“…Comparison of the results can be used to verify the correctness of the calculations. Such a small angle of rise of the main hob allows you to ignore it and make a straight-toothed tool, thus ensuring maximum simplicity of its regrinding on the front surface (Kudinova et al, 2016).…”

The article shows the possibility of designing and manufacturing using multi-coordinate grinding and sharpening machines with CNC for workable worm mills for machining straight-slotted slots. Screw backing provides the necessary values of the rear side corners, and the ability of CNC machines to achieve the required accuracy and manufacturability of the tool. The lack of such tools consists in the increase of the diametrical sizes in comparison with the classically used ones. A positive effect when using the principles of screw backlash is the shaping of the cutting edges of the teeth in a checkerboard pattern, which significantly reduces the cutting forces. The use of techno-logical 3D models as a result of the design allows, at the design stage, to evaluate the arising design flaws and to make the necessary corrective actions into the initial data of the tool.

“…Все урав-нения пишутся либо для однородного материала, либо для композита, состоящего из вкраплений одного материала в матрицу другого. Между тем установлено, что при пластическом деформи-ровании поликристаллических материалов большую роль играют силы поверхностного натяже-ния или поверхностные силы кристаллитов [9]. Таким образом, необходимо учитывать наличие поверхностного слоя с особыми свойствами.…”

A new model of instability of uniform plastic deformation with the formation of Lüders bands on the surface of a material being deformed is experimentally confirmed. It has been found that nonuniform plastic deformations correlate with hydrogen concentration during the testing of metal specimens in the atmosphere at room temperature. The presence of additional pores and microcracks formed as a result of plastic deformation is the cause of the correlation between plastic deformations and hydrogen concentrations in aluminum alloys. The effect of the boundary layer in the distribution of hydrogen concentrations has been detected. It reflects the fact that all changes associated with mechanical and thermo-mechanical loading are localized in a thin boundary layer at the surface of a metal specimen. The wave approach to the analysis of the continuum equations and the model of the boundary layer of a bicontinuous medium containing hydrogen are used to describe the observed phenomena. The constructed model makes it possible to describe the development of plastic deformation as a wave process in the boundary layer of a bicontinuous medium. Paris, 1923, vol. 176, pp. 507-510. 4.
