AN3401 METAL CUTTING AND TOOL DEISGN L T P C
3 1 0 4
UNIT - I
Introduction: Definition of feed, depth of cut and cutting speed. Concept of specific cutting energy
in metal cutting and Numerical based on calculation of machining time on lathe, drilling machine,
shaper, milling machine and grinding machines considering specific cutting energy of materials.
Theory of Metal Cutting: Orthogonal and oblique cutting, types of chips, Factors affecting the chip
formation, Cutting forces in orthogonal cutting and their measurement, Merchant circle and derivation
of relationships between the cutting forces, chip thickness ratio, shear angle, stress and strain in the
chip, work done and power required in metal cutting, plowing forces and the ‘size-effect’, apparent
mean shear strength of work material.
57
UNIT - II
Ernst Merchant Theory:- its assumptions and modifications. Relationship between cutting velocity,
shear velocity and chip flow velocity. Mechanism of friction at chip-tool interface. Numericals based
on metal-cutting.
Heat generation in Metal cutting: Heat generation and temperature distribution in metal cutting.
Calculation of temperature in primary and secondary deformation zones and their measuring
methods.
UNIT - III
Machinability: Machinability and its criteria, forms of tool-wear in metal cutting, tool-life and its
criteria, effect of different cutting parameters on tool-life. Economics of machining and numericals.
Cutting fluids, their physical action and applications.
Grinding: Specifications of grinding wheel, Mechanics of grinding, effect of grinding conditions and
type of grinding on wheel behaviour, equivalent diameter of grinding wheel.
UNIT - IV
Cutting Tool Design: General considerations, single point tool geometry. Principles of different
cutting tool materials and their important characteristics. Geometry of a drill. Basic principles of
design of a single point and multiple point tools i.e broaches and twist drill.
UNIT V
