Carrier tape is used for packing SMD parts in electronic industry. The potholes for the parts are made by being punched in series using a punching machine. The interval distance and shape is crucial and should be within the specified dimensional limit. In this paper a visual inspection algorithm is proposed in order to measure the rectangular shape. The algorithm is based upon the edges in order to...
In some industrial fields such as optical part mold making or fabrication of the nano structure by ultra-precision machinery, an ultra-precision positioning system is widely used. In this paper, an experimental ultra-precision positioning system is designed and fabricated, consisted of an ultra-precision stage supported by flexure hinges, a piezoelectric actuator and an ultra-precision linear encoder...
