ollect all the tools according to the part which is going to be worked in the particular machine and they pre- kit the right tools to place it near the machine before the machinist's starts the operation. The tool crib properly calibrates the tool and makes it easier for the machinist to use the right tool. This helps the machinist to gain confidence in the tools which he is going to use. The more the number of tools used the more is the setup time. With the help of the tool crib the right number of tools is used which helps to minimize the setup time thus saving considerable amount of time and energy.

The role of a machinist is also very important in this system. The machinist reconfirms the work piece placed by the production control by checking the overall ID and OD and the material type before starting the work. This confirmation reduces the variability in the system as in case if the machinist starts working without confirming the ID and OD he may end up in part oversize or under size eventually leading to a scrap.

The machinist also checks for the right standard CNC program to be loaded in the machine before the previous job has finished. The word standard program is used because there were cases in which the machinist tends to adjust the speed and feed rate at his comfort which changes the program parameters. Thus leading to a big variation in the run time of the product each time when a similar work is performed. This also varies from shift to shift as each operator has his own standard of performing the job. It should be noted that as the program changes the tools accordingly are changed, so the importance of standardized program is emphasized to the machinists.

Once the machinist has confirmed the part dimensions, material and the program the machinist initials in the board near to the machine confirming that the setup is completed, and there could be no chance for failure. This board system also helps to reduce pinpointing other departments when some scrap part occurs.

The next in the cycle is the coordinator, who checks the complete start up process. After the coordinator completes his task, the cycle is now passed on to the production control, and the same cycle is repeated. The role of the coordinator in this system is very critical as his job would be to implement the standardized programs in the shop floor, and he has to make sure there would be no complaints or flaws during machining. If the machine could stop running it could cost a lot of resources so the coordinator takes charge and completes the paper work making sure everything is perfect.

These activities are done before the previous part is machined. There by the machinist just needs to load the part, use the right tools to complete his work on time consistently. This system help reduce the set up time for machining any given part in this high variety low volume environment.
