For all other machine tools 5th sem syllabus for diploma m scheme tndte you can visit Machine Tools 5th Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for engineering metrology is as follows.
Rationale:
The exponential growth of engineering industries has made a vide scope for maintenance engineering. The student studying maintenance should have a thorough knowledge in various aspects of Metrology
Objectives:
- To know the Limits, Fits And Gauges:
- To know the Straightness, Flatness, Squareness, Parallelism, Circularity And Rotation
- To know about Angular Measurement And Surface Finish
- To know about Comparators And Non Destructive Testing
- To about Transducers

Unit 2
Straigtness, Flatness, Squareness, Parallelism, Circularity And Rotation:
Straightnessdefinitions – straight edge- tests for straightness by using spirit level – auto collimator – flatness testing- procedure. Parallelism-two axis – two planes- parallel motion between trajectory and plane – trajectory to an axis two trajectories – equidistancecoincidence or alignment. Square ness – axis of rotation with a given plane – perpendicularity of motion- square ness testing -indicator method- correction for square ness error – engineer’s square tester- optical tester for square ness – Optical test for square ness – Circularity – sources of out of roundness -different types of irregularities of a circular part – causes of out of roundness – roundness and circularity – measurement of roundness by using V block – Test for checking rotation – run out
Unit 3
Angular Measurement And Surface Finish:
Instruments for angular measurement- venire and optical level protractor- universal bevel protractors optical dividing head- angle gauges- use of angle gauges-manufacture of angle gauges- spirit level clinometers – auto collimator- photo electric micro tic auto collimator- automatic position sensing auto collimator- angle Decker- uses of angle Decker in combination with angle gauges.
