Abstract
To determine the reproduction error of a trimming machine associated with a contour follower device, a first reading is taken on the contour follower device from a template of known shape. A part is then machined on the trimming machine in accordance with the first reading. A second reading is taken on the contour follower device using the machined part. The reproduction error is deduced from the two readings by calculation. The method can be applied to autocalibration of a system comprising a trimming machine and a contour follower device associated with each other by way of a numerical controller, in particular for machining an eyeglass lens.
