Doug- given that stylus rake angle is such a well accepted theory somebody must have done this already. With far more accuracy than I can. From what I have gathered so far the head is more like a plow than a knife. It cuts forward and to the side. The cutting head digs down into the vinyl cutting ahead and side to side. The master is rotating underneath the head.
To further complicate matters the cutting is now being heated. This means that there is some melting going on. The articles all swear by SRA again providing no proof.
