310101f Precision Measurement

Precision Measurement

The process of measuring with a high degree of accuracy and consistency.

Direct Measurement

A technique that involves using a tool such as a rule or protractor to read a measurement directly from the workpiece.

Surface Contact Measurement

A method that provides better accuracy than eye measurement, by measuring the workpiece between two jaws or points like a caliper.

Optical Measurement

Measurement technique utilizing optical magnifying lenses for the highest accuracy.

Steel Rule

A commonly used precision measuring tool that can read fractions of an inch or millimeters, and can be flexible to wrap around curved workpieces.

Measuring Tape

A tool with a true zero end hook that allows for accurate inside and outside measurements.

Hook Rule

A measuring tool that measures from the edge or shoulder of a workpiece and can also measure flanges and circular pieces.

Depth Rule

A measuring tool designed to measure holes and depressions that normal rules cannot access.

Thickness Gauge

Also known as feeler gauges, these tools measure very thin gaps between surfaces.

Vernier Caliper

An accurate measuring device that can measure internal and external dimensions with precision down to thousandths of an inch.

Vernier Scale

A scale that allows for accurate interpolation of measurements, invented by Pierre Vernier.

Micrometer

Precision measuring tool that can measure thickness or diameter with high accuracy, often reading to thousandths of an inch.

Gauge Blocks

Precision ground blocks used in the standardization of lengths in industry.
