Sommario/riassunto |
|
In machine tools, the designed systems include many components, such as sensors, actuators, joints and motors. It is required that all |
|
|
|
|
|
|
|
|
|
|
these components work properly to ensure safety. This book examines fault monitoring and control schemes in machine systems, as well as detecting machines whenever a failure occurs and accommodating the failures as soon as possible. Also discussed are centre-less grinding machines; improving machine tool performance through structural and process dynamics modelling and exploring the strength of the Japanese machine tool industry. |
