Marco is right, a CNC would make sense for quantity production, or, if you don't make many at once, do you make them over time? I think most CNC systems allow you to keep a program for a pattern. In that case, if you come back after a time to make another one of the same size and shape, you can pull up the code for the pattern, load it and cut it. If you start to use the CNC for very many things, you can build a library of parts, which could save time.
