dc.description.abstract Development of Smart Factories (SF) renders an incredible opportunity for the manufacturing industry to join the fourth industrial revolution (Industry 4.0). With use of Digital Twin (DT), Edge Computing (EC), Machine Learning (ML) concepts and being part of a whole as interconnected Internet of Things (IoT) SF can collect and analyse data from sensors and embedded software for better decision making, real-time visibility of manufacturing assets and predictive maintenance in order to minimize machinery downtime. Many manufacturing plants still operate conventional machines with a Computer Numerical Control (CNC) which blindly execute given programmed instructions. Such machines usually can be connected to a network only for uploading these instructions and some machine parameters into the machine. The instructions or programs consist of G-code and M-code sequences and must be generated for every machine model and for each processed component individually prior to manufacturing. As part of the move towards SF it is vital to use a control language with the ability to carry more product related data compared to G-code and M-code language. Standard for the Exchange of Product data compliant Numerical Control (STEP-NC) addresses these concerns. STEP-NC links process data to a product description of the manufactured component. During these transitional times then not every piece of equipment supports features of the SF especially conventional CNC machines which are widespread and still in use, but the lack of the cyber features prevents them from being integrated into a SF. It is becoming more vivid to find ways to convert a conventional CNC machine into a Cyber-Physical Machine Tool (CPMT) compatible with requirements of Industry 4.0. With current achievements of the open-source community, level of network technologies and availability of electronics, minimal investments required to transform a conventional CNC machine into CPMT with a highly configurable system tailored to needs of a SF. Developed framework provides network integration for a CNC machine and uses a bypass of conventional CNC controller’s workflow to establish a Smart Numerical Control (SNC). SNC is a dispersed network system that can control more than one CNC machine and modify toolpath being executed in near realtime manner for closed loop manufacturing with no need for G-code. The SNC provides sensors data management and an interface to control these CNC machines with other software, for example by obtaining a toolpath from a STEP-NC file.
