CNC contour cutting with/without an incision

This machine cuts the foam into a certain shape on the basis of a program / drawing.  This can occur on a CNC controlled machine with a rotating saw, which has the advantage that several pieces are sawed simultaneously. A possible disadvantage is an incision from the outer to the inner contour. If this incision is a problem, the plotter (contour machine with a blade) can be opted for. Both machines work on the basis of a program so that a prototype can quickly be made.
