Nanocutting Fluids in CNC Machining Processes

The manufacturing process involves adding value to low-value raw materials and transforming them into high-quality, high-value products that meet customer needs in terms of shape, size, accuracy, and surface finish. To ensure successful manufacturing, the materials and techniques used must be technically feasible, economically viable, and environmentally sustainable. Advancements in manufacturing technology are constantly being made to enhance productivity, improve product quality, and incorporate new materials.

Machining refers to a broad range of technologies and techniques used to remove excess material from a workpiece in the form of chips to shape it into a desired design. During the machining process, the workpiece is subjected to shearing, bending, and compression forces from the cutting tool, resulting in high temperatures and complex mechanical and thermal stresses in the cutting zone. Despite recent advancements, the machining process remains incompletely understood due to its highly nonlinear nature and the intricate coupling between mechanical, thermal, frictional, and vibrational fields.

Cutting fluids play a vital role in machining processes as they provide lubrication, cooling, chip evacuation, and protection against tool wear. There are various types of cutting fluids, and their application depends on the machining operation and the specific requirements.

Nanofluids are suspension of nanoparticles which form a stable colloid and constitute a quasi-single- phase media. Nature of these fluids have strong dependence on the properties of base fluid and nanoparticles, which are influenced by the fabrication technique of nanofluid
