Cutting tool geometry is described and designated in several systems.
- Tool-in-hand system.
- Machine reference systems (ASA).
- Tool reference system
- Orthogonal rake systems (ORS).
- Normal rake systems (NRS).
- Work reference system.
Tool signatures have 7 elements in both ASA and ORS systems.
American Standards System (ASA):
Back rake angle (αb) - side rake angle (αs) - end relief angle (γe) - side relief angle (γs) - end cutting edge angle (Ce) - side cutting edge angle (Cs) - Nose radius (r).
Orthogonal Rake System (ORS):
i (inclination angle) - αn (Normal rake angle) - Side relief angle - end relief angle, end cutting edge angle - approach angle - nose radius (r).
∴ in both systems, the nose radius comes at last.
