Intelligent machining systems enable to adapt to the changes of manufacturing environment such as orders, disturbances happening in the system. In machining system, machine tools play an important role to have the products with high quality, low cost and high productivity. The paper presents a new concept of intelligent machining system, namely Autonomous Machining System- AMS. | Vietnam Journal of Science and Technology 55 (3) (2017) 368-381 DOI: AUTONOMOUS MACHINING SYSTEMS Tran Ngoc Hien Faculty of Mechanical Engineering, University of Transport and Communications, Cau Giay Street, Lang Thuong Ward, Dong Da District, Hanoi, Vietnam Email: ulsanuni@ Received: 20 August 2016; Accepted for publication: 20 February 2017 ABSTRACT Intelligent machining systems enable to adapt to the changes of manufacturing environment such as orders, disturbances happening in the system. In machining system, machine tools play an important role to have the products with high quality, low cost and high productivity. The paper presents a new concept of intelligent machining system, namely Autonomous Machining System- AMS. Biology inspired technologies are applied to the machine tools for equipping these machines with biological characteristics such as self-diagnostic, self-recovery, and cooperation. With these advanced characteristics, AMS has ability to adapt to changes on the shop floor. Keywords: autonomous machining system, artificial intelligence, cognitive agent. 1. INTRODUCTION In traditional manufacturing systems, the workers play an important role, with their knowledge and experience, the workers adapt flexibly to changes in the manufacturing environment. With new problems, their knowledge is updated through learning [1]. With abilities in processing information and cognitive abilities, the workers keep an important role in monitoring, control, production planning. The workers with the ability to solve problems and cognitive capacity enable to adapt with changing manufacturing environment. However, the system manipulated by workers with a high price is only suitable for small production. In the era of computer integrated manufacturing, workers are replaced by automatic control systems and robots, so the cognitive abilities of workers in solving problems such as perception, learning, reasoning for a decision .
