Analyse Phase

Analyse Phase

The next step in the DMAIC process is Analyse; I began this by finding out the scope of the machines we use in polish. We have a system which allows us to monitor the running time of our machines and also our downtime. See below



This shows that we only utilize 54% of our machines scope so achieving a higher output machine wise is possible now we need to look at how we can better manage the time for the operators so they can get achieve a higher output without increasing the ergonomic strain



The highlighted areas on this map are the areas we intend to make changes, firstly we noticed that we are repeating a step in grind and polish, in the grind jobstep we dry belt the part with a 220 belt and similarly we dry belt the parts in polish prep with a A65 belt.

In relation to the seven wastes this appears to be over processing of the part. 

Another change being brought in at NDT is also the implementation of a 8 part basket instead of a 4 part basket, this is beneficial as it will decrease the time it takes to run a batch down an automated line and free up the NDT operator to help the grind operator achieve a higher output also, this is vital as we cannot polish more units than we can grind as this will cause ‘’work in progress’’ (wip) shortages.

All this will be trialed and measured the Improve Phase.
