Machine tools can be controlled automatically by precisely programmed commands encoded on a storage medium. This kind of control is called numerical control. In this paper, a typical position control machine tool system required to automatically drill a number of holes is considered. It is required that a controller is designed to enable the system achieve stated specification.


Control of machine tools is a relatively new field that started in the early 1950s with the invention of the Numerically Controlled (NC) machine tool by John Parsons in Traverse City, MI, with subcontract to the MIT Servomechanism Laboratory [6].The major advance in NC occurred in the early 1970's with the introduction of Computer Numerical Control (CNC) in which a dedicated computer replaced most of the digital hardware control boards of the NC. Approximately at the same time, a few companies (e.g., Bendix [7]) started to develop adaptive control (AC) systems for machine tools. One of the early CNC/AC machines, developed by J. Tlusty and Y. Koren in 1973 [8], utilized an HP-2100 computer as the controller that runs both the conventional CNC and the AC programs.
