DISPOSITIF DE SAISIE ET D'AFFICHAGE POUR RECTIFIEUSE A COMMANDE NUMERIQUE

摘要

An interactive data input device for a numerical control grinding machine is provided with a key board for inputting data which defines the shapes of a number of machining portions formed on a cylindrical workpiece and a central processing unit for controlling a display controller to display on a screen of a cathode ray tube (CRT) display unit the profile as taken along the workpiece axis, of each machining portion based upon the shape data input by the key board. The central processing unit is programmed to display, in addition to the profiles of the machining portions, the profile of a non-machining portion formed between two machining portions based upon the shape data for the two machining portions.
