“…There are two approaches to the definition of cutting layer thickness:  a kinematic approach considers the cut geometry in the plane normal to the cutting surface (Yeroshenko, 2009;Stepien, 2007), asking the average distance between the cutting edges;  a volumetric approach involves determining of the average volume of the slice and taking its shape and the average number of cutting edges on one surface of the wheel, finding its thickness (Yeroshenko, 2009;Kalchenko et al, 2012). When calculating the cutting layer thickness it is necessary to provide cutting of all material that is fed into the processing zone.…”

Abstract:In the work the analysis of existent methods of determination of local and general forces of cutting at polishing of surfaces with a type as the arc of circumference is given. The dependence for determination of speed polishing and method for determination of thickness of the cut away layer on condition of equality of the tricked into and taken off volumes of material are offered. The method of determination of cutting forces, which takes into account cutting and deforming grain, is suggested. The method of determining the thickness of a cutting layer of one of the cutting edge, from the condition that the volume of material that is brought and is cut in each local point of contact spots has been proposed. The proposed method takes into account the compliance of the processing system and the discontinuity of the abrasive surface of the tool. By experimental way upper limits of thickness cutting layer when using different abrasive materials for a wide range of cutting speeds have been obtained.

“…The first one is the creep feed grinding (CFG), in which a highly porous, conventional grinding wheel machines the workpiece with very high depths of cut (in some cases, up to even 20 mm) and low feed rates. The process is used in the aerospace and automotive industry in machining difficult-to-cut materials such as superalloys and refers mainly to surface grinding, although can also be used in cylindrical grinding [6,7]. The second one-pass method -known as traverse contour grinding or continuous path-controlled grinding (CPCG) -is recognised as an alternative to hard turning and consists of using a narrow cylindrical grinding wheel (cBN), which follows the shape of the workpiece [8][9][10].…”

The article presents a method of increasing the shape and dimensional accuracy of low-stiffness shafts manufactured in a single pass of a grinding wheel in traverse grinding. One-pass manufacturing is one of the ways for reducing machining time and increasing efficiency, thus lowering production costs. However, maintaining the necessary accuracy proves to be a challenge because the whole machining allowance has to be removed at once, leaving no room for errors that could be fixed in additional passes of the tool. It is especially true in finishing operations, such as traverse grinding. In addition, grinding the workpiece in a single pass of a grinding wheel leads to high forces, which cause elastic deformation of the part. The lower the stiffness of the part, the more difficult it is to achieve the required accuracy. As a result, there are many methods of improving the accuracy of grinding such parts, but they tend to be either expensive or reduce the machining efficiency. Thus, it is important to seek new methods that would allow improving the accuracy of the machining without reducing its efficiency. The proposed method does not require using steady rests and is based on the measurement of the normal grinding force component. Knowing the value of the grinding force when grinding with a set grinding depth, the elastic deformation of the machine tool–tool–workpiece system is calculated in each position of the grinding wheel. Based on the calculated deformation, the additional infeed of the grinding wheel is implemented in order to stabilise real grinding depth and to increase the accuracy of the produced part. The experimental tests were conducted to prove the effectiveness of the proposed method.
