The issues of the components of a grinding wheel recipe, namely, abrasive grains, bonds and various fillers on the cutting forces during grinding are considered in the article. The following types of fillers were studied: fused alumina microspheres, which are a non-burning hollow filler, glass microspheres used as a hollow melting filler, and a burning filler in the form of crushed fruit pits. On the basis of the obtained experimental data, generalized statistical models of the dependence of the magnitude of cutting forces during grinding on the percentage of grains, bond and fillers were developed. From the analysis of the pair correlation coefficients of the models of the grinding force components, it was concluded that the percentage of grains, bond, glass microspheres have the strongest effect on the cutting force sand the effect of fused alumina microspheres and fruit pits is negligible. Based on the results obtained, conclusions are formulated in the form of practical recommendations for reducing cutting forces.

“…Из-за изменения диаметра лепесткового круга от частоты вращения особый интерес представляет характер контакта круга с обрабатываемой поверхностью. При этом изменение диаметра сопровождается деформацией круга в зоне контакта с изменением траектории движения лепестков [9][10][11][12][13][14][15][16]. Всё вышеуказанное приводит к сложной картине формирования шероховатости поверхности в зоне зачистки, которая, в свою очередь, зависит еще и от технологических параметров, характеристик инструмента и физико-механических свойств материала обрабатываемой детали.…”

In order to obtain the necessary shape of long panels and sheaths, the aircraft industry successfully uses a complex technology of shaping. Grinding, as an operation in a complex technological process, is provided after the operation of shot-peen forming before hardening. It is designed to ensure that the roughness and final aerodynamic shape of the surface meet the requirements established by the drawing of the part. To implement this technology, a special installation UDF-4 (shot-impact forming unit) was designed and manufactured at the Irkutsk National Research Technical University. The version of this installation was equipped with a CNC system and a revolver stripping head with 4-flap wheels. The possibility of choosing the necessary flap wheels in the process of grinding, depending on the curvature and width of the treated surface, significantly expanded the technological capabilities of the installation. The elastic abrasive flap wheels of a straight profile used in production have proven themselves well both in terms of grinding performance and tool durability. However, practice has shown that due to the complex impact of abrasive petals during contact with the treated surface, a special zone of uneven impact along the length of the contact of the petals is formed during grinding. The results of experimental studies have shown that the roughness of the treated surface is significantly improved when the direction of movement of the flap wheels feed in the contact zone is changed from oncoming to passing. The paper presents experimental data on studies of changes in surface roughness in the contact zone with the abrasive flap wheels during grinding, depending on the processing modes, as well as the results of an experimental study of the quality of the treated surface with counter and passing feed.

The paper aims to study the stress-strain state of the surface layer in a VT95 aluminum alloy part during its shot-impact treatment in the sequence of “shot-impact treatment–flap-wheel trimming” operations. The research objects included large parts, such as panels and cladding of complex shapes used in aircraft, missile, and shipbuilding industries. Computer simulation in the Ansys Workbench 19.0 software package was used to develop a methodology for determining residual stresses. As a result of simulating the studied treatment sequence, a visual representation of the residual stress formation pattern, as well as physical values and distribution curves of residual stresses, were obtained. The distribution pattern of residual stresses after performing two types of treatment was established to be similar. The maximum value of residual stresses, obtained as a result of performing a shot-impact treatment of the part surface with a shot of 3.0 mm in diameter at a shot-impact rate of 25 m/s, reaches about 600 MPa at a depth of 1.0 mm. Following the shot-impact treatment, flap-wheel trimming is performed in the finite element simulation as a set of abrasive grains at a rate of 18.316 m/s. The removal of the 25-, 50-, and 75-μm layer from the surface of the plate during trimming contributes to the shearing of the upper part in the residual stress diagram and, as a result, to a decrease in the values of residual stresses in the shot-impact treatment–flap-wheel trimming sequence to 400 MPa. In addition, along with an increase in the thickness of the layer removed from the surface during trimming, the value of residual stresses decreases more slowly. In this case, the thickness of the removed layer causes no effect on the depth of residual compression stresses (about 0.7 mm). The developed finite element model makes it possible to predict and control the level and magnitude of residual stresses in an aluminum alloy sample at the stage of its preparation for both a shot-impact treatment operation and the combination of shotimpact treatment and flap-wheel trimming.
