Reducing Friction between Chip and Tool
Friction between chip and tool is one of the major challenges faced during machining processes. It causes excessive heat generation, tool wear, and poor surface finish. However, the friction can be reduced by increasing the cutting velocity. The following points explain why:
Increased Temperature
- When cutting velocity is increased, the temperature at the cutting zone also increases.
- The increase in temperature softens the material being machined, making it easier for the tool to cut through.
- This reduces the forces acting on the tool and chip, hence reducing the friction between them.
Reduced Contact Time
- When cutting velocity is increased, the tool spends less time in contact with the workpiece material.
- This reduces the chances of adhesion and built-up edge formation, which contribute to friction between the chip and tool.
Chip Breaking
- At high cutting velocities, chips tend to break into smaller pieces.
- Smaller chips have less contact area with the tool, hence reducing the friction between them.
Conclusion
In conclusion, increasing cutting velocity is an effective way of reducing friction between chip and tool during machining processes. This reduces tool wear, heat generation, and improves surface finish.
