Tool-In-Hand system for tool designation
What is Tool-In-Hand system for tool designation? It basically refers to the identification of few useful salient features just by observing the cutting tool in bare eyes. Various features displayed in Tool-In-Hand system for turning tool, drill and milling cutter are also provided here. Read details…
Tool signature – ASA system, ORS system, NRS system
What is meant by tool signature? Various systems for specifying tool signatures are American Standards Association (ASA) system, Orthogonal Rake System (ORS) and Normal Rake System (NRS). Tool signatures in all three systems and corresponding examples are provided here. Read details…

Difference between ORS system and NRS system
Similarities and differences between ORS system and NRS system of tool designation are presented here in table form. Orthogonal Rake System (ORS) uses three mutually perpendicular planes; while planes are not mutually perpendicular in Normal Rake System (NRS). When inclination angle is zero, ORS and NRS become same. Read details…
When ORS system and NRS system will be same?
In which condition ORS system will be same with NRS system? When inclination angle (λ) of a single point cutting tool will be zero, then Orthogonal Rake System (ORS) will be same with Normal Rake System (NRS). Such condition is also illustrated with the help of schematic diagram. Read details…
Comparison among ASA, ORS and NRS systems
Comparison among ASA, ORS and NRS systems of tool designation is discussed here on the basis of three planes used for references, tool signature, displaying nose radius, features of auxiliary flank surface, and other advantages and disadvantages among themselves. Read details…
