Based on analyzing the existing algorithms, a novel tool path generation of 2D contour considering stock boundary is presented. Firstly the boundary points of stock are obtained by three-dimensional measuring machine. And the boundary curve is constructed by method of features identifying. The stock boundary is offset toward outside with tool diameter. An enclosed region is formed between the contour curves and the offset curves of stock boundary. The tool path is generated by form of parallel spiral by offsetting the stock boundary in the enclosed region. Finally the validity of present method is demonstrated by an example.

Five Axis

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.
