Advances and Trends in Non-Conventional, Abrasive and Precision Machining

For further reductions in the temperature of the workpiece due to its interaction with the tool and the subsequent deformations, the machining cell may make an automatic selection of the grain trajectory shape, with specified value of the curvature radii of the abrasive grain trajectories, according to the wall thickness of the honed workpiece. Parameters such as volumetric material removal rate, the dimensional accuracy of cutting and surface roughness are considered, in an experimental work that was carried out with the Box–Behnken design scheme and analyzed through the response surface methodology analysis of variance (ANOVA) tests. Through analysis of variance (ANOVA), conclusions were drawn about the influence of machining conditions on the EDM performance, with consideration of the material removal rate, the surface roughness, the average white layer thickness and the heat-affected zone micro-hardness. The obtained results indicated significantly better roughness and waviness values of the AISI 304 steel surface in terms of its size, periodicity, and regularity; the turning process of AISI 304 shafts with low rigidity helps to achieve a better-quality texture and has a positive effect on the general properties of a workpiece.
