  • EXPERIMENT NO: - 01Aim: - Linear Measurement Using Vernier Height Gauge & Micrometer (Internal & External Depth)Apparatus :- Vernier Caliper, Vernier Height Gauge, Micrometer, And Measuring PartsVernier Height Gauge This is just as vernier caliper, equipped with special base block and otherattachment which make the instrument suitable for height measurements. Along with thesliding jaw assembly, arrangement is provided to carry a removable clamp. The upperand lower surfaces of the measuring jaws are parallel to the base, so that it can be usedfor measurements over or under surface. The vernier height gauge is mainly used in theinspection of parts and work. With a scribing attachment in place of measuring jow, thiscan be used to scribe lines at certain distance above the surface. However dial indicatorCan also be attached in the clamp and many useful measurements made as it exactlygives indication when dial tip just touching surface. For all these measurement, use ofsurface plate as datum surface is very essential.PROCEDURE-1. Take the material (sample) for which the value must be measured.2. Check the vernier and main scale must coincide at 03. After checking the 0 mark put the sample piece and slowly leaves the measuring jawover the piece4.

  • 23MICROMETER The end of the screw forms one measuring tip and the other measuring tip isconstituted by a stationary anvil in the base of the frame. The screw is threaded forcertain length and is plan afterwards. The plain portion is called sleeve and its end is themeasuring surface. The spindle is advanced by turning thimble connected to the spindle.The spindle is aside fit over the barre land barrel is the fixed part attached with frame.The barrel is graduated in unit of 0.05cm.i.e.20division per cm, which is the lead of thescrew for one complete revolution. The thimble has got 25 divisions around its peripheryon circular portion. Thus it sub-divides each revolution of the screw in 25 equal parts;i.e.each division corresponds to 0.002cm.PROCEDURE1. The whole movable jaw assembly is adjusted so that the two measuring tip just touchtwo parts to be measured.2. Then lock nut is tightened.3. Final adjustment depending upon the sense of correct feel is made by the adjustingscrew.4.

Note down reading by following procedure.OBSERVATION TABLESr No MSR VSR LC TSR12345RESULTLinear measurement using vernier caliper, vernier height gauge and micrometer (internaland external depth) are successfully completed.
  • EXPERIMENT NO 2Aim:- Angular measurement using Combination Set, Bevel Protractor , Sine Bar andClinometers.Apparatus :- Combination Sets, Bevel Protector, Sine Bar and Clinometers.TheoryBEVEL PROTECTOR It is use for measuring &lying out of angles accurately and precisely within 5minutes. The protector dial is slotted to hold a blade which can be rotated with dial to therequired angle and also independently adjusted to any desired length. The blade can belocked in any position.
  • SINE BARThe sine principle uses the ratio of the length of two sides of a right triangle in deriving agiven angle. It may be noted that devices operating on sine principal are capable of selfgeneration. The measurement is usually limited to 45 degree from loss of accuracy pointof view. The accuracy with which the sine principle can be put to use is dependent inpractice, on some from linear measurement. The sine bar itself is not complete measuringinstrument. Another datum such as surface plate is needed, as well as other auxiliaryinstrument, notably slip gauge, and indicating device to make measurements.Checking of Unknown Angles :- Many a times , angle of component to be checked isunknown. In such a case it is necessary to first find the angle approximately with the helpof a bevel protractor. Let the angle . Then the sine bar is set at an angle () and clamped toan angle plate. Next the work is placed on sine bar and clamped to Angle plate as shownin figure. Slip –gauges are so arranged ( according to deviation) that the sprit level is atcenter ( the air bubble ) If the deviation is noted down by the spirit level is h over a length ‘l’ of work ,then height of slip gauges by which it should be adjusted is equal to = h 1
  • Precaution In Sine Bars :-(a) A Compound angle should not be formed by miss dignity of w/p with the sine bar. This can be avoided by attaching the sine brand work against an angle plate.(b) Accuracy of sine bar should be ensured.(c) As far as possible longer sine bar should be used since4 many errors are reduced by using longer sine bar.Combination Sets :-The combination set consists of scale , squaring-head, protractor and center-head. Itconsists of a heavy scale , which is grooved all along it’s length . It is on this groove thatsliding squaring head is fitted . One surface of the squaring head is always perpendicularto the scale and it can be adjusted at any place by the locking bolt and nut. The squaringhead also contains a spirit level which is used to test the surfaces for parallelism. Forlaying out dovetails an included angle is also mounted on the scale . It can also slide toany position and be locked there. A scribing point is also inserted into the rear of the basefor scrubbing purposes. The squaring head and scale can be used for height and deptmeasurement, inside and outside squaring operation.
  • COLINOMETERSA clinometers is a special case of the application of spirit level in colinometer; the spiritlevel is mounted on a rotary member carried in housing. One face of the housing formsthe base of the instrument. On the housing, there is a circular scale. The angle ofinclination of the rotary member carrying the level relative to its base can be measured bythis circular scale. The clinometers is mainly used to determine the included angle of twoadjacent faces of work piece. Thus for these purpose, the instrument base is placed onone face and the rotary body adjusted till zero reading of the bubble is obtained. Theangle of rotation is then noted on the circular scale against the index. A second reading isthen taken in the similar manner on the second face of work piece. The included anglebetween the faces is then the difference between the two readingsPrecautions :- 1. Angle of instrument must coincide with the angular scale 2. Gripped the instrument to the measuring face exactlyResult :-
  • To Perform angular measurement using sine bare with slip gauge study ofclinometers , angle , gauge , combination set and bevel protractor is successfullycompleted EXPERIMENT NO:- 03AIM :- Measurement Of Screw Thread Diameter Using The Floating flat form.Measuring machine.Apparatus :- floating platform device, screwed or threaded specimen.FLOAING CARRIAGE MEASURING MACHINE: Measuring machine shown in the fig. Consists of three main units. First basecasting carries a pair of centers on which a threaded work piece is mounted. Anothercarriage called as lower late is mounted on base. Which is exactly at 90 degree to basebut capable of moving parallel with the axis of thread. On this lower slide is providedwith another. Carriage called as top slide and capable of moving towards the center (i.e.
  • 90 degree to the thread axis) on the one and f top slide there is one head having a largethimble inability to read up to 0.002 mm and on the other and just opposite to it is a fixedanvil which is spring loaded and its zero position is indicated dry fidrcial indicator. Onthis top slide two supports one provides for supporting were and viz pieces formeasurement of minor dial and effect diameter.WORKING:- Place the standard cylinder (gauge) whose diameter is approximately equal ornearer to the major diameter of extend thread which can be adjust between two center offixed carriage or base.The distance between centers can be adjust with the help of jigs provide. After this movethe lowerSlide parallel to axis of cylinder so as take the leadings at correct position. Now stopmoving lower slide and operate the thimble of micrometer by engaging viz pieces overflat anvils to get a constant reading of financial indicates of top slide. When you see thatindicate is set a fixed-point note down the reading (h) of micrometer. Take the reading forthe standard gauge of fixed dimension which will be indicated as R1.R1 = M.S.R. + (VSR 1 * L.C 1) + (VSR2 * LC2) ------------------ [1]
  • Replace the standard cylinder with threaded work piece and repeat the same procedureand see to it that the fiducially indicator is showing the same reading as it was in earliercase. If it is so stop moving the thimble considering constant pressure is applied in boththe case. Note down the reading.R2 = M.S.R. + (VSR1 * L.C 1) + (VSR2 * LC2) ------------------ [2]Major diameter = D + (R2-R1) if R2 > R1 = D - (R1-R2) if R2 < R1Where D - is dial of setting standard cylinder. Same procedure is again repeated by inserting wire of given diameter in theconsecutive threads of the given job by keeping all the dial indicator setting as constantand take that reading as R3. R3 = M.S.R. + (VSR1 * L.C.1) + (VSR2 * LC2) --------------- [3]Let M is the diameter with wire then. M = 25 - (R3 - R1) if R3 > R1 --------------------------------[4] = 25 + (R1 - R3) if R3 < R1 --------------------------------[5] Floating carriage micrometer is the best method to determine the affectivediameter of up to four decimal place. This method is divided into two types according tono. Of wires:- 1) Two wire method 2) Three wire method For, two wire method the wire diameter’d’ and content pitch are calculated as BM = 1/2 BC = 1/2 {p/2} = p/4Let, M = distance over wire E = effective diameter D = diameter of wire X = angle of threads P = pitch of threads

  • Experiment no :4Aim - Measurement of threads parameters using tool makers microscope.Apparatus :- Tool makers microscope, threading job.Tool makers microscope :- Tool makers microscope is versatile instrument that measures by optical meanswith no pressure being involved it is thus a very useful instrument for makingmeasurements on small and delicates parts. The tool makers microscope is designed forthe following measurements; measurements on parts of complex form for example, theprofile of external thread as well as for the tools, templates and gauges, measuring centreto centre distance of holes in any plane and other wide variety of linear measurementsand accurate angular measurements. A tool makers microscope is as shown in fig. The optical head can be moved upor down the vertical column and can e clamped at any height by means of a clampingscrews. The table which is mounted n the base of the instrument can be moved in twomutually perpendicular horizontal directions (longitudinal and lateral) by means ofaccurate micromeres screws having thimble scale and venires. A ray of light from light source (fig - 2) is reflected by mirror through 90. It isthen passes through a transparent glass plate (on which flat parts may be placed). Ashadow image of the outline or contour of the work piece passes through the objective ofthe optical head and is projected by a system of three prisms to ground glass screen.Observations are made through an eyepiece. Measurements are made by means of cross-lines engraved on the ground glass screen. The screen can be rotated trough 360 the angleof rotation is read through an auxiliary eyepiece.
  • Procedure:-The use of - tool makers microscope for the taking the various measurements isexplained below- 1) For taking linear measurements, the work piece is placed over the table. Themicroscope is focused and one end of the work piece is made to coincide with cross linein the microscope (by operating micrometers screws). The table is again moved until theother end of the work piece coincide with the cross line on the screen and the finalreading taken. From the final reading, the desired measurement can be taken. 2) To measure the screw pitch, the screw is mounted on the table. The microscopeis focused (by adjusting the height of the optical head) until a sharp image of theprojected contour of the screw is seen of the ground glass screen. The contour is set sothat some point on the contour coincides with the cross line on the screen. The reading onthe thimble of the longitudinal micrometer screw is noted. Then the table is moved by thesame screw until a corresponding point on the contour (profile) of the next threadcoincides with the cross line. The reading is again noted and the difference in two readinggives the screw pitch. 3) To determine pitch diameter the lateral movement to the table is given 4) To determine the thread handle, the screen is rotated until a line on the angle of
  • screen rotation is noted. The screen is further rotated until the same line coincides withthe other flank of the threads. The angle of thread on the screen will be difference in twoangular readings. Different types of gradated and engraved screens and corresponding eyepiece are used for measuring different elements.Results:- 1) External diameter = R2 - R1 = -------------- mm. 2) Internal diameter = R2 - R1 = -------------- mm. 3) Pitch of threads = R2 - R1 = --------------- mm. 4) Threads angle = R2 - R1 = --------------- mm.Precaution:- 1) Obtain clean picture of cross line and the cross thread seen through theeyepiece. 2) For angular measurements lines must remain parallel to flank edge tothe tooth.
  • EXPERIMENT NO-5Aim- Measurement of the Straightness and Square ness Using AutocollimatorApparatus- AutocollimatorTheory- Definition of straightness-a plane is to be said straight over a given length. If thevariation or distance of its point from two planes perpendicular to each other and parallelto the generation direction at of the line remain within specified tolerance limits .thereference planes being so chosen that there intersection is parallel to the straight linejoining two points suitably located on the line to be tested and two points being closeends of the length to be measured.Principal of Autocollimator: - it works on the principal that if the light source is placedin the focus of a collimating lens then the light is projected as parallel beam. If this beamis made to strike a plane reflector normal (perpendicular ) to the optical axis then it isreflected back along its own path brought to the same focus. But if reflector is titled through a small angle the parallel beam is reflectorthrough twice that angle and is brought to focus in same plane as a light source but to oneside at a distance x=2 F – Focal length of collimating lensConstruction: - A line diagram of injected reticule autocollimator consists of three partsas micrometer, lighting unit and collimating lens.Working: - when lamp is illuminated then ray from lamp passes through convener, targetreticule and stills on 45 transparent beam splitter. Beam splitter then reflector is placednormal to optical axis which reflects the ray along its own path and an image istransparent beam splitter and the image is seen through eye piece of microscopic onexternal reflector. Now we tilt the plane reflector by a small angel the ray will reflectback but twice the angle and in this condition we couldn’t fine the image on microscope
  • eye piece. Therefore in order to obtain an image operate micrometer microscope till theimage is seen or collected on an external reflector. Stop rotating micrometer, note downthe reading. The reading are directly in angular value that is in minutes 1, 2, 3 and 10 on. Hence the difference in two reading of micrometer gives the value of ‘x’Therefore we can calculate from equation x= 20Where f is focal length of collimating lens. Auto collimator is quite accurate and read unto 0.1 sec and used for distance.Procedure:- (1) Make the distance of 50mm internal on the w/p (2) Set the cross wire so that two cross will coincide. (3) Set the mirror so that the cross wire will be visible (4) Move the reflector on next 50mm mark and adjust it to see reflection of cross wire. (5) Take the reading of reflected crosswire deviated or moved up or down. Measure the distance between two crosswire Result: - The mean deviation of surface is found out to be 0.024 mm upward and downward
  • Conclusion:- Thus from the experiment we conclude that the surface provided wasnot straight.Precaution:-(1) Adjust the reflector accurately to see the reflected crosswire.(2) Illuminate the eyepiece with sufficient light for accuracy(3) Calculate least count of micrometer accurately.
  • EXPERIMENT NO - 6Aim :- Linear Measurement Using Dial Gauge, Slip and Calibration of Dial Gauge.Apparatus :- Dial Gauge, Slip Gauge, Dial Gauge IndicatorTheory :- The different component of dial gauge indicator is shown in fig. It consistof plunger, removable contact pt, stem a transparent glass cover, calibrated dial pointer,bezel camp or bezel locking nut. Revolution counter in order to counter in order to countthe no of revolution of a pointer, dust proof cap etc. It consists of a plunger which slides in bearing and carries a rackwith it. The rack is meshed with pinion (P1) again pinion (P2) and gear (G2) are on samespindle [because of which magnification is taking place]. The gear (G1) is meshed with(P1) again pinion (P2) and gear (G2) are on spindle basically gear (G2) is meshed withpinion (P3) on whose spindle pointer is attached. The pinion (P3) is meshed with gear(G3) on which a light is here spring is attached in order to guide the movement of plungera rack guide is provided and to bring the plunger to its initial position a light coil spring isattached to plunger. Any linear displacement given causes rack to move upward during thisupward movement as rack is meshed with pinion (P1) and gear (G1) rotate by someamount but as the no of teeth on gear (G1) is more compared to that of pinion (P2) whichis meshed with it rotate more time. Let us say if there is 100 teeth on gear G1 and 10teeth on pinion P2 the 1st stage of magnification is 100/10=10 times again. Therefore overall magnification can be calculated, (G1XG2)/ (P2XP3) EG : (100x100/10x10) = 100 In this way dial indicator works you can take diff readings bykeeping standard and object. Then comparison can be made. The magnification is about 250-1000.
  • Dial gauge -Dial gauges divided in two categories, type1 &type2for general engineering purposedepending upon the movement of the plunger. These are manufactured in two grades,grade a and grade b, with total plunger movement or lift of 3,5 and 10mm. Type1 dialgauge has the plunger movement parallel tip the plane of dial and type 2 has the plungermovement perpendicular to the plane of dialIndicator gauge-Dial indicator has been used with several auxiliary devices for a wide variety of lengthmeasurement. Obviously dial indicator can be used for carrying the neededcomplimentary function, resulting in a single tool, it is known as indicator gauge.It must be remembered that indicator gauge are always comparator type measuringinstrument and require the use of a setting gauges for establishing the basic measuringpositionSlip gauge-Slip gauges with three basic forms are commonly found. These are rectangular squarewith center hole, and square without center hole.Rectangular forms is the more widely used because rectangular block are less expensiveto manufacture, and adopt themselves better to application where space is restricted orexcess weight is to be provided.For certain application squarely gauges, through expensive, are preferred. Due to theirlarge surface area, they wear longer and adhere better to each other when touch to highstack.
  • PROCEDURE :-For calibration checking. 1. The slip gauge is used for the purpose of checking the calibration. 2. A known slip gauge is taken and placed on the surface, the indicator gaugewhich has 3.The least count of instrument is calculated 4. The deflection of the pointer is noted and the final reading is obtained 5. For measuring the dimension of a given sample , a known slip gauge ismatched with the given sample ;the comparator is put on the surface without disturbingthe reference setting7. If the sample is greater then reference one, the pointer shows deflection which ismeasured and reading is calculated.OBSERVATION :Slip gauge For linear measurement least count = (0.2/200)=0.001 mm/div

  • EXPERIMENT NO:- 7Aim :- Use Of Optical Flat And Monochromatic LightAppratus :- Optical Flat And Monochromatic Light SourceOptical FlatOptical flats are cylindrical in form with the working surfaces flat and are of two types:Type A-It has only one surface flat. The working surface of this type of flat is indecentlyby an arrow head on the cylindrical surface pointing towards the working surfaces.Type B-It has both the surfaces flat and parallel to each other.Type A are used for testing the flatness of precision measuring surface of flats, slipgauges, measuring tables, etc. Type B are used for testing measuring surfaces ofmicrometers, measuring anvils and similar length measuring devices for testing flatnessand parallelism.These are generally made of either fused quartz or borosilicate glass. This glass is clearand colorless and free from inclusions and defect like bubbles, internal strains andextraneous matter.The cylindrical surface of the optical flat are finished by grinding and the workingsurfaces are finished by lapping and the polishing process. The finishing is done to suchan extent that straight and parallel interference b fringes are produced when the opticalflat is viewed under a monochromatic source of light by placing it in contact withreference flat surface. Their edges are generally beveled to45 degree by a suitablegrinding or polishing process so that the edges are free from any chips. Out measurement of length variation when reference plane of the measurement isestablished and both indicator and object are located in a definite relation to the commonreference plane. These are achieved by means of appropriate gauging set-ups.when dialindicator united with member which serve.
  • PROCEDURE :- 1. Start the optical flat m/c and place w/p on platform whose curvature is to be measured. 2. Now the Optical flat is placed on it and observed the types of fringes appear on the optical flat. 3. To take a current reading applying the finger tip at a center of optical flat and observed the behavior of fringes made on optical flat. 4. By comparing behavior on the fringes with std-one & decided whether the surface is convex concave or flat etc.Result: - Thus we are studying the different types of flat or curvature of surface.PRECAUTION :- 1) Take care while putting optical flat on surface that finished surface is on w/p 2) Handle the optical flat carefully while observing the curvature 3) Apply on the moderate pressure for proper contact
