1 THEORY OF METAL CUTTING
2 INTRODUCTION Overview of Machining Technology Mechanism of chip formation Orthogonal and Oblique cutting Single Point and Multipoint Cutting Tools Machining forces - Merchant s Circle Diagram Thermal aspects of metal machining Cutting fluids Machinability - Cutting tool materials Tool wear and Tool life calculations.
3 A family of shaping operations, the common feature of which is removal of material from a starting workpiece so the remaining part has the desired shape Machining Material removal by a sharp cutting tool, e.g., turning, milling, drilling Abrasive processes Material removal by hard, abrasive particles, e.g., grinding Nontraditional processes - Various energy forms other than sharp cutting tool to remove material
4 Machining Operations Most important machining operations: Turning Drilling Milling Shaping and planning Broaching Sawing Machining Operations
5 Turning Drilling Milling

7 Mechanism of chip formation Metal ahead of the cutting tool is compressed and this results in the deformation or elongation of the crystal structure resulting in a shearing of the metal. As the process continues, the metal above the cutting edge is forced along the chip-tool interference zone and is moved away form the work. Cutting action involves shear deformation of work material to form a chip. As chip is removed, a new surface is exposed
8 Showing shear zone rather than shear plane. Also shown is the secondary shear zone resulting from tool-chip friction
9 Types of chips Continuous chip Discontinuous chip Continuous chip with Built-up Edge (BUE)
10 Continuous Chip Ductile work materials (e.g., low carbon steel) High cutting speeds Small feeds and depths Sharp cutting edge on the tool Low tool-chip friction
11 Discontinuous Chip Brittle work materials (e.g., cast irons) Low cutting speeds Large feed and depth of cut High tool-chip friction
12 Continuous with BUE Ductile materials Low-to-medium cutting speeds Tool-chip friction causes portions of chip to adhere to rake face BUE formation is cyclical; it forms, then breaks off
13 Forces Acting on Chip Friction force F and Normal force to friction N Shear force F s and Normal force to shear F n Forces acting on the chip in orthogonal cutting
14 Coefficient of Friction Coefficient of friction between tool and chip: F N tan Shear Stress Shear stress acting along the shear plane: S F A s s A s tow sin where A s = area of the shear plane
15
16 Orthogonal and oblique cutting Orthogonal Cutting (2-D Cutting): Cutting edge is straight, parallel to the original plane surface at the workpiece and perpendicular to the direction of cutting. E.g. Operations: Lathe cut-off tools Straight milling cutters etc. Oblique Cutting: Cutting edge of the tool is inclined to the line normal to the cutting direction. In actual machining, Turning, Milling etc cutting operations are oblique cutting.

19 Single-Point Tools One cutting edge Turning uses single point tools Point is usually rounded to form a nose radius Multiple Cutting Edge Tools More than one cutting edge Motion relative to work usually achieved by rotating Drilling and milling use rotating multiple cutting edge tools.

25 Forces of a Single Point Tool Cutting Conditions in Machining The three dimensions of a machining process: Cutting speed v primary motion Feed f secondary motion Depth of cut d penetration of tool below original work surface For certain operations, material removal rate can be found as MRR = v f d where v = cutting speed; f = feed; d = depth of cut
26 Cutting Conditions for Turning Figure Cutting speed, feed, and depth of cut for a turning operation
27 The work material offers a resistance to the cutting tool during metal cutting. This is overcome by the cutting force applied to the tool face. The magnitude of cutting force depends upon following factor : Material Rate of feed Depth of cut Tool angle Cutting speed Coolant
