Abstract: Southco, Inc. is a manufacturer of access hardware of many types. One line of hardware is completely dedicated to captive fasteners. These captive fasteners utilize a standard screw with a spring and round standoff over the shaft to create a sprung fastener which can be fastened onto panels. When these standoffs are milled from raw bar stock on either Davenport or Wickman machines, there are occurrences of small chips of aluminum or steel that become lodged in the inner and outer diameter. During assembly, these chips can cause frequent jamming. The jamming of the assembly machines causes significant down time and the standoffs removed become waste because they can not be recycled. The removal of these chips from the process has been discussed at Southco, but no real solution has come about. It is our objective to find a method to remove the chips before they enter the assembly process. There are several alternatives being considered. These alternatives range from machines that utilize air for either suction or push, oil, and other alternatives that would utilize a small pin to push out the chips. Out of these alternatives the design team will choose the most reliable and cost efficient method. The final product will be a machine that separates and possibly sorts these standoffs and chips, or a component add-on to the existing assembly machine.
