Virtually all products that are finished require some pre-finishing procedure such as cleaning, stripping, or pickling. Without a properly cleaned surface, even the most expensive coating will fail to adhere or protect the workpiece. Depending on the process being performed, the degree of cleanliness will vary. Finishing operations such as phosphating, chromating, or electropolishing do not req...

This study investigates a Deburring process which is integrated with a robotics application. Conventional tumble deburring processes have been used for years in the surface finishing industries. The manual process is tedious, inconsistent and inaccurate. Automation in the finishing process has been proved very beneficial. Integration of robots in the process provides more flexible and convenien...
