Abstract

This study proposes to establish an optimal standard time for surface finishing of metal workpieces using the powder metallurgy process by a vibrating polisher with ceramic abrasive materials. This addresses the problem of the lack of clear time standards for the deburring and surface finishing steps, where employees typically set times based on experience and feedback from previous workers, averaging 60 minutes per cycle. This results in higher production costs and unnecessary energy waste. The experiment showed that the standard polishing time could be reduced from 60 minutes to just 50 minutes, or approximately 16.67%, while the resulting surface quality, free of sharp burrs and smooth, passed the customer's standards requirements.
