Abstract: A customer transmits their 3D CAD file for a part to be total profile machined. Computer analysis of the transmitted CAD file produces CNC machining instructions, which are transmitted back to an address defined by the customer. The customer can then use the transmitted CNC machining instructions to total profile machine their own part using their own CNC mill at the location where the part is likely needed. The transmitted instructions include not only the tool paths for CNC machining of the total profile of the part, but also for additional features formed into the encircling portion of a material block from which the part is to be total profile machined. For instance, the CNC machining instructions transmitted back to the customer can define a registration recess and/or channels or undercuts for fluid support material on an A-side of a material block. After the A-side of the block is machined, the customer adds and solidifies fluid support material into the machined recess.
