Germashev A. Increasing of end milling quality of thin walled elements of the details by using special technological materials

Object of study - machining of thin-walled elements of the detail with using special technological materials (TM). The aim of research is to identify the regularities of mode characteristics changing of thin-walled detail by using TM to improve quality of surface finish. Research methods - experimental. The experimental data processing was carried out by the methodology of evaluation of vibrations during thin-walled details milling by statistical and correlation analysis. Theoretical and practical results: it was developed a perspective technology of using special technological materials in manufactory, it was introduced special design of the tool for milling details, which are surrounded by TM, it was presented device for comparison and selection of TM and also methods of evaluation of the vibrational motion of thin-walled element during milling was proposed. Scientific novelty: for the first time was developed a set of criteria of evaluation the conditions of the vibrational of thin-walled element during milling, for the first time was found that the vibration stability and efficiency removal rate depend on spindle speed. For the first time it was shown that contact between processing detail and TM is not stable. Further develop obtained the idea of the possibility of improving the technology of efficient use of special TM. The degree of realization: the recommendations of using developed technology is transferred to JSC "Motor Sich"and introduced in the educational process of Machine building technology Department of ZNTU. Scope of using results of the work - machine building industry, aerospace industry, in research institutes and educational process.
