Patent ID: 7890292

Claim:
A method for measuring the diameter of a circular track on a component, this method comprising: a) a step for moving the component along a measurement trajectory, b) when the component is moved along the measurement trajectory, a step for measuring, without contact with the component, at least one quantity that is a function of the diameter of the circular track, c) a step for determining the diameter of the circular track based on the quantities measured at several measurement points along the measurement trajectory, wherein the step a) is carried out by means of a robot formed from a fixed base and from a manipulator arm articulated about at least two axes, the end of the manipulator arm being equipped with a gripping mechanism capable of grasping and holding the component, and in that, during the step a), the robot moves the component in a continuous manner with an instantaneous speed which is never zero along the measurement trajectory and an instantaneous acceleration which never changes sign along the measurement trajectory.
