BK7/K9 glass is regarded as a difficult-to-machine material due to its high hardness and high brittleness properties as well as high tool wear rate during machining. Facing to these challenges, an efficient and effective rotary ultrasonic machining (RUM) process, consisting of grinding process and ultrasonic machining process, was provided to process BK7/K9 glass. In this investigation, the effects of ultrasonic power on cutting forces, torque, and edge chipping of surface grinding in RUM of BK7/K9 glass were studied. Results showed that, by introducing ultrasonic vibration to surface grinding process, both cutting forces in feeding direction and in axial direction as well as torque values were reduced. The higher the ultrasonic power was, the lower the forces and torque values would be. Edge chipping, which was detrimental to the qualities of machined slots and would cause high machining cost, was significant reduced with the help of ultrasonic vibration.

Abstract. These days, in the manufacture of units and mechanisms of ships, aircraft and other technological machines, industrial robots, long-sized products from D 16 (Standart GOST-R) aluminum alloy are used, for the processing of which a complex for belt rotary grinding has been developed. The outcome measures of the rotary belt grinding process depend on the cutting forces generated during the processing process. According to cutting forces, process stability is diagnosed, values of surface roughness indices, temperatures and cutting modes are calculated according to displacement balance equation. The article is devoted to obtaining a mathematical model establishing the relationship between the tangential component of the cutting force and cutting modes during belt rotary grinding of D 16 aluminum alloy.

For the purpose of obtaining mathematical force model in grinding process, the contacting grain numbers and the single grain forces should be taken into considered. In this paper, a mathematical model was established for single grain forces calculation. A Matlab program is edited and the calculation results were obtained and discussed. In the work of this paper, only plowing and cutting forces were take into considered because that the sliding forces were proved to be neglected based on Hertz contact theory. Because of different micro-interacting mechanisms of plowing and cutting grains with workpiece material, different force models were developed separately.

Grinding process can be considered as micro-cutting processes with a lot of irregular abrasive grits on the surface of grinding wheel. The study of the grit-workpiece interaction through single grit cutting is an important contribution to describe the material removal processes in the grinding process. In this study, single grit cutting processes with different process parameters (depth of cut, cutting speed) were modeled by FEM software AdvantEdge. The critical depth of cut from plowing t cutting was investigated. The simulated tangential and radial cutting forces increase sharply due to the pile-up of workpiece material in the front of single grit when the depth of cut reached to some value. And the increase extent of cutting forces at low cutting speed is larger than that at high cutting speed due to the thermal softening of workpiece material. The simulated highest cutting temperature increase first, and then decrease, finally increase again with the increase of depth of cut. And the peak value of simulated highest cutting temperature occurs near the critical depth of cut. The simulated material removal rate increases with the increase of cutting speed and depth of cut.

The object of research is the process of circular and surface grinding of titanium alloy and corrosion-resistant steel, namely, the cutting forces arising from mechanical processing. One of the most problematic areas in work is the selection of the required grinding modes, material and grinding wheel grain size. In the course of the experiment, we used samples of VT8 titanium alloy and 12Х18N9T steel, on which the grinding process was studied with wheels made of various materials (electrocorundum, cubic boron nitride (CBN), diamond). The values of the cutting forces Py and Pz were obtained in the latitude of permissible modes, which are most often used in circular and flat grinding, and can reach maximum values, respectively, Py=27 N, Pz=15.5 N. The data were obtained at a low wheel speed from electrocorundum, about 15 m/s and grain size 8. By reducing the grain size of the wheel, we get the effect of increasing the energy consumption of the grinding process, due to the increase in the values of the cutting forces. If we compare the cutting forces arising from grinding with different wheels, then the following can be noted. Compared to electrocorundum wheels, when using CBN wheels, the cutting forces are reduced by 20–25 %, and when grinding with diamond wheels (despite the high wear of the diamond wheel), the effect of cutting forces is reduced by 25–30 %. This is due to the fact that cutting conditions are the most favorable for diamond and CBN grains, which makes it possible to use more intense cutting conditions. The results of the study allow predicting the performance of the grinding wheel, reducing the energy consumption of production, and also adjusting the processing mode of the part to obtain the necessary quality indicators of the surface layer and the geometric dimensions of the part.
