Wire Insulation Quality Control

For my Capstone Project with Encore Wire Corp, I designed and prototyped this semi-automated machine in cooperation with a team of five other engineering students. The  wire insulation measurement apparatus involves a mechanical thickness measuring solution using four needle penetrometers (linear actuators with linear variable differential transformer attachments) and a load cell for mass measurements. A 12-inch sample is inserted into the apparatus and thickness measurements are taken at 2” intervals along the length of the wire before it is scored and massed. The apparatus GUI then provides the operator with the thickness, alignment, and mass measurements to be included in quality control forms. The wire insulation measurement apparatus consists of a penetrometer plate consisting of four needle penetrometer units, two roller system units, a cutting mechanism, and a load cell basket encased in an 8020-Aluminum frame and polycarbonate external structure. The apparatu...
