Title of the project: SMED (Single Minute Exchange of Die), continuous improvement activity for crank changeover process.
Brief Description of the project: Use SMED techniques to reduce changeover time through system for crank machining to throughput simulation approved levels.
Activities to be performed by trainee: * Update crank changeover board to reflect the current. * Create and manage tracking sheet of changeover issues and countermeasures. * Measure changeover times by operation. * Get changeover within

SETUP CHANGE / CHANGEOVER
Setup change/ Changeover is preparation, execution of activities in work station which includes hardware changes, sometimes software changes e.g.: locator centres, chuck jaws, steady program calling etc. to produce good to good parts. Change over time is defined as the time difference of the last product produced and the next new product produced with the right quality and at the right speed. The production capacity of a plant is determined by the changeover time. Unless the changeover time is reduced to the bottleneck the production can’t meet the target
Production sites with long setup times are characterised by * Low flexibility of the component * Large batch sizes * High levels of stock
If we decrease the setup change time then we could use the extra capacity either to increase productivity or to decrease the batch sizes. There are many benefits likereduction in lead time and therefore increased, improved and faster delivery, higher productivity and therefore satisfying customer needs faster, Reduction in working capital, less disturbances etc.

SINGLE MINUITE EXCHANGE OF DIE (SMED) The process of changing die is called Single Minute Die Exchange (SMED). Single-Minute Exchange of Die (SMED) is one of the many lean production methods for reducing waste in a manufacturing process. It provides a rapid and efficient way of converting a manufacturing
