Development of a Novel Jig Design to Reduce Fabrication Time of Metal Parts | Chapter 3 | Research and Developments in Engineering Research Vol. 4

 Machining is ultimate prevalent production operation in conditions of volume and payment.  Machining operations of complex parts need expected properly thought so that save occasion and improve the competitiveness of the parts. Often, jigs and fittings are overlooked in grinding processes, as an auxiliary tool, but these can help in optimizing a build process as a part of unending improvement. The means used for this study was   base an growing demand forecast of a complex part, called Winding pyramid, which implies a decline in the takt time from 4.6 to 2.6 notes per part. This research tries to establish highest in rank solution for the project, that was divided into four aspects: research, design, machining, and exercise.  The design phase was established the methodology of Design for Six Sigma methods (DFSS) for the fixture. The project's fault-finding outputs were harvested during the exercise phase.  The recently designed and created modular trick system is capable to deal with 12 parts per era, proving expected able to increase the number of parts build per day by 32%, with wonted savings of in addition to €6000 per year. This intensely reduces the lead times for new parts, that is crucial for a narrow-medium enterprise stay aggressive. The new jig design and lie allowed easy loading and unloading of parts.
