CNC cutting

CNC (Computer Numeric Control) machine are more and more common. For example, companies making signalling panels are frequently equipped. This allows a boat-builder, amateur or professional, to sub-contract the cutting to a local company. This may be very useful in countries or areas where I have not any cutting partner. For that purpose, I am now selling CNC files for many boats. These files, (dxf format) are readable by all CAD software. I have made them in order to be compatible with most CNC machine. Therefore, it is not frequent to get technical troubles. If any, I will try to modify the files, and, if unsuccessful, I will refund the files price.

There are several cutting techniques: mechanical routers, laser or water jet. I prefer the mechanical routers. Laser burns the plywood edges and may reduce the epoxy adherence. Water jet wet the plywood and, if the parts are stacked not fully dry, may cause damages. The files are generally made for a maximum 8 mm tool diameter. As a rule, nesting of parts is made into 2.44 x 1.22 m (8′ x 4′) panels, which is the most common size in the world.
