The various test performed on the alignment tests on milling machine are, Cutter spindle axial slip or float. Eccentricity of external diameter. True running of internal taper. Surface parallel with longitudinal...
The following alignment tests are carried on lathe. Levelling of the machine. True running of location cylinder of main spindle. Axial slip of main spindle and true running of shoulder face of spindle nose. True running of...
Michelson Interferometer Construction: It consists of a monochromatic light source, a beam splitter and two mirrors. The basic principle involved in Michelson interferometer is constructive and destructive interference when one...
Laser interferometer uses A.C laser as the light source and thus it enables the measurements to be made over longer distance. Laser represents a source of intensively monochromatic optical energy, which can be collimated into a...
Laser stands for “Light Amplification by Stimulated Emission of Radiation”. Laser instruments are devices to produce powerful, monochromatic collimated beam of light in which the waves are coherent. The development of...
Measurement of roundness is defined as a condition of a surface of revolution. All points of the surface are intersected by any plane perpendicular to a common axis in case of cylinder and come. Devices Used for Measurement of...
Definition of Straightness of a Line in Two Planes A line is said to be straight over a given length, if the variation of the distance of its from two planes perpendicular to each other and parallel to the general direction of...
The methods used for measuring the surface finish are classified into Inspection by comparison Direct Instrument Measurements Inspection by comparison methods In these methods of measuring, the surface texture is assessed by...
To find out the accuracy of a screw thread, it will be necessary to measure the following: Major diameter Minor diameter Effective or Pitch diameter Pitch Thread angle and form Measurement of major diameter The instruments...
