Quality Assurance Check Gages

After developing and printing the gage model based on the part CAD data, the gages were dimensionally verified using a CMM to ensure their capability to check the intended part attributes. The gages shown near the top in the image above were designed to check the form of sheet metal parts. Due to the complexity of measuring bendy sheet metal, the gages can be used to quickly tell an inspector if the part is good or not. The parts shown in the bottom of the image above were used to check the form of various parts made that were milled or waterjet. Copies of the gages were also produced and given to the production team to catch parts on the manufacturing floor and to be used as a diagnostic tool.

(I often worked with the QA team to develop tools)

My Role: Project owner, developed, manufactured, and verified all of the gages pictured above as well as the copies used on the production floor.

The tool pictured above was developed to measure the dimensional variance between two circular concentric rails. The two back corners rest against one rail, ensuring perpendicularity, and the dial indicator tip rests on the other rail. The thickness of the tool was designed to ensure that the dial indicator was in the correct position when resting on the part. The tool could then slide between the two concentric rails and verify a variance dimension all the way around the rails.

My Role: Project owner, I was tasked with designing a tool that measures the variance without the need for a CMM. I designed, modeled, and manufactured the tool.
