“…Mikolajczyk et al [18] uses the name "oblique turning" and presents new, original constructive solutions of special tools with continued edge and high value of cutting angle λs, for which patent protection was requested [19]. The name "oblique turning" is also used by Filippov [20]. To avoid ambiguities, it is expected that the name "tangential oblique turning" proposed by the authors of the present paper will be imposed.…”

The quality of the surfaces is an important characteristic pursued when processing the parts used in the construction of machines. There is a constant search for new, original processing schemes and tools, which lead to the best possible results. For this, the authors have designed an original lathe tool, with inclined tangential cutting edge with adjustable inclination, for which a patent application has been submitted. By using this tool, a large number of tests with representative processing parameters were performed on 42CrMo4QT steel specimens, considering a complete research plan. All tests were performed with the same depth of cut, but different speeds, feed rates and inclination of the cutting edge of the tool. The roughness of the obtained surfaces was measured using a high-performance electronic roughness meter. For comparison, processing under similar conditions was performed using a normal turning tool. The present paper presents a mathematical model for the theoretical roughness in turning with an inclined tangential edge, analyses the influence of the working parameters on the roughness and compares the ideal values with values obtained experimentally.

Predictive force models for oblique metal cutting incorporating tool flank wear was carried out using a CNC lathe machine to turn mild carbon steel CS1030. The developed models are based on the fundamental mechanics of orthogonal cutting process, in which inclination angle is 0°. Workpieces were Cylindrical with wall thickness of 3mm and diameter of 100 mm. Cut thickness levels were 0.1, 0.17, 0.24 and 0.31 mm; cutting speeds were 100, 150 and 200 m/min; tool rake angle levels were −5, 0 and 5°. wearland sizes were selected as 0, 0.2, 0.4, 0.6 mm, where wearland size "0 mm" represents sharp tool. Results of the study indicate that tool flank wear has significant effect on oblique cutting forces. The oblique cutting forces were found to increase linearly with tool flank wear due to rubbing or ploughing forces in the wearland. The results also show that, the measured experimental oblique forces (power force, Fcm thrust force Ftm and rubbing force Frm) agreed with the predicted (power force Fc thrust force Ft,and rubbing force Fr) values under the corresponding cutting conditions. It is evident from the plots that the models give an excellent prediction of the cutting forces during oblique cutting.

In today's unmanned productions systems, it is very important that the manufacturing processes are carried out efficiently and smoothly. Therefore, controlling chip formation becomes an essential issue to be dealt with. It can be said that the material removal from a workpiece using machining is based on the degradation of material cohesion made in a controlled manner. The aim of the study was to understand the chip formation mechanisms that can, during uncontrolled processes, result in the formation and propagation of microcracks on the machined surface and, as such, cause failure of a component during its operation. This article addresses some aspects of chip formation in the orthogonal and oblique slow-rate machining of EN 16MnCr5 steel. In order to avoid chip root deformation and its thermal influence on sample acquisition, that could cause the changes in the microstructure of material, a new reliable method for sample acquisition has been developed in this research. The results of the experiments have been statistically processed. The obtained dependencies have uncovered how the cutting tool geometry and cutting conditions influence a chip shape, temperature in cutting area, or microhardness according to Vickers in the area of shear angle.
