A new regulating, wheel truing method for through-feed centerless grinding
is presented. In conventional regulating wheel truing systems, a single-poi
nt diamond tool is traversed across the regulating wheel in a straight line
. The interference between the regulating M heel and workpiece exists. This
interference problem, a main source of Error in precision through-feed cen
terless grinding, is due to the radius of curvature of the regulating wheel
and workpiece. A new concept for regulating wheel truing is developed to e
liminate the interference a problem. In this new. truing system, the rotary
diamond truing tool has the same size as the finished workpiece, locates a
t the same center-height of the workpiece, and moves across the regulating
wheel in the direction parallel to axes of workpiece and grinding wheel. A
mathematical model is developed to calculate the surface profile for the re
gulating contact and to study the curved line of contact between, workpiece
and regulating wheel. An example is used to illustrate the model and to de
monstrate that the interference between regulating wheel and workpiece has
been eliminated.
