Study Notes
Cutting Tools
- A multi-point tool has more than one cutting edge.
Fracture Failure
- The primary cause of fracture failure in cutting tools is brittle fracture.
Energy in Machining
- Approximately 98% of the energy in machining is converted into heat.
Single-Point Tools
- The purpose of the rounded nose radius in single-point tools is to strengthen the tool and reduce the risk of chipping or cracking.
Tool Failure
- Excessively high cutting temperature can cause tool failure primarily through thermal softening.
