OUTCOMES

Upon the completion of this course the students will be able to

  • Measure the gear tooth dimensions, angle using sine bar, straightness and flatness,
    thread parameters, temperature using thermocouple, force, displacement, torque and
    vibration.
  • Calibrate the vernier, micrometer and slip gauges and setting up the comparator for the
    inspection.
