Calipers[edit]
Calipers are a device used to measure the distance between two opposite sides of an object. They are commonly used in various fields such as mechanical engineering, metalworking, forestry, woodworking, science, and medicine. Calipers can be as simple as a compass with inward or outward-facing points, but they can also be sophisticated devices with digital displays.
Types of Calipers[edit]
There are several types of calipers, each designed for specific measurement tasks.
Inside Calipers[edit]
Inside calipers are used to measure the internal size of an object. They consist of two legs that are adjusted to fit inside the object being measured. The measurement is then read by comparing the calipers to a ruler or a measuring tape.
Outside Calipers[edit]
Outside calipers are used to measure the external size of an object. They work similarly to inside calipers but are designed to measure the outside dimensions. The legs of the calipers are placed around the object, and the measurement is taken by comparing the calipers to a standard measuring device.
Divider Calipers[edit]
Divider calipers are used for marking out workpieces. They consist of two sharp points and are used to scribe lines on surfaces or to transfer measurements from one object to another.
Oddleg Calipers[edit]
Oddleg calipers, also known as hermaphrodite calipers, are used to scribe a line at a set distance from the edge of a workpiece. They have one straight leg and one bent leg, allowing them to be used for marking parallel lines.
Vernier Calipers[edit]
Vernier calipers are a more advanced type of caliper that includes a vernier scale for increased precision. They can measure internal and external dimensions as well as depths. The vernier scale allows for measurements to be read to a fraction of a millimeter or inch.
History[edit]
The history of calipers dates back to ancient times. The earliest calipers were simple tools used by craftsmen and artisans. Over time, calipers have evolved into more precise instruments with the development of vernier scales and digital displays. The use of calipers has been documented in various cultures, including ancient China and Rome.
Applications[edit]
Calipers are used in a wide range of applications. In engineering and metalworking, they are essential for ensuring that parts fit together correctly. In woodworking, calipers are used to measure the thickness of materials and the dimensions of joints. In medicine, calipers are used to measure body parts and to assist in surgical procedures.
