Abstract: The new idea of products’ quality insurance as well the control effectiveness lay down the necessity of a strong interaction and integration among different branches of engineering. The structure effectiveness for processing and control is worldwide a top concern.
The dimensional inspection automatisation is one of the main requirements for the technological improvements of the manufacturing systems in all industrial fields. The bearing production has to undertake a continuous quality improvement due to its major economic involvement; the consequence consists in high performances in the quality ensuring.
As an integrated field, the control automatic devices include the classic mechanic engineering, electronics and computer field in designing, control and evaluation for these systems.
The bearing industry achieved in our country special results in the inspection automatic devices field. The currently used automatic drive systems are manufactured for concrete service and are equipped with elementary components.
Through the modulating of the component subassemblies and the using of microelectronic systems with the worldwide highest performances for control and drive and based on a detailed analysis of the automate control systems, this paper emphasizes some important items with reference to the quality assurance in Bearing Industry.
In this paper are being approached a few aspects concerning the dynamic behaviour of automatic systems for bearings inspection with the aim of achieving the best structures from the efficiency and quality assurance point of view.
The analysis of the results obtained during the optimisation process lead to the elaboration of new possibilities of assuring the structures of optimum automatisation from the efficiency, quality and energy consumption point of view, for different types of bearings.
