Abstract
The absolute positioning accuracy of a motion control system is, making abstraction of errors induced by imperfections of the transmission, completely determined by the positioning accuracy of the individual actuators. Accurate contouring additionally requires high degrees of synchronisation between actuators. Indeed, the superposition of two orthogonal and sinusoidal movements only results in a perfect circle if both have exactly the same frequency and if they are out of phase by exactly ninety degrees.
