Description:

Continuation of application filed 05 June, 1956. This application filed 05 Apr., 1963. The present application is a continuation of applicants co-pending application filed 05June, 1956 (and now abandoned).

Claim:

This invention relates to the control of machine tools, and more particularly to controls for machining complex shapes without the need for cams, templates, masters or the like, hut directly from numerical data taken in the first instance from design drawings or specifications. In another sense, the present invention relates to improvements in machine tool control systems of the general type developed by the Servomechanisms Laboratory of Massachusetts Institute of Technology under Contract AF33 (038 )-24007 with the United States Air Force Air Materiel Command and described in "Final Report on Construction and Initial Operation of a Numerically Controlled Milling Machine," Part 1 published 30 July, 1952 and Part 2 published May 31, 1953, by that laboratory.
