MACHINE-TOOL AND CUTTING TOOLS PRODUCTION

Ivanov D. V., Ivanov V. S. — Formation of the structure — assembly decisions for turn-milling machines

From the analysis is determined that the cardinal problem decision of the blade machining efficiency increasing is the machine tools creature from the methods of forming multiple blade forming methods.
With regard to the processing of products such as bodies of rotation such a way is turn-milling in which the detail circumferential speed many times exceeds the speed of the circular feed speed of the instrument. Turn-milling, combining advantages multiblade cutting and tangentuial turning, allows intensifying cutting parameters and improving its performance compared to the turning from 1,5 to 2 times. The most rational is the structure and layout formation of the turn-mill machine on the basis of lathe or milling machine through the use of the principle of modular construction.
The proposed vectorial formalization of the relative position detail and tool with respect to the cutting area is universal to different processing circuits and is the basis for modeling the formation processes, analysis tasks decision and parametric synthesis.
The stages of the machine tool layout formation are adduced. Structure formalization principles, reflecting the quantitative and qualitative composition, the method of connection on and coordinate belonging its units are stated.
The layouts of the turn-mill machine tools pilot samples are represented.
Key words: machine tool, structure, layout, turn-milling, modernization

MACHINE-ASSEMBLING PRODUCTION

Bulygin I. A., Strogova O. V., Makarov A. F. — Effect of joint assembly with high strength thin-walled bush on the stress concentration in the bulkhead

The calculating model is adduced and stress-strain state from an external load in the plate with an eccentrically located hole in which is set a thin-walled high-strength bush with clearence fit or with interference fit is determined by finite element method.
Reasonability of the bush placing in the joint assembly hole with radial interference is determined on the example with the specific value of the design-technological parameters. At the transmission both compressive and tensile loading stress concentration decreases and improving the working conditions of such assemble are improved.
Key words: joint assembly; interference fit; bush; bulkhead; loading; circumferential, radial and equivalent stresses
