The Foundation of Modern Automation: Yoram Koren’s Computer Control of Manufacturing Systems First published in 1983, Computer Control of Manufacturing Systems Professor Yoram Koren
Detailed analysis of interpolators , control loops , and computer algorithms .
The book covers a wide range of topics, including:
The book explores the evolution from early hardware-based systems to modern Computerized Numerical Control (CNC) , emphasizing its flexibility and cost-effectiveness compared to Direct Numerical Control (DNC).
Koren’s text provides the definitive breakdown of Computer Numerical Control (CNC) architecture. Unlike earlier texts that focused on the punch-tape inputs of NC (Numerical Control) machines, Koren focused on the computer interface. He detailed the structure of the CNC controller, the role of the central processing unit (CPU), and the input/output channels. For engineers searching for a PDF of this work, this section is often the primary target—it provides the schematic understanding required to diagnose and repair legacy and modern machines alike.
The heart of any automated machine is the servo system. Koren’s book bridges the gap between control theory and manufacturing application. He explains the dynamics of the feedback loop—how encoders and tachometers feed data back to the controller to correct errors. He famously analyzes the "following error" in velocity control, a concept that remains critical in high-speed machining today. If a machine tool lags behind its programmed position, it can scrap a part; Koren provides the mathematical tools to predict and minimize this lag.
