Well, for some time we’ve taken to building new Bore Gage for a customer. In an odd twist, I had very little to do with the mechanical design but was primarily focused on the electronics and software.
Basically what this device does is measure the bore of a hydraulic cylinder in a comparative way all the way down the bore. It uses a Mitutoyo encoder for the diametrical size and a US digital rotary encoder on the wheel to keep track of the distance down the bore. As the device measures, it keeps track of the position and the measurements therein and creates zones where an average, maximum, minimum and sample size is kept. It is then plotted out along the distance.
Anyways, I had some fun doing this project and I am looking forward to doing more.
