Simulation modeling of turning of ring workpiece which is located on machining surface

Simulation model of ring work piece turning is offered. The work piece has radial section inaccuracy as ellipse. The work piece is located on machining surface. Single point cutting tool has vertical feed motion to work piece. It is considered that there is free orthogonal cutting. Calculation with work piece diameter 300 mm show that under specified conditions it is possible to increase ellipticity from 0, 5 mm to micrometers.
