No. 2, The following information was obtained from a Roller shop of Lattim Steel Company which works for three shifts of 8 hours each. They monitor the OEE every day. The time allotted for tea breaks, lunch, morning meetings, etc. accounts for about 2.66 hours. It was found that a mechanical coupling in one of the rollers has broken down and about 1.66 hours was spent on repairing it. Similarly, two different sizes of steel plates have to be rolled, and it took about 1.46 hours for doing the changeover on the rollers. It was also found in some of the rolling machines, the operator was not available, but the machine was running without any feed of the steel stock. This accounted for about 1 hour. Since the steel has to be in a hot condition to obtain a particular hardness before rolling, the furnace temperature has to be maintained at a prescribed temperature. It was found that the operator spends time on adjusting the furnace temperature, and it consumed about 1.83 hours. The rolling department has been designed to roll about 12.5 rolls per hour. On that day, about 100 rolls were produced. About two rolls have to be scrapped because it did not meet the required thickness, while another five rolls were wasted because of poor hardness after setting up the machine. One of the rolls had excess thickness, and it was rolled again to get the required thickness. Based on these details, a. Identify the different losses for the roller shop b. Calculate the Overall Equipment Effectiveness (OEE) for the press shop and comment about their performance. (3 + 7 = 10M) bottling machines that are used.
