Four-point technique development for measuring spherical surfaces of machine parts

Abstract

Abstract The article presents the theoretical foundations of the four-point measurements of spherical surfaces of parts method, allowing to increase the efficiency of spherical structural elements of ball tips of various sizes control. Compared to the measurement method on the coordinate measuring machine, the developed technique can be used at workplaces of forming spherical elements. The technique ensures the efficiency of measurements and increases the efficiency of carrying out the cutting tool settings.
