The Influence of the Mechanical Deformations on the Machining Accuracy of Complex Profiles on CNC Lathes

In this paper, the problem of accuracy control of machined complex profiles is investigated. Presented are schemes of the mechanical load of the cutting tool as a function of the current angle of the machined profile. A simple method for compensating the profile error caused by mechanical deformations is suggested. Presented is an algorithm for the automatic measurement of the machined profile and for the compensation of the profile error.
