Abstract
An process for working a material in which a reverse thermal fluid is used as a cutting fluid and, as a result of heat generated during the working process, the fluid increases in temperature above its transition temperature and viscosifies and thickens. In another embodiment, the invention is an article of manufacture of a material which has been worked to increase its temperature and a reverse thermal fluid in intimate thermal contact with the material above the transition temperature of the reverse thermal fluid.
Claims20
A process for working a material comprising:
- a) Providing the material
- b) Providing equipment means to work the material
- c) Providing a reverse thermal fluid at a temperature below its transition temperature
- d) Using the equipment means to work the material so that friction is created, heat is generated and the temperature of the material is increased
- e) Applying the reverse thermal fluid to the material or to the equipment means to work the material, or to both the material and to the equipment means to work the material before or during the process of working so that the temperature of the reverse thermal fluid increases above its transition temperature and its viscosity increases
- in which a visible layer of the reverse thermal fluid with temperature above its transition temperature and with increased viscosity adheres to the material.

An article of manufacture comprising:
- a) A material which is being worked or which has recently been worked so that heat has been generated and
- b) A reverse thermal fluid in intimate thermal contact with the material where the temperature of the reverse thermal fluid is above its transition temperature and is in its higher viscosity range
- in which a visible layer of the reverse thermal fluid with temperature above its transition temperature and with increased viscosity adheres to the material.
