Engineering product quality control at all stages of product life

In the paper it is shown that at quality control of engineering products particular attention should be paid to engineering and technological measures which exert basic influence upon assurance and quality increase. Technical and technological measures are shown at all stages of product life: marketing; design; technological pre-production; manufacturing materials, blanks, parts and their assembly; operation; repair and utilization. It is emphasized that still at the preliminary stages it is necessary that a factor of competitive ability of a product designed should be defined. It is shown convincingly that engineering product quality is formed at the stage of design and ensured at the stage of manufacturing. The realization of measures shown in the paper allows ensuring high-quality competitive engineering product manufacturing at enterprises.
