Modeling of Color Design on Furniture Surfaces with CNC Laser Modification

Today, handcrafted furniture surface treatment techniques are less used due to application difficulties and high costs. Recently, the use of CNC router processing machines has resulted in a revival of these techniques. However, since this method is insufficient in micro-processes and color modifications that require precision, these processes have started to be performed with lasers. In this research, the beech wood surface was processed using a CNC laser processing machine with a carbon dioxide gas tube by applying different engraving power and engraving speeds. Product design and manufacturing parameters were determined in the CIE L*a*b* color system using the regression modeling method. A sample application was made by applying laser engraving to a furniture surface designed according to the obtained parameters. As a result of the study, it has been explained that using L* color group regression modeling method and CAD/CAM supported laser technology in furniture top surface color design processes is suitable for industrial engineering approach. It has been determined that many surface color design techniques can be applied with laser to furniture designed for CNC laser production.
