Abstract
In machining parts and especially optical lenses by means of a model, a single model having a shape which is the reverse of that of the part to be obtained is used for all of the various machining operations. In the machining operations, on the one hand, the model is coupled with the tool which machines the part and, on the other hand, the part to be machined is coupled with a feeler which is in contact with the model.
