“…Šlifavimo abrazyviniais diskais operacijos plačiai taikomos metalui ir kitoms konstrukcinėms medžiagoms apdirbti, kai reikia gauti didelio tikslumo (iki 4-ojo kvaliteto) ir mažo paviršiaus šiurkštumo (iki R a 0,04 µm) detales (Ivanova 2016). Be to, šlifavimo būdu detalės gali būti rupiai apdirbamos, nuvalomi liejimo, kalimo, frezavimo, tekinimo bei suvirinimo siūlių nelygumai, pjaunamos labai kietos medžiagos (virš 60 HRC), galandami įvairūs įrankiai (Silva et al 2017).…”

“…Šlifavimas yra daug sudėtingesnis už tekinimą, gręžimą, frezavimą ir kitus pjovimo būdus. Šlifavimo diskas yra daugiaašmenis pjovimo įrankis, sudarytas iš daugybės rišančiąja medžiaga sujungtų pjovimo elementų, kurie būna netaisyklingos daugiabriaunės formos su aštriomis arba suapvalintomis briaunelėmis (Silva et al 2017). Sukantis diskui, abrazyviniai grūdeliai dideliu greičiu pjauna daugybę smulkių netaisyklingos formos drožlelių.…”

“…It has been shown that the pitch of leaf veins also has a considerable impact on the cooling and nutrient transport effects of the leaves [15,16]. And the structured area of the grinding wheel has an essential in uence on the grinding quality [17,18]. This meat that it was signi cant to study the effect of the micro-grooves pitch of the leaf-vein bionic grinding wheel on the performance of the grinding wheel.…”

In order to enhance the grinding performance of alumina ceramic materials, the surface of the grinding wheels are ablated by laser radiation before grinding, and the three types of leaf-vein bionic grinding wheels with different micro-groove pitches are formed to compare the grinding experiments with normal grinding wheels. The grinding forces and surface roughness were gauged and the morphological characteristics of ground workpiece surfaces were studied. The results showed that with the increase of groove pitch, the normal grinding force was reduced by 9.6-63%, while the tangential grinding force is reduced by 8.3-42%. The groove can promote the flow of coolant, accelerate the heat dissipation and chip removal in the grinding area, reduce the damage of the workpiece and the wear of the grinding wheel, so the vein bionic grinding wheel had more tremendous processing advantages. Among the four kinds of grinding wheels, the leaf-vein bionic grinding wheel with groove pitch equal to 8mm obtained the best grinding effect. The vein-shaped groove had a positive impact on the grinding process.

“…In this way, the process ranges from high material-removal rates to finishing and ultra-precision operations, being the final step in the manufacturing process chain. Silva et al [ 4 ] point out that it is crucial, in this context, to evaluate the comparative performance of grinding wheels, evaluating several aspects connected to product specifications and process sustainability. They propose an evaluation methodology that is able to identify the typical curve of the grinding wheel, analyze the output process variables, and define the sustainability indicators.…”

This paper investigates the grinding process on unreinforced (PA66) and reinforced glass-fiber polyamide 6,6 (PA66 GF30) with Al2O3 and SiC abrasive wheels. Both materials were ground by varying rotations, workpiece infeed speed, depth of cuts for sequential roughing/finishing steps. Dry and liquid coolant conditions were also considered during the grinding process to evaluate the effects on part quality. The surface roughness was used to assess the quality of the final products with several parameter combinations, identifying the induced process trends. The results show that at the end of the finishing step, the surface roughness Rz was lower than 4 μm, attaining the lowest value of 1.34 μm for PA66 specimens. The analysis also suggested the choice of the Al2O3 grinding wheel to reach the lowest Rz values for both materials.
