A practical method of modelling and simulation for drill fluting

A grinding wheel profile for drill fluting is usually designed by the indirect method, defining the wheel profile by the desired drill flute. This paper presents an adaptive and intuitive direct method for drill flute modelling. It is summarized as follows: the grinding wheel, with analytically defined profile, is assumed to be moving helically around the stationary drill; the flute is generated by the overlapping part between the wheel locus and the workpiece. Its validity is verified by good agreement between the results computed and the data measured on the samples manufactured.
