description: In the course of this work, test batches of samples of castings of crankshafts of the UAZ LLC enterprise were analyzed, and the main defects in these castings were identified. Based on the data on the analysis of defects in crankshaft castings, UAZ LLC developed and implemented measures to eliminate them and improve the quality of crankshaft castings produced. An analysis was also made of a test batch of crankshaft castings after the implemented improvements, and the economic effect was calculated. When calculating the economic effect, some assumptions were made: - The initial cost of casting the crankshaft was taken as close as possible to the real cost, since the real cost is a trade secret; - The cost of scrap and other charge materials was not taken into account, since they are reviewed once a quarter, and their price is regulated in accordance with the calculations between UAZ LLC and suppliers of these materials. Based on the data obtained, conclusions were drawn about the success of the implemented technological measures, and a new indicator of the yield of suitable crankshaft castings was also obtained, which increased by about 2.5 times. Also, the economic effect was 20.4% compared to production without the introduction of improvements. The increase in the cost of one casting of the crankshaft was 9.5% or 274.7 rubles. The yield of suitable castings meets the requirements that were presented before the improvements introduced, and the increase in price is within the limits of the conditions presented. Thus, it can be concluded that the implemented measures to improve the castings of crankshafts in the conditions of the UAZ LLC enterprise can be considered successful.
