EVALUATION OF MANUFACTURING OPERATIONS RELIABILITY ON TECHNOLOGICAL PATH OF PROCESSING TOOLS
Abstract
Processes and equipment are classified based on mutual interactions between elements of a technological system. Reliability of each type of the technological system and operated process is different due to varying complexity of the performed operations. The main properties-determining feature of the process is the interaction of the constituent element of the technological process, mainly instrument and machining object. Based on this, technological processes in the interaction zone are divided into four groups: pointed, linear, surface and volumetric. Groups of the technological processes and determination of the reliability of their operations during goods formation is described. Colligation of the technological path with component failure rate is shown. Calculations of the technological path for each group of processes are presented. Intensities and failure rates for the all groups of processes are calculated. Based on the calculations of the object technological path, evaluation of reliability of performed operations for each group of the interactions was obtained. Obtained regularity of the component failure rate during decrease of the technological path allows quantitative comparison of the manufacturing operations reliability during its designing.
