Geometric modeling of single point cutting tool surfaces

The metal undergoes shear type deformation and. The shear occurs along a plane called the shear plane. Actual separation of the metal starts as a yielding or fracture depending upon the cutting conditions. Deformed metal chip flows over the tool rake face. Friction between the tool rake face and the underside of the chip is considerable , then the chip gets further deformed i. Geometry of single point turning tools Single point: e. Concept of rake and clearance angles of cutting tools.

Concept of rake and clearance angle and its importance System of description of Tool geometry ASA, ORS and NSA systems Interrelation between different Systems of Nomenclature Tool geometry is basically referred to some specific angles or slope of the salient faces and edges of the tools at their cutting point. Both material and geometry of the cutting tools play very important roles on their performances in achieving effectiveness, efficiency and overall economy of machining. Cutting tools may be classified according to the number of major cutting edges points involved as follows: Single point cutting tools : Examples: turning tools, shaping, planning and slotting tools and boring tools Double or Two point cutting tools : Example : drills Multipoint more than two cutting tool: Example: Milling cutters, Broaching tools, Hobs, Gear shaping cutters etc. The geometry of a single point cutting tool is determined by the following features: Face or rake surface, which is the surface of cutting tool along which the chips move Flank surface that face the workpiece. There are two flank surfaces, namely principal and auxiliary flank surfaces. Cutting edge that remove material from the workpiece.

It is that part of a single point cutting tool which goes into the tool holder. Or in simple language shank is used to hold the tool. It is the surface below and adjacent to the cutting edges. There are two flank surfaces, the first one is major flank and the second one is minor flank. The major flank lies below and adjacent to the side cutting edge and the minor flank surface lies below and adjacent to the end cutting edge.
