1) Outer diameter undersized at one region.|2) ovality formation during the machining operation.|3) Eccentricity between the machine spindle and the revolving center is shifted due to historical accidents and the deviation in the eccentricity was left non-rectified,  because of which whenever the parts are machined with center support the consistency in machining was not achieved. Due to this issue the supervisor carried out trial in other two machines in the same cell in order to support the production for urgent requirement as the part proved machine was utilized for other priority job. The remaining parts got rejected during the trial process.|4) All the machines in the cell were having the same eccentricity issue.
