[Material] Basic Series on Geometric Tolerances 11 - Contour Tolerance - (Free Download)
"What is 'contour degree'?" This is a document that also mentions usage examples and measurement methods!
When performing turning or milling operations, the workpiece may retain traces of the cutting tool, and due to the effects of distortion or deflection during processing, there may be some deviation from the ideal shape. Geometric tolerances are used to indicate how much deviation from the ideal shape is acceptable. By understanding geometric tolerances, one can discern the designer's intentions behind the drawings. This also clarifies how to proceed with processing and inspection based on specific references. This document explains a type of geometric tolerance known as "contour tolerance." It discusses both "line contour tolerance" and "surface contour tolerance," as well as how to differentiate between the two.
