There are a variety of tools that are used in mechanical engineering. The engineers use it for testing, assessing machinery, building, and much more. These are 3D printers, digital force gauge, ohmmeter, flow meter, graphing calculator, vibration isolator, calipers, screwdrivers, cold forming press, semiconductor process systems. In addition to this, one uses construction software, CAD software (SolidWorks, CATIA, Fusion360), CAM software, FEA software (ANSYS, etc.).
