Abstract
he production of high-quality repaired engines is possible only with the right selection of technological equipment. The issues of the processing quality on honing machines rank first in the repair production, since the reliability of engines depends on the processing quality of cylinder liners. It is revealed that for a clear understanding of the feasibility of using old and choosing new technological equipment, it is necessary to evaluate it from the standpoint of an integral quality indicator. As a basic model for assessing the quality of technological equipment, use is made of the cost method. According to it, the cost index of quality as the value inverse to the integral indicator of product quality is formed for evaluating machines. It is determined by the value of the unit cost of processing one part calculated in cost form by groups of resource intensity indicators multiplied by the corresponding resource prices. Each cost group is the product of the resource price by its specific consumption in physical terms, resulting in a cost index of quality. For honing machines used for processing cylinder liners, a relationship was determined to analyze the cost index of quality. This index includes four basic elements – the indicators of material intensity, labor intensity, energy intensity of machinery and the material intensity of the inputs used in the technological process. The evaluation of the quality of machines has revealed that purchasing new equipment is economically feasible as technical and economic level of new machines exceeds the base level due to increased productivity, reduced energy consumption and unit cost. It is most advisable to use the ROBBI SET150-L machine (Italy) from among the new ones, since its integral quality indicator is significantly higher than its analogues. From among the old ones, NAGEL VS8-50 (Germany) should be recommended, while domestic machines should be replaced due to their low efficiency.
