TS ISO 3002-1/Amd 1

TS ISO 3002-1/Amd 1. OFFICIAL SCOPE IS UNAVAILABLE. This amendment belongs to the TS ISO 3002-1 series on basic quantities in cutting and grinding, with a focus on the geometry of the active part of cutting tools: general terms, reference systems, tool and working angles, and chip breakers. In general technical terms, this subject provides the shared vocabulary used to describe how a cutting edge is positioned, how angles are referenced, and how chip-control features are identified in machining practice.

Why geometry terms matter in machining

Tool geometry is central to material removal because it influences chip formation, force direction, edge engagement, and the overall behaviour of the cutting zone. Reference systems are the language that makes these angles comparable across tools and drawings, so the same geometric feature can be described consistently by manufacturers, users, and technical documentation. Without that common framework, the same tool could be measured or interpreted in incompatible ways.

Chip breakers are geometric features intended to help control chip shape and chip flow. In practical machining, the distinction between tool angles, working angles, and auxiliary features matters because it affects how a tool performs and how its geometry is communicated. The title also places cutting and grinding together within a broader terminology framework, which is useful for understanding fundamental quantities in manufacturing and metrology.

• This record is an amendment and should be read in relation to the parent standard.
• The subject is the terminology and reference geometry of cutting tools.
• Tool and working angles are core descriptors of cutting behaviour.
• Chip breakers are part of chip-control geometry.
• Consistent terminology reduces ambiguity in technical communication.
