The influence of workpiece eccentricity on machining accuracy during turning

Turning processing;  eccentricity;  Machining accuracy

Aiming at the problem that the curve machined by the workpiece under eccentricity is a circle or a heart-shaped line, the influence of workpiece eccentricity on the position accuracy and shape accuracy of the machined surface is analyzed, and it is pointed out that in the turning process, the eccentricity of the workpiece will cause the coaxiality position error between the machined surface (outer circle or hole) and the shape error of the roundness and cylindricality of the machined surface. The machined surface is neither a circle nor a heart-shaped line. Therefore, it provides an important theoretical basis for improving the accuracy of turning machining.
