  • Patent number: 10556309
    Abstract: Methods involving adding a removable fixating material to a partially manufactured workpiece to stabilize a plurality of partially formed objects therein for subsequent manufacturing. In one example, valleys are formed in a workpiece between adjacent partially formed objects so that interconnecting portions remain to interconnect the partially formed objects. Then, the removable fixating material is installed in the valleys, and once the removable fixating material has hardened, the workpiece is further processed to at least remove the interconnecting portions. In some embodiments, a mold is used to install the removable fixating material into the workpiece. In some embodiments, a prefabricated temporary frame is used for installing the removable fixating material into the workpiece. In some embodiments, a temporary frame is formed from the workpiece along with the plurality of objects during manufacturing.

  • Patent number: 10545481
    Abstract: Methods and software for generating machine-control instructions for controlling subtractive manufacturing equipment to form a plurality of objects from a single workpiece. In some embodiments, the machine-control instructions are for milling equipment that mills the objects from a single body of material by milling material from obverse and reverse sides of the body of material. Milling from the obverse side forms valleys in the obverse side and leaves interconnecting portions that connect together the plurality of objects. A removable fixating material is added to the valleys for holding the objects firmly in place relative to one another for milling from the reverse side. After the removable fixating material has hardened, milling from the reverse side removes the interconnecting portions. Milling operations from the obverse and reverse sides can include operations in addition to the forming of the valleys and removing of the interconnecting portions.

  • Patent number: 9927803
    Abstract: A process for creating custom fixtures for parts that are to be CNC lathe machined is fully automatic and requires no human interaction. The customer's CAD file is computer analyzed to determine whether the part's dimensions fit within an available CNC lathe turning center for forming out of a cylindrical stock bar. The longitudinal axis is identified, and a set of tool paths is developed for cutting the part from two respective directions. A corresponding tool path is developed for CNC lathe cutting a bushing, preferably from the same bar stock, which generally represents the negative space around circular cross-sections of the part, in monotonically increasing diameters from the first end of the part. The bushing is then used to hold the part in the chuck during machining the second end of the part from the opposite direction.

  • Patent number: 8745517
    Abstract: Any issues associated with manufacture of a part are identified and highlighted on a part rendering. A software method and system then uses a visual change cue on the part rendering for communicating the manufacturability issues to the customer. The preferred visual change cue is a throbbing of the highlighting of the manufacturability issue, with the throbbing occurring in both color intensity and size. The part rendering depicts the part translucently, so throbbing manufacturability issues can be readily identified even if obscured behind a more-forward face of the part.

  • 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: 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.
