The tweeting machine – CNC-PLC interface

The development and use of computerized machining tools and equipment within the manufacturing area has opened the door to an abundance of data. But, there is a need to structure the data, make it generic and accessible and define ways of communication in order to maximize the benefits of its utilization. The Line Information System Architecture (LISA) project aims to create an information architecture which aids in capturing and understanding this data by tackling the above mentioned requirements.This thesis is intended to implement the Tweeting machine concept, tweeting useful machining information during operations. The data will be transferred to the LISA architecture, providing users with the possibility to subscribe to the information. Offering useful and structured real-time data, which can be used to e.g. aid in analyzing and decreasing processing flaws, increasing quality, decision making. The solution has been tested and verified using transport communication protocol (TCP) and open communication protocol (OPC) connections. Which have been applied to the 5-axis machining tool HERMLE C 50 U, in the Department of Production Engineering at the Royale Institute of Technology, Stockholm, Sweden.The thesis report will firstly provide the reader with necessary background information regarding the computerized numerical control (CNC) machine used as well as its configuration. Followed by information regarding OPC, TCP and Industrial Ethernet as well as a run through of the operational software used. The programming of the solution is provided in a relatively detailed manner with the hopes that it will provide a good basis for future development of this implementation
