Effect of Servomechanism Characteristics on Accuracy of Contouring Around a Corner

Servomechanism errors in a 2-dimensional contouring system are analyzed to determine the position error of a tool center negotiating a corner formed by two straight lines. The results establish the feed rate which will permit a specified tolerance on path error to be met. Transient response intormation from analog computer tests is summarized in nomographic form to permit convenient consideration of the maximum tool center path error during the design of the servomechanisms.
