Among of existing great quantity of different automatic designing systems of the cutting tool, any of them doesn't correspond to the system of the automated designing cutting tool conditions, all of them are practically reduced to systems providing computer graphics.
Information technology for determination of parameters at a design stage of manufacturing techniques of articles with ensured reliability and durability is created by methods of cold forging and a sheet-metal forming.
Conception of optimum control machining is first developed on a machine-tool with CNC on a priori information through system of the automated preparation of the programs depending on the conditions of cutting in the direction of shape-generating co-ordinate and time of machining. The presence of optimum depth of cutting is well-proven at multi-pass machining, that allowed to formalize the task of planning of trajectories on draft machining and task optimization of the cutting mode.
New approaches are developed to determination of chemical composition of alloys for making of the poured details from heat-resistant and wearproof alloys on the basis of iron. Smallalloying and modifying elements, their action, are certain on properties of alloys and optimum correlations for work of the poured details in extreme terms. The methods of determination of kinetics of oxidization of heat-resistant alloys are developed in different aggressive environments, them firmness against oxidization , heat-resistance, steady to growth and wearproof.
The monitoring system includes equipment, methods, and software. It was designed for the following purposes: Measurement of mechanical stress within the main pipeline, located in potentially dangerous areas. Transmission of measurement data into operator’s server. Graphical representation of the current stress distribution in a horizontal axis of a pipeline. Graphical representation of stress changes in the points of measurement over time.
One of the most informative human speech-creating organ for speech recognition problem is voice source that effects basic tone frequency of speech signal. According to researches, human hearing system uses basic tone frequency for speech recognition with high reliability, but it is sensitive to low-frequency noises – so appeared idea to use spectral characteristics of speech signal segments, where extremums of correlation function can be found, as additional features.
Estimations for the dynamical properties of tree-nitrides compounds (InN, GaN, AlN) were obtained, using semi-analytical expressions for momentum and energy mean free times in strong fields. Field-temperature dependences, occupation of the valleys, velocity-field charactistics in strong fields with different modifications of crystal lattice (cubic and hexagonal) were calculated. These results were compared with existent experimental data, calculated by other authors.
Design of thin-walled metal tubes are becoming more common in the construction of modern light aircraft, both manned and unmanned due to its exceptional workability, durability and long service life.
An integrated system that will use modern information technology in solving technological preparation is developed. For its implementation at the system level, new approaches using information technology, consisting in the choice of new methods for modeling and optimization, which can most effectively solve any technological problem, reduce the time s technological preparation to improve its quality.
Іn this paper a new approach to the basic parameters choice of controlled spherical liquid friction supports spatial mechanisms using the Monte Carlo method is developed. A jet system adjusts the position of the sphere by changing the hydrodynamic resistance to flow at the exit slit hydrostatic, or combined balloon aerohydrostatic spherical bearings.
