“…The high pressure draft functions in cooling and chip removal. Lubricants attach onto the finished surface of a workpiece, forming a layer of protective film and serving as lubrication (Brinksmeier et al, 2010;Wegener et al, 2011). This technology integrates the advantages of flood cooling grinding and dry grinding, presenting lubrication effects similar to those of traditional flood cooling grinding (Oliveira et al, 2009;Hadad and Sadeghi, 2012;Tawakoli et al, 2010;Kalita et al, 2012a).…”

Abstract:The heat-transfer model of a surface grinding temperature field with a nanoparticle jet flow of minimum quantity lubrication (MQL), as well as the proportionality coefficient model of the energy input workpiece, was established. Numerical simulation of the surface grinding temperature field of a nano-ZrO 2 dental ceramic workpiece material was conducted. With increased cut depth, the peak values of grinding temperature rocketed. With increased workpiece feed speed, grinding temperature on the finished surface decreased. With increased wheel peripheral speed, a high amount of heat energy accumulated on the surface because of the low heat-transfer coefficient of the ceramic material, and a large temperature gradient appeared in the temperature distribution layer. Under the same cooling and lubrication conditions, grinding temperature insignificantly changed along the direction of grinding width. Conversely, under different cooling conditions, the temperature variation was significant. MQL grinding conditions with additive nanoparticles significantly affected the weakening of temperature effect on the grinding zone.Keywords: grinding; temperature field; nano-ZrO 2 dental ceramics; nanoparticle jet; minimum quantity lubrication; MQL.Reference to this paper should be made as follows: Wang, S., Li, C., Jia, D.

“…The metallic structure must be completely released from the substrate after electroplating process. Various techniques are currently used, for example, a sacrificial layer removal using a chemical etching or laser release [14][15][16], an abrasive removal using a grinding or polishing [17][18], and a removable printing mold [19]. However, these techniques are sometimes complex, destructive and expensive.…”

Abstract.This study aims to demonstrate a simple fabrication technique of freestanding electroplated metallic microstructures by modifying a substrate roughness. The proposed technique utilizes counter effects between two forces, i.e. an intrinsic force causing shrinkage in an electroplated metallic microstructure, and an adhesive force adhering a metallic microstructure to a substrate. With the modification of substrate roughness until the adhesive force becomes weaker than the induced intrinsic force, electroplated metallic microstructures would spontaneously release from the substrate after the electroplating process. Three parameters, i.e. substrate roughness, electroplated square structure's area and electroplated rectangular structure's width-to-length ratio, were experimentally studied. The results showed that the electroplated structure with a smaller size and smaller width-to-length ratio was more easily detached from the substrate for a given substrate roughness. In addition, for the same electroplated structure, a substrate with less roughness allowed a detachment of electroplated microstructure more easily.
