“…Their results further demonstrated that wet grinding when using a CBN or a diamond wheel tended to produce convex warp. Alves et al (2009) found larger forces and surface roughness after the spark-out operation when using the minimum quantity lubrication method than when using the conventional cooling method and with a Webster nozzle. The amount of cutting fluids can thus affect the surface roughness and possibly the flatness of a ground surface.…”

Spark-out produces parts with high flatness and smooth surfaces in grinding. Elastic deformation on wheels and workpieces diminishes during spark-out, and this increases dimensional accuracy. Despite its potential for high-quality productions, spark-out is time-consuming. While examining the thermal distortion on ground surface in spark-out, this study develops a strategy to achieve high flatness on ground surfaces. A numerical model is developed to analyze the surface deformations in dry grinding. Additionally, exactly how set depth of cut (SDOC), wheel properties and cutting fluid affects surface profile during spark-out is examined by experiments. Results of the study demonstrate that concave distortion of the profiles is reduced during spark-out with dry grinding, and the profiles turn convex with wet grinding of steel with a white alumina wheel. Optimum flatness is generally achieved, when a smaller SDOC and cutting fluid are used in the experiments.

This paper provides a state-of-the-art review on the investigations into the residual stresses in metallic structural materials generated by grinding. The materials covered include steels, titanium alloys, and nickel-based superalloys. The formation mechanisms of the residual stresses and their impacts are specifically discussed. Some major influential factors on the residual stresses formation in grinding, such as grinding wheel characteristics, dressing techniques, grinding parameters, cooling conditions, and properties of workpiece materials, are analyzed in detail. These include experimental measurement, modeling, simulation, knowledge-based monitoring, and fuzzy analysis. Finally, the paper highlights some important aspects of grinding-induced residual stresses for further investigation.

“…Due to the intrinsic nature of grinding, being an intense heat generation process, large amounts of cutting fluid are used, aiming to reduce the high temperatures at the contact zone (Alves et al, 2009). Cutting fluid composition as well as nozzle design and placement are parameters which greatly influence productivity, workpiece final quality and wheel wear (Brinksmeier et al, 1999).…”
