Abstract

A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. 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, 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. 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.

Claims

1. A method of budget-driven, custom quotation for manufacture of a mold and/or manufacture of a part, the method comprising:

receiving customer part data comprising a CAD file for the part to be molded, the CAD file defining a part surface profile;

assessing cost-affecting parameters of mold manufacture and/or part manufacture determined by the part surface profile;

receiving a budgeted dollar amount for the part;

automatically generating a quotation for mold manufacture and/or part manufacture based in part upon the cost-affecting parameters determined by part surface profile and based in part upon the budgeted dollar amount, the quotation comprising proposed changes to the customer part data to enable the quotation to fall within the budgeted dollar amount; and

providing the automatically generated quotation including the proposed changes to the customer.

2. A method of interactive quotation for manufacture of a mold and/or manufacture of a part, the method comprising:

receiving customer part data comprising a CAD file for the part to be molded, the CAD file defining a part surface profile;

assessing cost-affecting parameters of mold manufacture and/or part manufacture determined by the part surface profile;

generating a quotation for mold manufacture and/or part manufacture based in part upon the cost-affecting parameters determined by part surface profile, the quotation including a price; and

providing the generated quotation to the customer on a computer screen, the generated quotation including at least one interactive parameter, wherein the customer can interactively change the at least one interactive parameter to result in real time modification of a different, non-price modification parameter of the quotation.

3. The method of interactive quotation of claim 2, wherein the at least one interactive parameter is selected from the group consisting of customer part data and price.

4. The method of interactive quotation of claim 3, wherein the at least one interactive parameter comprises price, and the modification parameter comprises part surface profile, such that the customer'"'"'s interactive changing of price results in a real time morphing of part surface profile of a rendering of the part on the computer screen.

5. The method of interactive quotation of claim 2, wherein the interactive changing of the interactive parameter is through an on-screen slide bar.

6. The method of interactive quotation of claim 2, wherein the generated quotation includes at least two interactive parameters, and wherein the customer can fix one of the interactive parameters as a constraint.

7. The method of claim 2, wherein the at least one interactive parameter comprises surface finish.

8. The method of interactive quotation of claim 2, wherein the generated quotation includes at least two modification parameters, and wherein the modification parameter modified as a result of a customer'"'"'s change of the interactive parameter is algorithmically selected.

9. The method of claim 8, wherein the algorithmic selection is based upon the most popular accepted modification parameters of prior quotations.

10. The method of claim 8, wherein the algorithmic selection is based upon the least significant change in price.

11. The method of claim 8, wherein the algorithmic selection is based upon the marginal revenue associated with the modification.

12. A method of custom quotation for manufacture of a mold and/or manufacture of a part, the method comprising:

receiving customer part data comprising a CAD file for the part, the CAD file defining a part surface profile;

assessing cost-affecting parameters of mold manufacture and/or part manufacture determined by the part surface profile, the assessment comprising alternative methods of machining;

automatically generating a quotation for mold manufacture and/or part manufacture based in part upon the cost-affecting parameters determined by part surface profile, the quotation comprising the alternative methods of machining.

13. The method of claim 12, wherein the quotation comprises a graphical rendering of the part showing the portions subject to alternative methods of machining as part of the quotation.

14. The method of claim 12, wherein the alternative methods of machining comprise use of different machining tools.

15. The method of claim 12, wherein the alternative methods of machining comprise electro-discharge machining (EDM).

16. A method of custom quotation for manufacture of an injection mold and/or manufacture of an injection molded part, the method comprising:

receiving customer part data comprising a CAD file for the part to be molded, the CAD file defining a part surface profile;

assessing the CAD file data to analyze a shot thereby generating a quality of part parameter;

generating a quotation for mold manufacture and/or part manufacture based in part upon the quality of part parameter, such that parts which are more difficult to produce in quality with injection molding are quoted differently than parts which are easier to produce in quality with injection molding.

17. The method of custom quotation of claim 16, wherein the assessing the quality of part parameter comprises calculating likelihood of completing injection mold fill with a selected material.
