OBJECTIVE To demonstrate the correct method of measuring using an outside micrometer. To become familiar with micrometer. To show the correct choice and use of gauge sets. To identify the common types, length, diameter, grade, and thread pitch of threaded fasteners. 9/12/2018 Exp.3: Micrometers &Feeler, Pitch, Radius and Dial gauges

Micrometers A micrometer is a widely used device in mechanical engineering for precisely measuring thickness of blocks, outer and inner diameters of shafts and depths of slots. Micrometers have several advantages over other types of measuring instruments like the vernier caliper they are easy to use and their readouts are consistent. 9/12/2018 Exp.3: Micrometers &Feeler, Pitch, Radius and Dial gauges

Feeler Gauge A feeler gauge is a simple tool used to measure thicknesses. It is mostly used in engineering to measuring the clearance between two parts.. Taper & Parallel feeler gauge is a feeler gauge of tapered, as opposed to parallel, shape. 9/12/2018 Exp.3: Micrometers &Feeler, Pitch, Radius and Dial gauges

Radius Gauge A radius gauge is a tool used to measure the radius of an object. 9/12/2018 Exp.3: Micrometers &Feeler, Pitch, Radius and Dial gauges

Thread Pitch Gauge It used to quickly determine the pitch of various threads by matching the teeth on the leaves with teeth on the work. 9/12/2018 Exp.3: Micrometers &Feeler, Pitch, Radius and Dial gauges
