What is a caliper used for in machining?

A caliper is a precision measuring tool commonly used in machining to measure the distance between two opposite sides of an object. This capability is crucial because accurate measurements are essential for ensuring that parts fit together correctly and function as intended in a final product. Calipers can provide internal and external measurements along with depth measurements, making them versatile tools in the machining process.

This measurement ensures high dimensional accuracy across various machining operations, such as turning, milling, and drilling. Quality control checks often involve calipers to verify that machined parts meet the specified tolerances stated in technical drawings and plans. Thus, the primary function of a caliper in machining aligns perfectly with the accurate measurement of distances, affirming its significance in the overall manufacturing and assembly process.
