了比较。结果表明:该方法不仅精度高,而且具有直观、简单,内存占用小,生成文件小等优点。A new CAD method—slicemethod calculation on discrete points of forming shape tool for cylindrical helicoids was presented,which was based on analysising the relationship between spiral workpiece and the tool and studying the basic principle of tool cutting process.The method was implemented by using SolidWorks and VB.Comparing with CAD entity Boolean operation method,The result shows that the presented method not only has the high-accuracy but also the advantages of visualization,simplicity,small demand in imternal storage and so on.
