Abstract

Tegra Medical, based out of Hernando, MS, is a contract manufacturer of a wide variety of medical equipment. Currently, they are under a contract to manufacture a set amount of femur rods using their Swiss machines. In their current manufacturing process of these femur rods, a machine operator is needed to manually remove the femur rod from the Swiss machine when it is completed. This process requires the machine operator to pause the Swiss machine, open the front hood of the machine, remove the part, and then restart the machine to continue the manufacturing process. Because their current manufacturing process involves unnecessary steps that add time to the process, Tegra Medical has tasked our team to automate the ejection of the femur rods upon completion. Our team arrived at a final design of a bracket mounted air nozzle that will be installed in location 29 in Tegra Medical’s Swiss machines. Once the manufacturing cycle of the femur rod is completed, the secondary spindle of the Swiss machine will move to location 29, the femur rod will be pushed into the spindle by the air nozzle, and the femur rod will be ejected out of the back of the machine with 80 psi of air pressure. Our team’s design will reduce the femur rod production time by 60 seconds with an increase in units per hour of 32%.
