 L T P C

3003

OBJECTIVE:
• To impart the knowledge on basic concepts of various machining processes and machine tools.
• To impart the knowledge on basic concepts of mechanics in metal cutting process.
• To impart the mechanism involved in tool wear.

UNIT I

LATHE

9

Introduction to production processes – types of production (job, batch and mass) – production processes – Lathe – Engine Lathe – block diagram – sketch – functions of each part – work holding devices in lathe various operations performed in Lathe – facing, turning, chamfering and knurling – relative positions of tool and job – Taper turning operations – Method of thread cutting – selection and arrangement of tool and work.

UNIT II

SHAPER

9

Purpose of shaping – block diagram – functions of each part, work holding devices in shaper - Quick return mechanism in shaper – mechanical and hydraulic – cross feed mechanism – simple problems to calculate the velocity – speed, feed and depth of cut.


UNIT III

DRILLING

9

Purpose of drilling – block diagram and function – types of drilling machines – portable drilling – bench type – sensitive drilling – radial arm drilling. Work holding devices – specification torque calculation – speed, feed and depth of cut.

UNIT IV

MECHANICS OF METAL CUTTING

9

Cutting tool angles – tool signature – orthogonal & oblique cutting – cutting forces, Merchant circle diagram – force & velocity relation.

UNIT V

TOOL MATERIAL, TOOL WEAR, TOOL LIFE AND MACHINABILITY

9

Requirement of tool materials – types of tool materials – Tool wear – Types, mechanism – Tool life - Machinability - types of chips – Types of cutting fluids.

TOTAL: 45 PERIODS

OUTCOMES: At the end of the course, the students will be able to:
1. Understand the constructional features and working principles of Lathe, work holding devices and also understands the concepts of mechanics of metal cutting.
2. Understand the constructional features and working principles of shaper, work holding devices and various machining operations performed.
3. Understand the constructional features and working principles of drilling machine and its types.
4. To apply the principles of metal cutting and mechanics in machining process.
5. To select tool materials based on requirement.
