Evaluation of the influence of manufacturing errors on the quality of sealing joints installation

Abstract

In production process, the leading role belongs to installation as a final stage, where the main quality indicators, reliability and durability of the produced objects are formed. However, the analysis of machine building development trends in the recent years shows that even in such highly automated industries as automobile and tractor construction, in view of labor intensity, installation takes second place after machining. In the general structure of labor intensity of machine manufacture, it amounts to 35-60% of the total labor intensity and exceeds labor costs at all stages of production [1]. In machine building, about 25-30% of operations are mechanized, and no more than 5-6% of operations are automated [1]. Therefore, installation works are inefficient and expensive, resulting in the significant increase of the finished product cost and decrease of its quality.
