A strain gauge is a device which is used to measure strain (deformation) on an object subjected to forces. Strain can be measured using various types of devices classified depending upon their principle of operation. Some of them are as follows: 1. Mechanical type, 2. Optical type 3. Pneumatic type 4. Electrical type

Ultrasonic Machining is a mechanical type of non-traditional machining process. It is employed to machine hard and/or brittle materials (both electrically conductive and non-conductive) having hardness usually greater than 40RC (Hardness on Rockwell scale-C). It uses a shaped tool, high frequency mechanical motion and slurry.
