Computerized Inspection of Real Surfaces and Minimization of Their Deviations

Abstract

A method is developed for the minimization of gear tooth surface deviations between theoretical and real surfaces to improve the precision of surface manufacture. Coordinate measurement machinery is used to determine a grid of surface coordinates. Theoretical calculations are made for the grid points. A least square method is used to minimize the deviations between real and theoretical surfaces by altering the manufacturing machine-tool settings. An example is given for a hypoid gear.
