Communicating mold/part manufacturability issues
A computer program analyzes a CAD file provided by a customer of a custom part to be injection molded. Feedback from the analysis is provided to the customer through a rendering of the part. Rather than merely communicating using color as applied to the rendering file and separate text, the invention applies one or more symbols as “decals” to the rendering of the part provided to the customer. In one preferred embodiment, the symbols are chevrons or arrows which indicate the direction of additional draft needed on particular faces for the part to be sufficiently manufacturable. The symbols are sized appropriately for the size of the face to which they are applied, and are oriented to match the orientation of the face. The symbols may also indicate other information, such as the magnitude of draft needed, magnitude of thickness required, the surface finish to be applied at that location, or time or location based properties of the injection molding process.
1. A process of communicating with a customer with regard to changes required to be made to a customer's part design for manufacturability by a manufacturing process, comprising:
analyzing the customer's CAD file for the custom part to be manufactured;
providing a part rendering to the customer based upon the analysis, the provided part rendering including one or more symbols placed on a face of the part rendering indicating changes to part geometry from the part geometry of the customer's CAD file to assist in manufacturability of the part and/or mold.
2. The process of claim 1 , wherein the symbols indicate direction.
3. The process of claim 2 , wherein the symbols indicate direction of additional draft needed on that face.
4. The process of claim 1 , wherein the symbols indicate magnitude.
5. The process of claim 4 , wherein the symbols indicate the magnitude of additional draft needed on that face.
6. The process of claim 1 , wherein the part comprises faces, and wherein the symbols are applied to one or more but less than all of the faces of the part.
7. The process of claim 1 , wherein the manufacturing process is injection molding.
8. The process of claim 7 , wherein the part comprises faces which are separately defined based upon parting lines between A side, B side and any side actions of the mold, and wherein the symbols are applied to one or more faces of the part.
9. The process of claim 1 , wherein the CAD file is analyzed by a computer and the part rendering is provided to the customer by a computer.
10. The process of claim 9 , wherein the size of a symbol is computer selected to correspond with the size of a face to which the symbol is applied in the rendering provided to the customer.
11. The process of claim 1 , wherein the part rendering provided to the customer is a three-dimensional rendering which is manipulatable by the customer, with the symbols placed on a face of the part being manipulatable with the three-dimensional rendering of the part.
12. The method of claim 1 , further comprising:
manufacturing the changed part by the manufacturing process; and
providing the manufactured part to the customer.
13. The method of claim 1 , wherein the analyzing is performed with a computer processor.
14. The method of claim 1 , wherein the customer can view the part rendering.
15. A process of communicating with a customer with regard to changes required to be made to a customer's part design for manufacturability with a manufacturing process, comprising:
analyzing a customer's CAD file of a custom part to be manufactured, the analysis identifying portions of faces which require changes from the customer's CAD file for manufacturability reasons;
providing a part rendering to the customer based upon the analysis, the provided part rendering including identification of entire faces which need to be changed from the customer's CAD file even though just portions of the face failed the manufacturability analysis.
16. The process of claim 15 , wherein the identification includes symbols applied to the entire faces which need to be changed.
17. The process of claim 16 , wherein the symbols indicate direction.
18. A process of communicating with a customer with regard to injection molding of a customer's part design, comprising:
analyzing a customer's CAD file for a custom part to be injection molded;
providing a part rendering to the customer based upon the analysis, the provided part rendering including a plurality of symbols placed on a face of the part, with the symbols indicating direction at particular locations on the part.
19. The process of claim 18 , wherein the symbols indicate magnitude at particular locations on the part.
20. The process of claim 19 , wherein the magnitude indicated is the magnitude of additional draft needed for manufacturability.
21. The process of claim 18 , wherein the direction indicated is the direction of additional draft needed for manufacturability.
22. A computer program for assisting customers with designing injection molded parts, the computer program comprising:
an input dedicated for receiving a customer's CAD file, the CAD file defining a shape of a part to be molded;
computer code recorded on a computer-readable medium for analyzing the customer's CAD file for injection molding; and
an output providing a CAD rendering of the part, the CAD rendering including a plurality of symbols placed on one or more faces of the part, with each symbol indicating a direction associated with the injection mold process at a particular location on the part.
