PR8301 BASIC MACHINING PROCESS

UNIT I LATHE 

Introduction to production processes – types of production (job, batch and mass) –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 AND SLOTTER 

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 

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.

UNIT IV MILLING 

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 

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.
