Paper Abstract

The tool path generation based on iso-phote is a kind of feature based path generation method. Iso-phote curves represent the characteristic curves on a parametric surface. Accordingly, iso-phote based tool paths has been proposed as an important path pattern for parametric surface machining. An adaptive interpolation method for tool path generation based on iso-phote interpolation for wedge/aspheric lens element grinding was proposed, which takes into account the symmetry problem of wedge/aspheric process behavior. This paper presents an efficient interpolation method for tool path generation approach based on iso-phote curves and bisection method. By the application of parallel grinding, the approach can guarantee the feature of aspheric lens, maximize machining speed and smooth the machine operation for high surface quality. The interpolation method guarantees that step length of the interpolated points always keep the precision. The method can improve and automate large scale wedge/aspheric lens element grinding for 3-axis CAD/CAM systems. As part of the validation process, the tool paths generated and interpolation error are analyzed and compare with the traditional method.
