Manufacturing of the prefabricated wooden house vastly depends on craft manufacturing. The level of automation in this sector shallow compared to other branches of industries. One reason is with high flexible production where traditional industrial automation with centralized, programmable logic control is not adequate. Skilled workers are still responsible for machining operations like nailing, crewing, drilling, etc. One approach uses a configurable multi agent system (C-MAS) to automate the production, where one or several robots work together collectively and collaboratively. C-MAS does not use any centralized control system, instead uses distributed control agents, making it possible to reduce the downtime during the changeover. But the geometry information from the external sources is neededto support Plug & Produce. A script-based CAD software, FreeCAD is used to build the workbenches of the machining operations and export the geometry information in JSON format to the SQL data server from the depicted CAD model of the prefabricated wooden wall.
