OBJECTIVE:
 To impart the knowledge on basic concepts of various machining processes and
machine tools
UNIT I LATHE 9
Introduction to production processes – types of production (job, batch and mass) –
production processes – Casting, Forming, Machining and Welding, Machine and Machine
Tool – Lathe – Engine Lathe – block diagram – sketch – functions of each part – work
holding devices in lathe – functions – Chuck, Centre, Dogs, Steady Rest and Follower
Rest, mechanism of lathe – Apron, Feed, Tumbler Gear, various operations performed in
Lathe – facing, turning, chamfering and knurling – relative positions of tool and job –
Taper turning operations (three methods_ thread cutting – thread – RH and LH, single
start and multi start with application – Method of thread cutting – selection and
arrangement of tool and work. Problems in metric and inch thread conversion –
Specifications of Lathe – Burnishing.
UNIT II SHAPER, PLANER & SLOTTER 9
Purpose of shaping – block diagram – functions of each part. Purpose of planer – block
diagram – functions of each part. Purpose of slotting machine – block diagram –
functions and working principle. Operations carried out – horizontal plane, vertical plane,
v type with relative position – Comparison of planer with shaper – work holding devices in
shaper and planer – Quick return mechanism in shaper – mechanical and hydraulic –
cross feed mechanism –Types of planer with application – mechanism in planer –
Comparison of shaping with slotting – tool holding devices in shaper, planer and slotter –
specifications of shaper, planer and slotter simple problems to calculate the velocity –
speed, feed and depth of cut.
UNIT III DRILLING 9
Purpose of drilling – block diagrm and function – types of drilling machines – portable
drilling – bench type – sensitive drilling – radial arm drilling – functions of parts – purpose
and operation – gang milling, multiple drill head, upright drilling, relative operations –
reaming, boring, tapping, counter boring, courses sinking, trepanning and spot facing
(with simple sketch, purpose and application). Work holding devices – specification
torque calculation – speed, feed and depth of cut.
24
UNIT IV MILLING 9
Milling machine purpose – up and down milling – classification of milling machines – slot,
keyway machining – methods of milling – single piece, string, rotary, index, gang,
progressive, copy. Horizontal milling machine – block diagram – functions of each partapplications
– Vertical milling machine – block diagram – functions of each part
applications – Gear cutting using milling machine – procedure with neat sketch – milling
cutters – peripheral, face, end T slot, form etc. – attachments and special accessories for
milling – rotary, slotting attachment – indexing mechanism – methods of indexing – direct,
plain, compound and differential indexing – problems – specifications – cutting conditions
and parameters.
UNIT V GRINDING 9
Purpose – classification – surface finish – applications – grinding wheel – types –
specifications – selection – surface grinding machine – block diagram – functions of each
part – cylindrical grinding – Centreless grinding – Comparison – infeed, end feed and
through feed. Balancing, dressing, loading and Truing of wheel – special grinding
machines – specification of machine – cutting condition.
For all machines, demonstration to be done in a Workshop or using CD to explain the
actual operation.
