A new generation of machine tools are to be developed to be parts of Industry 4.0 production systems. Machine Tool 4.0 will be CyberPhysical Machine Tool (CPMT) and it will be a key component of CPPS.
The proposed CPMT consists of four main components:
(1) CNC Machine Tool, (2) Data Acquisition Devices,
(3)Machine Tool Cyber Twin (MTCT), and
(4) Smart Human Machine Interfaces (HMIs).
MTCT comprises four main components:
a) Information Model,
b) Database,
c) Intelligent Algorithms and Analytics, and
d) Machine-to-Machine (M2M) Interfaces.
x The Information Model comprehensively represents both the structure of the machine tool and the real-time status of each critical component by taking full advantage of the real-time data coming from the Data Acquisition Devices.
x The Database records all the important historical information of the machine tool, making it available for further analysis both locally and in the cloud.
x Intelligent algorithms and analytics transform the data coming from Data Acquisition Devices into meaningful information and offer various intelligent and autonomous functions, such as Prognostics and Health Management (PHM), machining optimization and Augmented Reality (AR)-assisted process visualization. Intelligent algorithms and analytics make the machine tool more adaptive to the changing machining conditions.
x M2M Interfaces allow the MTCT to semantically
communicate with the Cyber Twins of other field-level
devices (robots, AGVs, workpieces, etc.). Embedded
algorithms enable the physical objects in the
manufacturing system to monitor and control each other,
leading towards an autonomous-cooperative manufacturing
environment.
