The construction industry has constantly been researching and looking forimprovements, and off-site construction has been one of the leading areas due to itsadvantages in controlled stations. A common material in off-site construction has beenCross-Laminated Timber (CLT) due to its sustainability, and programs like BIM nowinclude this option for the developers. However, there is a lack of manufacturabilityfeedback in the BIM model, and domain experts must be involved to define themachining and process planning. Therefore, this research develops in the machiningautomation of Cross-Laminated Timber in a robotic cell and target-path planning. Frist,an analysis is implemented to understand the areas of opportunity for manufacturingfor CLT. The analysis was scientometric, comparing two research fields, constructionin CLT and Industry 4.0. This review found two gaps: a digital twin or machiningstation for CLT and the automation of its programing. Second, once the need for adigital twin or machining station was found, its development was implemented in avirtual station based in RobotStudio. This machining cell makes use of industrial robotswith an additional external axis and a flexible clamping station. This station is validatedvirtually with a CLT panel as a case study where its programming is done manually.Finally, as the station is ready to accept the programming for the machining of CLTpanels, a target-path planning algorithm was developed. This algorithm processes theentire case study CLT panel and automatically detects the primitive geometries withthe need for machining. Depending on the geometry and dimension, the algorithmcreates a sequence of targets and assigns the robot and tool required for its machining.
