Finishing operations are one of the most challenging tasks during a manufacturing process, and are responsible for achieving dimensional accuracy of the manufactured parts and the desired surface topography properties. One of the most advanced finishing technologies is grinding. However, typical grinding processes have limitations in the acquired surface topography properties, especially in finishing difficult to cut materials such as Inconel 625. To overcome this limitation, a new type of grinding wheel is proposed. The tool is made up of grains of different sizes, which results in less damage to the work surface and an enhancement in the manufacturing process. In this article, the results of an experimental study of the surface grinding process of Inconel 625 with single-granular and multi-granular wheels are presented. The influence of various input parameters on the roughness parameter (Sa) and surface topography was investigated. Statistical models of the grinding process were developed based on our research. Studies showed that with an increase in the cutting speed, the surface roughness values of the machined samples decreased (Sa = 0.9 μm for a Vc of 33 m/s for a multigranular wheel). Observation of the grinding process showed an unfavorable effect of a low grinding wheel speed on the machined surface. For both conventional and multigranular wheels, the highest value for the Sa parameter was obtained for Vc = 13 m/s. Regarding the surface topography, the observed surfaces did not show defects over large areas in the cases of both wheels. However, a smaller portion of single traces of active abrasive grains was observed in the case of the multi-granular wheel, indicating that this tool performs better finishing operations.

“…This results in lower Sa values (about 1 μm), and for a multi-grain disc it is even below 0.5 μm (due to the reduction in sealing resulting from the disc design). The complementary analysis of grinding parameters in the results obtained makes it possible to look for innovative solutions in other research works [ 39 , 60 , 61 ].…”

As one of the crucial functional units in ultra-precision machines, the hydrostatic guideways have been commonly adopted due to their own superiority. Although the existed analysis approaches can enable researchers to understand the influence of various design parameters on motion accuracy of hydrostatic guideways, the corresponding imperfections remain to be captured easily. In this paper, targeted at avoiding those defectiveness as much as possible, the kinematic theory based quasi-static analysis model with less simplification is developed directly, wherein the profile pattern difference between main and vice guide rails induced by the manual lapping technology is taken into consideration, and the general structure of hydrostatic guideways extracted from Z axis of the ultra-precision grinding machine UPG80 is determined as the research object. Three CASE studies are proposed orderly to verify the correctness and effectiveness of the established analytical model, and the results demonstrate that the variation trends of the theoretically calculated vertical straightness errors are in good accordance with those of the experimentally measured. Furthermore, the fluctuation amplitude deviation between the predicted and the measured motion accuracy does occur in CASE 3, which should be attributed to the accumulated thermal effect revealed via an experimental platform of hydrostatic guideways with similar structure type to the research object. It also is figured out that, the variation of three components of guide rails’ profile errors caused by the thermal accumulation leads to the fluctuation amplitude deviation reflected in CASE 3, and the level of influence can be known as Amplitude component ( E) > Phase component ( φ) Upside wavelength component ( λup) > Downside wavelength component ( λdown). This study can serve as a valuable foundation for improving the motion accuracy of hydrostatic guideways and is also confirmed to be valuable to the peer designers.
