Effects of lubricooling conditions on machining forces and surface roughness in radial grooving

Radial grooving is a machining process usually applied to generate grooves for thread relief, O-ring positioning, or even cutting-off operations. Due the high forces and difficult chip removal, radial considered critical process, cutting fluids are cooling, lubricating, assistance on removal. Compressed air (AIR) minimum quantity lubrication (MQL) lubri-cooling methods studied as environmentally-friendly alternatives conventional flood (WET) applications of fluids. Although already years in several processes, research associated with using alternative techniques incipient. This work presents comparative analysis these (WET, MQL, AIR) their effects. In each case, factorial design experiments was used evaluate influence conditions, speed, feed rate over force, surface roughness. Results indicate that both AIR MQL may be suitable substitutes traditional WET when active force components finish considered. Besides, smaller were obtained grooving, followed by machining.
