- Cutting speed and feed
- Cutting fluid model and correct use
- Knife cutting method
- Hob clamping
- Maximum wear standard
- Wear standards
- The maximum allowable tool wear shall be formulated, and the tool wear shall be timely grinded after reaching the standard. The recommended values are as follows (for reference only):
- The allowable wear of hard alloy cutting tools is 0.10mm, and 0.15mm is also commonly used in practical applications
- The typical wear amount of powder metallurgy high-speed steel is 0.2mm
- The typical wear amount of traditional high-speed steel is 0.3-0.4mm
- Signs of excessive wear and tear
- The power of the machine tool increases or sharply decreases
- Increased machine tool vibration
- Increased noise during cutting
- Excessive heat is generated, resulting in an increase in the temperature of the workpiece and tool
- Deterioration of workpiece surface roughness
- Workpiece size out of tolerance
- Burrs increase on the cutting surface of the tool along the workpiece
- Measured tool wear with magnifying glass exceeds the standard
- The cutting tool has broken, and there is a feeling of uneven scraping when touching the cutting edge
