Orthogonal and Oblique Cutting | Mechanics of Machining

Orthogonal and oblique cutting It is appears from the diagram in Fig. Ideal direction of chip flow in turning that while turning ductile material by a sharp tool, the continuous chip would flow over the tool’s rake surface and in the direction apparently perpendicular to the principal cutting edge, i.e., along orthogonal plane which is normal to the cutting plane containing the principal cutting edge. But practically, the chip may not flow along the orthogonal plane for several factors like presence of inclination angle, λ, etc. Figure: Ideal direction of chip…
