A customer sends a CAD file for the part to be manufactured to the system. The system assesses the CAD file to determine various pieces of manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be machined in two opposing orientations in a 3 axis CNC machine. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities or parts per workpiece block, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts, which may include both molded parts and total profiled machined parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer. Interactivity is also achieved, with the customer being able to modify the quotation interactively by modifying one or more of the initially selected parameters, including selecting a different budgeted amount.

1. A method of automated, custom manufacture of a part, the method comprising: creating a collection of stored information of material removal steps to transform a block of material into a custom part;receiving a CAD file over a global communications network from a customer for the part, the CAD file defining a part surface profile;processing the received CAD file to identify and locate discrete portions of the part surface profile, each discrete portion corresponding to one material removal step from within the collection of stored information, wherein the identified discrete portions of the part surface profile include at least a first discrete portion accessed from a first side of the block of material by a CNC machine and a second discrete portion accessed from a second side of the block of material by the CNC machine after the block of material has been reoriented relative to the CNC machine;generating a quotation based upon the identified and located material removal steps; andtransmitting the generated quotation to the customer over the global communications network. 2. The method of claim 1, further comprising providing the customer with at least one menu of customer-selectable values for a cost-affecting parameter of manufacture, wherein the menu is provided over the internet and the generated quotation is transmitted over the internet. 3. The method of claim 1, further comprising: machining the first side of the part with the CNC machine using the identified and located material removal steps;applying support material to the first side of the part;machining the second side of the part with the CNC machine using the identified and located material removal steps; andremoving the support material from the part. 4. The method of claim 3, wherein the support material is applied as a fluid, and further comprising solidifying the support material prior to machining the second side of the part. 5. The method of claim 3, wherein the machining the first side of the part and the machining the second side of the part together result in total profile machining of the part. 6. The method of claim 3, wherein the machining the first side of the part and the machining the second side of the part together result in total profile machining of the part. 7. The method of claim 3, further comprising: machining a registration recess into the block of material with the CNC machine; andusing the registration recess to reoriented the part relative to the CNC machine. 8. The method of claim 3, wherein the support material is applied as a liquid, and further comprising solidifying the support material prior to machining the second side of the part. 9. The method of claim 3, further comprising providing the customer with at least one menu of customer-selectable values for a cost-affecting parameter of manufacture, wherein the menu is provided over the internet and the generated quotation is transmitted over the internet. 10. The method of claim 3, wherein the discrete portions of the part surface profile are automatically identified and located with a computer. 11. The method of claim 3, wherein the generating a quotation comprises evaluating a cost of a volume of support material used. 12. The method of claim 1, wherein the discrete portions of the part surface profile are automatically identified and located with a computer. 13. The method of claim 1, further comprising processing the received CAD file to assess whether the part surface profile passes an acceptability criterion, wherein the acceptability criterion is a single axis acceptability criterion corresponding to whether the part can be machined in a three axis CNC mill with only two opposing orientations of the block of material, with the CNC mill oriented in the z-direction removing material over a full x-y extent of an A-side and a B-side of the part. 14. The method of claim 1, further comprising processing the received CAD file to assess whether the part surface profile passes an acceptability criterion, wherein the acceptability criterion is a determination of whether the part has a geometry which can be formed through machining with a standard set of CNC machining tools, including whether any groove in the part has a tighter radius of curvature than smallest endmills and drill bits in the standard set of CNC machining tools and whether all grooves in the part have an aspect ratio which permits at least one of the standard CNC machining tools to reach a full depth of the groove. 15. The method of claim 1, further comprising processing the received CAD file to assess whether the part surface profile passes an acceptability criterion, wherein the acceptability criterion is a determination of whether all interior corners of the part have a sufficient radius of curvature to permit machining by one tool of a standard set of CNC machining tools. 16. The method of claim 1, further comprising processing the received CAD file to assess whether the part surface profile passes an acceptability criterion, wherein the acceptability criterion is a determination of whether the part can be machined out of a block of a selected material, including a determination of whether all ribs are sufficiently strong to withstand machining. 17. The method of claim 1, wherein the generating a quotation comprises evaluating a cost of machining a registration recess. 18. The method of claim 1, wherein the generating a quotation comprises evaluating a cost of a volume of the block of material. 19. A system for automated, custom manufacture for a part, the system comprising: A computer configured with an internet address to receive a CAD file from a customer for the part to be made, the CAD file defining a part surface profile;a memory storing a collection of information of material removal steps indicating surface profiles formed by the material removal steps to transform a block of material into a custom part; andone or more processors coupled to the computer and the memory, said one or more processors collectively programmed for:identifying and locating discrete portions of the part surface profile of the received CAD file to transform the block of material into the part, each discrete portion corresponding to at least one surface profile of one material removal step from within the collection of stored information; generating a quotation based upon the identified and located material removal steps; andtransmitting the generated quotation to the customer over the internet. 20. The system of claim 19, wherein the identified discrete portions of the part surface profile include at least a first discrete portion accessed from a first side of the part by a CNC machine and a second discrete portion accessed from a second side of the part by the CNC machine after the part has been reoriented relative to the CNC machine. 21. The system of claim 19, wherein all the identified discrete portions of the part surface profile together result in total profile machining of the part.
