Abstract
AbstractIn freeform surface measurement, the measurement accuracy is partially governed by the density of measuring points. Making a uniformly dense sampling is a very time consuming measurement process. This paper presents a Segment Based Freeform Surface Algorithm for selecting the measuring point that will convert the section of surface to two-dimensional curves. Tolerance specification, degree of change of curvature, and machining condition are the parameters used to define the measuring point selection in different areas of the part’s surface under measurement. This process will establish the optimized solution to generate the sampling points for a CMM measurement program, to save the measuring time and improve the quality control of the final product
