The concept of swept sections for flat-ended tools is revisited with the goal of improving the accuracy of calculations in five-axis tool path generation. Firstly, the notions of partial and total swept sections (distinct from traditional swept sections) are introduced. It is shown that partial and total swept sections provide a more accurate representation of the geometry of the moving tool compared to traditional swept sections. Next, geometric and numerical methods focused on calculating partial swept sections are presented. These methods are based on calculating plane-circle intersections. Finally, the calculated partial swept sections are compared to the traditional swept sections. Variations from the traditional swept sections are characterized to provide guidelines to the tool path programmer. [S1087-1357(00)71101-4]

The Relationship

A algorithm of interference free tool path generation for 5-axis NC machining with flat end cutter is presented. The approach includes: To obtain cutter location points from cutter contact points; interference pretreatment by convex box of NURBS surfaces and reducing check area; interference detection and tool-position correction based on mesh model while the interference problem is substituted with the relationship between tool and triangles. The algorithm is speed and reliable.
