In addition to providing a thorough definition of jigs and fixtures, this study also outlined the multiple advantages of use of jigs and fixtures and its impact on production of PCB layouts. These benefits include increased productivity , reduced cost of machining and various other costs involved , interchangeability and high accuracy of parts, reduced need for inspection and quality control expenses, reduction of accident due to improved safety, automation of machine tool to a significant extent, and ease of machining of complex shapes. Different industries need different types of fixtures depending on their use. Manual labour is used to put up the fixture for the component. For the longer cycle time that is needed to load and unload the material . In the presented work ,the designing of a press tool and its manufacuring is done where the output is a circular PCB and the press machine used is of mechanical type . |
