  • Patent number: 8295971
    Abstract: A computer program, system and method receives a customer's CAD file of a custom part to be formed. Depending upon customer responses to several basic queries, the CAD file is analyzed to identify acceptable holes for tapping. For each identified hole, an appropriate and available thread size is automatically selected, even if the cylindrical recess differs in size from the characteristic size of the threaded hole. The customer is then automatically advised 10 of the results of the tapping analysis, preferably as part of a quotation for part manufacture that identifies the number of threaded holes in the part and preferably identifies the changes to the tapped holes and the specific thread form being quoted for the hole.

  • Patent number: 8239284
    Abstract: 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.

  • Patent number: 8140401
    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.

  • Patent number: 7957830
    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.

  • Patent number: 7836573
    Abstract: A method and apparatus are provided for total profile machining of a part, such as from a block of thermoplastic polymer. A first side of the part is machined together with an encircling recess. A registration/potting fixture is placed into the encircling recess. The registration/potting fixture is used to evacuate air from the machined side of the part and to pressure pack degassed fluid potting compound against the machined side of the part. The registration/potting fixture is cooled such as with a coolant to solidify the potting material. Then the registration/potting fixture is used to fixture the block in a new orientation for CNC machining another side of the part. Upon removal of the potting material from the part, the total profile machined part is freed for shipment to the customer.

  • Patent number: 7630783
    Abstract: 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.

  • Patent number: 7590466
    Abstract: Automated, custom mold manufacture for a part begins by creating and storing a collection of information of standard tool geometries and surface profiles machinable by each of the standard tool geometries. 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 manufacturability. 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 an independent of the shape of the part.
