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]

Abstract The improvement of ultra-precision machining technology has significantly boosted the demand for the surface quality and surface accuracy of the workpieces to be machined. However, the geometric shapes of workpiece surfaces cannot be adequately manufactured with simple plane, cylindrical, or spherical surfaces because of their different applications in various fields. In this research, a method was proposed to generate tool paths for the machining of complex spherical surfaces based on an ultra-precise five-axis turning and milling machine with a C-Y-Z-X-B structure. Through the proposed tool path generation method, ultra-precise complex spherical surface machining was achieved. First, the complex spherical surface model was modeled and calculated, and then it was combined with the designed model to generate the tool path. Then the tool paths were generated with a numerically controlled (NC) program. Based on an ultra-precision three-coordinate measuring instrument and a white light interferometer, the machining accuracy of a workpiece surface was characterized, and t[1]he effectiveness of the provided tool path generation method was verified. The surface roughness of the machined workpiece was less than 90 nm. Furthermore, the surface roughness within the spherical region appeared to be less than 30 nm. The presented tool path generation method in this research produced ultra-precision spherical complex surfaces. The method could be applied to complex spherical surfaces with other characteristics.
