    Abstract: The invention relates to a process and an apparatus for positioning a point belonging to the cutting zone of a tool in a digitally controlled lathe.The process consists of obtaining the image of the contact point of the tool cutting zone in a virtual relative mark with two perpendicular axes and then bringing about coincidence between the origin of the relative mark and the rotation axis of the tool holder capstan.
