Abstract
The geometry of the process oblique longitudinal turning tool with straight cutting edge is considered. The diagram of the process of oblique turning in a static system of coordinates, which takes into account the variability of the position of the coordinate planes along the cutting edge of the tool, is presented. The formulas that determine the geometry tool, which binds tool-in-hand and setting system of coordinates, are received. Values of angles for different values of the angle wedge are calculated. The variation of angles along the working part of the cutting edge of the value of the angle of inclination of the wedge and the reference plane is shown. On the diagrams of dependence of change of the geometry shows the operating range of the angle of the tool, limiting the area of the possible values of the slope angle of the main plane. Description of the method of modeling an equivalent wedge, for example, which visually shows the character of changes of geometry along the working part of the tool, is presented.
Keywords: oblique turning, peakless cutter, geometrical parameters, the inclination angle of the edge, the edge equivalent.
