Study Notes
Cutting Tool Characteristics
- For longer use, tools with higher toughness are preferred, as they can withstand impacts and vibrations without breaking.
Rake Face Phenomenon
- On the top rake face of a cutting tool, chip flow occurs, which affects the tool's performance and lifespan.
Brittle Fracture Causes
- The main cause of brittle fracture in cutting tools is the presence of tensile stresses, which can lead to sudden and catastrophic tool failure.
Flank Wear Location
- Flank wear occurs on the clearance face of a cutting tool, which is the surface adjacent to the machined surface.
Temperature Failure Causes
- The primary cause of temperature failure in cutting tools is high temperature gradients, which can lead to thermal softening and reduced tool performance.
