“…1. Pojemności cieplne czynników stosowanych w obróbce z minimalnym wydatkiem olejowym MQL [30] W wielu pracach [14,[31][32][33][34][35][36][37][38][39][40][41][42] autorzy wykazują znaczny potencjał ograniczenia wydatku PCS przy zastosowaniu metody MQL w procesach szlifowania. Prowadzone są rów-nież prace w zakresie zastąpienia oleju innymi środkami smarnymi o mniejszej szkodliwości dla środowiska, takimi jak np.…”

“…Also, the costs related to workpiece cleaning are minimized, and the operation of cutting is more visible to the operator, since cutting fluid does not cover the workpiece 18 . However, one of the disadvantages is that MQL does not promote cooling as efficient as when using flood coolant 20 . This drawback, along with the higher heat transferred to the workpiece during machining, compared to the use of defined geometry tools (since abrasive grains have a negative rake angle, increasing friction at the interface and deformation of the chip), leave traditional MQL insufficient to abrasive processes, when cooling is necessary.…”

“…Microhardness measurements corroborate with this result, since a value of 849.1 HK was obtained, much higher than the reference values. During grinding of hardened steels, surface burns promote hardness increase, which is caused by quenching, consequence of reaustenitizing followed by formation of non-annealed martensite 20,24 . White burns are very deleterious to the workpiece integrity, since the hardened surface becomes extremely brittle, and high tensile residual stresses are present, which can cause crack nucleation and growth, reducing considerably wear and fatigue resistances 20 .…”

“…Frank et al pointed out that hydrodynamic lift force is remarkably high in the overall grinding resistance, and suggested that a grooved wheel was effective to release the pressure generation [21][22]. Furutani et al suggested a new in-process method to monitor not only the topographical grinding wheel conditions such as loading or dulling but also the real displacement of wheel spindle caused by the overall grinding resistance [23][24]. Moreover, some research groups tried new polishing techniques by adopting NC control of polishing wheel, which provides not only the fluid velocity field but also high speed particle motion generated by both fluid speed and centrifugal force in the near contact zone [25][26][27][28].…”
