Description: |
| Claim:
In metal cutting operations, it is common practice to throw large quantities of a liquid coolant on the cutting tool to prevent it from reaching excessively high temperatures. However, during the process of flooding the cutting tip of the tool, the chip is also flooded and cooled, increasing its shear strength, and, therefore, making it more difficult to machine and deform than if allowed to retain its friction-generated heat. |
