摘要:
A system and process for managing measurement data and generating production and engineering drawings from measurements obtained from a sample population parts to generates and parametrically update engineering and production drawings from measurement data of actual parts. The system and process provides efficient allocation of measurement resources to generate engineering drawings and models. The resources are allocated in a manner that eliminates and reduce time required for producing and generating usable engineering models and drawings.

A filler material is melted into a metallic substrate having a defect under conditions chosen to preclude cracking. In a preferred embodiment of the invention, a laser beam is operated at a relatively low power density and at a relatively large diameter for an extended length of time to produce a molten pool with a low aspect ratio.

A disclosed harness assembly includes a base including a mounting surface and an opening that receives a mount end of a harness clip. A lockable clip is moveable between open and closed positions to secure one or more supply conduits or wire harnesses. The opening of the base includes a securement feature that corresponds with the mount end to hold the harness in a desired orientation relative to the base, to provide a fixed topographical routing.

A containerless method of producing a crack free metallic article of near-net shape includes melting a filler material into a metallic substrate or seed under conditions chosen to preclude cracking. In a preferred embodiment of the invention, a laser beam is operated at a relatively low power density and at a relatively large beam diameter at the substrate surface for an extended length of time to produce a molten pool with a low aspect ratio. Near-net shape is achieved by applying the process in a closed-loop, multi-axis material deposition system.
摘要:
A method of evacuating uncured resin from internal passages of semi-hollow stereolithographically produced objects includes, subjecting the object to air flow for between about 0.5 hours and about 2 hours, at a temperature greater than about 75.degree. F.; externally cleaning the object with alcohol; submerging the object in a bath of alcohol, wherein the bath is internally agitated; removing the object from the bath and repeating the above steps to displace any residual resin, wherein total object exposure time to alcohol does not exceed three hours.
摘要:
A method of creating an article from investment casting includes forming a ceramic seed well, heating the ceramic seed well to form a hardened ceramic seed well, attaching a meltable pattern to the hardened ceramic seed well, coating the hardened ceramic seed well and the meltable pattern with hardenable ceramic material, heating the hardenable ceramic material to melt the meltable pattern, removing the meltable pattern from the hardenable ceramic material, firing the hardenable ceramic material to form a ceramic mold having a cavity, placing a seed within the hardened ceramic seed well, and pouring molten metal into the hardened ceramic seed well and the cavity. The cavity of the ceramic mold is in communication with the hardened ceramic seed well.
