TS ISO 3002-3

TS ISO 3002-3 is a terminology standard that explains the basic geometric and kinematic quantities used in cutting and grinding processes. This part organizes the concepts that describe tool–workpiece motion, together with terms such as feed, cutting edge, engagement, cut, pass, and related dimensions. Its purpose is to support a common technical language so these quantities are understood consistently in machining and manufacturing contexts.

Geometry, motion, and material removal

The standard focuses on the fundamental relationships that shape a cutting operation. In general technical terms, geometric quantities describe the form and orientation of the cutting action, while kinematic quantities describe the motion that produces material removal. The cutting edge is the active zone that interacts with the workpiece, and feed describes the controlled advance of the tool or workpiece during machining. By including grinding as well as cutting, the vocabulary covers both conventional chip-forming operations and abrasive material-removal processes under one conceptual framework.

Why the terminology matters

• Provides shared terminology for cutting and grinding.
• Brings together geometric and kinematic quantities in one vocabulary.
• Clarifies core machining terms used in manufacturing engineering.
• Includes equivalent terms in English, French, Russian, German, Italian, and Dutch.
• Names concepts such as material removal rate that are important in process understanding.

This part is intended for general machining use; it is not itself a machine specification or a step-by-step manufacturing method. Its value lies in defining the language of cutting science, so design, process planning, education, and technical communication can use the same terms with greater precision.

TS ISO 3002-3 represents the third part of the ISO 3002 family and provides the core vocabulary for describing geometry and motion in cutting. It is especially useful wherever teams need a clear distinction between form, movement, and the removal of material in machining operations.
