Increase of efficiency cutting machining of cold-resistant steels by automatic calculation of the rational cutting modes
Аннотация
Researches of influence of cutting parameters (speed of cutting, cutter feed and cutting depth ) on cutting power are considered at edge cutting machining of a cold-resistant steel 10GNB. On the basis of researches multifactorial models of firmness of the cutting tool are received. By the received results REZMET the technique and system of the automated calculation is developed for definition of optimum cutting parameters of cold-resistant steels.

Operation features of two-stage injection proces in diesiel fuel system
Аннотация
This work is dedicated to phase fuel injection research and double-spring injectors of diesel engines design analysis. It is known that preliminary fuel injection in diesel engines leads to noise reduction but at the same time soot emission increase noted. Article contains design analysis of injectors with two needles, application of which is perspective and effective in domestic diesel engines.
