From digital drawing to computer-controlled machining — and why craftsmanship is still crucial
Where the carpenter previously shaped everything by hand with saw, plane and chisel, an increasingly large part of production today is computer-controlled. It has not made the craft obsolete, but it has changed how many tasks are solved from drawing board to finished item.
CAD (Computer-Aided Design) is the digital design drawing of the part. CAM (Computer-Aided Manufacturing) takes the digital drawing and converts it into tool paths — the actual movements a production machine must make to manufacture the part.
IT and CAD/CAM are included as part of the training-specific subjects in the main course for carpenter, along with design, form, construction and energy understanding. The CNC/machine carpenter training has an even more marked focus on CNC technology and robot use in the industrial part of the wood trade.
A CNC machine is strong at repetitive, standardized tasks, but the final adjustment on the building site, assembly and finish often require craftsmanship assessment that no machine can replace. A workpiece cut perfectly on a CNC machine must still be adjusted to the actual conditions when it is to be mounted in a crooked and older building.
Digitalization changes work processes and places new demands on IT and CAD/CAM skills for the modern building carpenter. But it does not replace the need for craft understanding — rather it shifts focus so the carpenter's experience is increasingly used for adaptation quality assurance and tasks that can never be fully standardized.
