DESIGN AND FABRICATION OF MODULAR FIXTURE FOR CMM INSPECTION

Abstract

This paper is on design and fabrication of modular fixture setup relative to inspection on co-ordinate Measuring Machine proposed and planned to increase the utilization of Co-ordinate Measuring Machine with respect to inspection activity by reducing setup time. The modular fixture design will hold component of different configuration, size and shape without much efforts to locate, align and clamp the components on the fixture. The modular fixture will ensure that even though the component is of different configuration will have one time design and setup configuration which will be standardized by assembly of fixture and then on fixture setup time will be less than a minute on the machine that to only if fixture is disturbed / removed from the Coordinate Measuring Machine table. Modular fixture will reduce setup time, hence increase opportunity to utilize the machine for useful value adding inspection purpose rather than setup activity which is noted to be non value adding activity. Along with design of modular fixture standardized method of component setup strategy is provided as work instructions to ensure components are mounted same way each time and every time whenever it is in use irrespective of time and resource.
