This is an era of Industry 4.0. The IoT is the core technology of Industry 4.0, which tags information such as the shape, position, property and history of all things including human beings and manages them in real time by connecting them with the Internet. Being tagged and connected with the Internet by the Radio Frequency Identification Device (RFID), all things are in real-time Smart management.
If the spindle unit which is the core unit of a machine tool is in real-time management through the Internet by introducing Internet of Things (IoT) from the design stage, the quality of design can be further improved and put on a scientific basis.
Kim Son Ho, a researcher at the Faculty of Mechanical Science and Technology, defined the tag content of machine parts, tagged spindle unit parts of "RT-350" CNC lathe and introduced a 3D modeling algorithm for them. In addition, he programmatically implemented an RFID by identifying the shape, position, property and history information of the parts using the IF-THEN-module of rule-based reasoning (RBR) of the expert system.
As a result, the design quality of a spindle unit has further increased and the time for design has been reduced by 1/5. In addition, the design has become more intelligent.
