“…If there is a difference and thus tilt between the ideally flat grinding wheel surface and the longitudinal axis of the measuring system, a compensation line is calculated and the measured values corrected. The use of a 4 th degree polynomial as an approximation of the wheel profile turned out to be sufficiently accurate during measurements and in relation to previously published wear forms [1,3,5,6,10]. By measuring at different angular positions on the grinding wheel, wear characteristics dependent on the circumference can be determined.…”

“…Due to the process typical kinematics, the workpieces cover different path lengths in the individual areas of the grinding wheels, and the cutting speed depends on the current workpiece location. Using the kinematic models developed by Simpfendörfer [10], Ardelt [3,16,17], Uhlmann et al [5][6][7] and List [1], these values can be calculated for the selected process parameters. Here, during grinding the cutting speed difference in the inner and outer area of the grinding wheels is comparatively higher with v c,diff = v c,max − v c,min = 1.44 m/s compared to the difference in the dressing experiments v cd,diff = 0.27 to 0.70 m/s.…”

“…The inhomogeneous cutting speed v c and contact lengths between the workpieces and the different grinding wheel areas during grinding lead to a significant deviation in the investigated topography parameters. On the tool wear model proposed by Uhlmann et al [6] and List [1], the workpieces cover more than twice as much path length on the outside as on the inside of the grinding wheels in the performed grinding process. The grinding wheel profiles determined after grinding depends on the calculated path length covered by the workpieces in the areas of the grinding wheels (Fig.…”

In grinding, the design of the dressing process is an essential part of work preparation and restoration of the grinding wheel’s profile and cutting ability. In contrast to most grinding processes, the choice of dressing parameters in double face grinding with planetary kinematics has so far only been experience-based. As a consequence, the dressing process causes a higher degree of tool wear than the machining of the workpieces. A focused design of the dressing process based on a scientific data could help to improve the ecological and the economic efficiency by reducing tool wear and the amount of dressing tools used. In this paper, methods for determining the wear condition and the result of the dressing process, including macro- and microscopic characteristic are presented. This includes a correlation analysis between parameters of wear characteristics and workpiece surface quality. Furthermore, technological investigations are carried out in order to systematically limit the main influencing factors on the dressing process. As a result, the parameters dresser grain size dgd, rotational speed ratio nld and the machined dresser height ∆hd are identified as significant for dressing. The knowledge about their principal influence on the dressing result could provide the basis for further research.

Laser-induced deterioration was proposed for the wet grinding of zirconium oxide (ZrO 2) ceramic used in the dental, semiconductor and automotive industries. The mechanisms for laser induced deterioration and wet grinding of the deterioration layer were theoretically analysed, and the four key processing parameters that determine the micro-topography and distribution of the laser-induced crater were proposed, including the laser power density I p , the defocus distance z, the laser spot overlap ratio U s and the laser scanning track line overlap ratio U l. Further, the forming mechanism of the single pulse-induced crater under different laser power densities, the defocus distance, and the interaction mechanisms between adjacent spots along the longitudinal and transverse directions were investigated. The optimal values of the key processing parameters were identified. To further evaluate the effect of laser-induced deterioration objectively, a comparative experiment was conducted under laser-induced deterioration wet grinding (LIDWG) and conventional grinding (CG) conditions. It was found that the procedure of laser-induced deterioration had a strong influence on the grinding results. The normal and tangential grinding forces for LIDWG condition were lower than for CG condition, with a maximum reduction of 59.2 % (62.9 %).
