Abstract:

This research article deals with the development of strain gauge dynamometer. A dynamometer is a machine used to measure torque and rotational speed (rpm) from which power produced by an engine, motor, pump or other rotating prime mover can be calculated in order to put the analysis of the metal cutting operation on a qualitative basis, certain observations must be made before, during and after a cut. A strain gauge is a device used to measure the strain of an object & the cutting force measurement is performed by the tool is not much costly and can machine materials with some limited criteria. This setup was developed for to measure cutting forces in machining operation. The cutting force cannot be detected or quantified directly but their effect can be sensed using Transducer. A force which can neither be seen nor be gripped, but can be detected and also quantified respectively by its effect and the amount of those effects like elastic deflection, deformation, pressure, strain etc. These effects, called signals, often need proper conditioning for easy, accurate and reliable detection and measurement. This setup is also increase efficiency and accuracy of force measurement by tool deflection in less time without sacrificing accuracy of the product. This strain gauge was designed to measure 200 kg cutting force and feed force as well. The operating parameters were depth of cut, feed per revolution and cutting speed.
