【 摘 要 】

The work represents the approaches for designing the quality system for gas turbines engines parts additive manufacturing. For gas turbines engines applications, the quality parameters obtained by the selective laser melting are insufficient and require the subsequent surface treatment. To reduce the cost of additional manufacturing and improve the quality parameters, it is necessary to predict the surface structure that could be formed by selecting process parameters. The paper deals with each element of the selective laser melting technological process which effects on the manufactured part quality and suggests appropriate measures to achieve and maintain a high level of quality.
