THE COMPUTERIZED BALANCING OF THE SPINDLE OF ESPECIALLY EXACT MACHINE TOOL UP TO LEVEL OF NANOMETR
Abstract
In this work the methods of the computerized balancing allowing considerably to reduce its duration by use of new approaches to traditional methods of trial start-up, and also a method of active influence on the fluctuations caused imbalance are considered.

EXPERIMENTAL RESEARCH OF STRESS OF GRAINS AND INTER-GRAIN BOUNDS IN A MODEL OF HETEROGENEOUS STRUCTURE MATERIALS
Abstract
In this research physical modeling is applied to investigate stress condition of carbide cutting tools as heterogeneous structure using method of photo elasticity. The photogram pattern interpreted and reveals the overall stress distribution in elasto-plastic bounds of rigid grains of the material.

EXPERIENCE OF OPTICAL-POLARIZATION MODELLING OF THE STRUCTURALLY-NON-HOMOGENOUS MATERIAL AREA
Abstract
The intense-deformed condition of grains and layers of non-homogenous materials are studying on optical-polarization models. The fields of pressure of cutting are modelling in the turning zone of non-homogenous materials adjoining to a forward side of a cutting edge.

INFLUENCE LOWAND HIGH TEMPERATURE EGR TO WORKING PROCESS ICE
Abstract
Influence of temperature exhaust gases recirculation (EGR) on parameters of working process in piston engines is considered. EGR it is important not only as one of methods of reduction toxicity of exhaust gases to ICE, but also a way of management of working process of engines with homogeneous charge compression ignition.

THE ANALYSIS OF THE CYCLE PISTON ICE AT POLYTROPIC PROCESS OF COMPRESSION-EXPANSION
Abstract
The analysis of a cycle of the piston engine based on a thermodynamic cycle with the mixed supply of heat in which compression and expansion are considered as polytropic processes with constants to parameters n 1 and n 2 is resulted, accordingly, that their influence on the basic parameters of a cycle allows to reveal.
