Kalafatova L. Technological Basis of Raise of Efficiency of Machining and Provision of the Required Quality of the Articles Made of Technical Glass and Cetalls

The object of the thesis is the technology of machining of articles made of technical glass and cetalls. The aim of investigations is to develop technology basics of articles machining through giving backgrounds of rational machining conditions (schemes and grinding regimes, tools characteristics, technological media features, machining sequence). The methods of the theory of machine-building technology, fracture failure and defects forming, those of mathematical and computer modeling, fluoroscopic flaw detection, and the defectness automated evaluation were applied to the investigation process. The mathematical model of defectness forming under the grinding process, the machined surface defectness layer development made by computer and mathematical modeling of the cutting zone deformation mode, the possibility of influence of technological media on quality parameters forming, method of calculation of rational in-process stocks with taking into account the defective layer transformation and technological heredity were first to have been developed and investigated. The output implications of development of technological processes of articles machining with the minimal cost of the latter were founded. The recommendations as to the articles efficient machining were developed and set into manufacturing. The sphere of Application: enterprises dealing with glass materials machining.
