JNTUK B.Tech Machine Tools & Metrology gives you detail information of Machine Tools & Metrology R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objectives: The students completing this course are expected to understand the concept of various working principles of various machine tools and concepts of metal cutting. Further there are exposed to the importance of metrology.
UNIT – I : Objective: The fundamentals of metal cutting and forces involved will be given enough exposer to the student. Elementary treatment of metal cutting theory – element of cutting process – geometry of single point tool angles, chip formation and types of chips – built up edge and its effects chip breakers, mechanics of orthogonal cutting –Merchant’s force diagram, cutting forces, cutting speeds, feed, depth of cut, tool life, coolants, tool materials.
UNIT – II : Objective: the students are to be exposed the fundamental concepts of Engine Lathe and its various operations that can be performed. Engine Lathe :– principle of working, specification of lathe – types of lathe – work holders tool holders – operations performed- box tools taper turning, thread turning – for lathes and attachments, turret and capstan lathes – collet chucks – other work holding – tool holding devices. Principal features of automatic lathes classification – single spindle and multi-spindle automatic lathes.
UNIT – III : Objective: the students are to be exposed the fundamental concepts of Shaping, Slotting, and Planning, Drilling and boring machines and its various operations that can be performed Shaping, slotting and planning machines: Principles of working – principal parts – specifications, operations performed, machining time calculations. Drilling & Boring machines: Principles of working, specifications, types, operations performed – tool holding devices – twist drill – Boring Machines – jig boring machine, deep hole Drilling Machine.
UNIT – IV : Objective: the students are to be exposed the fundamental concepts of Milling machines, grinding machines and its various operations that can be performed Milling machine: Principles of working – specifications – classification of Milling Machines – machining operations, types of cutters and geometry. Grinding: Theory of grinding – classification of grinding machines, different types of abrasives, bonds, specification and selection of a grinding wheel. Lapping, Honing & Broaching operations, comparison to grinding.
UNIT-V : Objective: The students are to be exposed to the fundamental concepts and systems of limits and tolerances and measurement instruments.
SYSTEMS OF LIMITS AND FITS: Introduction, nominal size, tolerance, limits, deviations, fits and their types-unilateral and bilateral tolerance system, hole and shaft basis systems- interchangeability. Linear measurement: Length standards, end standards, slip gauges- calibration of the slip gauges, dial indicators, micrometers. Measurement of angles and tapers: Different methods – bevel protractor, angle slip gauges- clinometer Limit gauges: Taylor’s principle – design of go and no go gauges; plug, ring, snap, gap, taper, profile and position gauges.
UNIT-VI : Objective: The students are to be exposed the fundamental concepts of optical measuring instruments and surface measurement instruments Optical measurement instruments: Tools maker’s microscope and uses – collimators, optical projector, optical flats and their uses. Surface roughness measurement: Differences between surface roughness and surface waviness. Comparators: Types – mechanical, optical, electrical and electronic, pneumatic comparators and their uses
Course outcomes: The students completing the course will be able to understand the various machines tools and their operating principles and various precision measuring procedures.
