Title: Application of Refrigeration Cycle in Machining difficult-to-cut Materials

The machining industry has long faced challenges in dissipating heat from the cutting zone to produce high-quality products with precise accuracy and desired surface finish. Traditional methods often rely on hazardous coolants that pose risks to the environment and operator health. Recently, refrigeration systems have gained attention as an alternative to improve machining performance without cutting fluids.

Most studies focus on cooling the tool holder or cutting tool, but this research explores a novel approach by integrating a refrigeration cycle into a cooling bed to chill the workpiece directly. The study investigates the impact of this method on machining AISI 304 stainless steel (SS) and mild steel (MS) under specific conditions, comparing results with dry machining.

The findings reveal that refrigeration cooling improves surface roughness, tool life, and overall performance compared to dry cutting. This innovative approach offers a sustainable alternative to traditional coolant methods, addressing environmental and health concerns associated with conventional machining practices.
