Systems, methods, and tools for proofing computer-aided design (CAD) objects (e.g., CAD drawings or models). The objects are implemented with CAD software and represent an apparatus. An exemplary method includes receiving a CAD object representing the apparatus, determining criteria for proofing the CAD object, determining rules, extracting items of interest from the CAD object, comparing the extracted items with the rules, and tagging the extracted items based on the comparisons. An exemplary criterion for proofing the CAD object is the thickness (e.g., a sheet metal thickness) for the apparatus to be manufactured in.

摘要:
A reusable torque limiting device producing tactile feedback for a desired preset bolt tensile load comprises a body, provided with an internal bore threaded therethrough so as to be received over a threaded bolt or similar fastening element. One face of the body is provided with a recessed area therein and an angled counter-bore adjacent and concentric with the center thereof. One or more angular, beveled or concave members are disposed within a recess in the body with the concave portion suitably oriented relative to the recess. The work piece engaging face of the body is, or may be provided with, a roughened surface for example radial slots, notches, teeth or grooves so as to gall or abraid the confronting face of the work piece as the device achieves the predetermined bolt tensile load that is desired by allowing the torque rate increase to be easily sensed at which time the operator should stop turning the nut. (This device makes use of the operator tactile senses to achieve accurate tensile load in the bolts.) Additionally, an indication that the annular beveled members are located correctly within the recess in the threaded body of the device is provided by the slots or grooves.

摘要:
A hydraulic pressure damper element is manufactured by shaping a stainless steel tube; flattened each end of the tube; and sealing a gas within the tube. Wire retaining devices may also be attached to the ends of the damper in order to support the device within a fuel rail tube in a fuel system.
摘要:
A plastic tolerance proofing tool adapted to be implemented with a computer system. The computer system includes a processor and a memory storing a CAD object of an apparatus to be manufactured with a material. The tool includes a criteria selector operable to prompt for and receive a type of plastic material for the apparatus to be manufactured in and an extractor operable to determine a nominal dimension and a related tolerance from the CAD object. The tool further includes a comparator operable to compare the tolerance with a first threshold and a second threshold, and a tagging module operable to tag the CAD object based on the comparisons.
