ML3020 PRINCIPLES OF METAL CUTTING L T P C
3 0 0 3
OBJECTIVE
Students are to learn about metal cutting operations from the theoretical and practical
perspective.
UNIT I CUTTING TOOL NOMENCLATURE 9
Single point tool-significance of the various angles - Machine reference system- normal
tool reference system- ORS – interrelation between different tool nomenclatures -
Nomenclature of drills, milling cutters and broaches
UNIT II CHIP FORMATION MECHANISM AND FORCES IN MACHINING 10
Orthogonal and oblique cutting - Mechanisms of formation of chips-types of chips -
Merchant's circle diagram-Force and Velocity relationship, shear plane angle, Energy
considerations in matching-Ernst Merchant’s theory of shear angle relationship - Forces
in turning, drilling, milling and grinding- specific cutting pressure-specific horse powerconstruction
and principle of operation of tool dynamometers for turning, drilling and
milling.
UNIT III THERMAL ASPECTS IN MACHINING, TOOL WEAR AND TOOL LIFE 10
Sources of heat generation in machining heat in PSDZ and SDZ – heat flow in cutting
tools temperature measurement techniques in machining, Functions of cutting fluid -
78
characteristics of cutting fluid-types - application of cutting fluids - Tool wear, type of tool
failure - mechanisms, tool life equation- tool life analysis - machinability - chatter in
machining.
UNIT IV CUTTING TOOL MATERIALS 8
Requirements of tool materials-properties of HSS - advances in tool materials- carbides
and coated carbides, ceramic, cermets, CBN, Diamond, PCD - ISO-specifications for
inserts and tool holders - -Need for chip breakers – types of chip breakers
UNIT V MODELING OF METAL CUTTING 8
Introduction to modeling – empirical models – mechanistic models – FEA based models
– artificial intelligence based models for turning, milling and drilling
TOTAL : 45 PERIODS
