TS 6920

TS 6920 is a terminology standard that defines the terms used for force, energy and power in cutting and grinding. Standards of this kind create a common engineering language for machining processes, helping users describe measurements, calculations and process behaviour with the same conceptual basis.

Why these quantities matter in machining

In general technical use, force describes the interaction between the workpiece and the tool or grinding wheel, energy expresses the work associated with that interaction, and power shows how quickly that work is delivered over time. In cutting and grinding, these quantities give complementary views of process load, efficiency and machine behaviour. As a terminology standard, TS 6920 clarifies how these concepts are to be understood in this field, reducing ambiguity when the same words are used across different documents or engineering contexts.

Document boundaries and context

The standard covers the definitions of force, energy and power terms used specifically in cutting and grinding; it does not claim to regulate all general mechanics terminology. Identified as equivalent to ISO 3002-4:1984, it aligns the vocabulary with internationally recognised machining terminology and supports consistent use in machine engineering, production technology and technical documentation related to machine tools.

• Provides a shared definition set for force, energy and power.
• Supports consistent technical communication in cutting and grinding.
• Helps standardise machining documentation and terminology.
• References equivalence with international machining vocabulary.
