2018-9-1 The grinding test was performed at the Saint-Gobain Higgins Grinding Technology Center near Boston, Massachusetts. The test machine was an Elb creep-feed/surface grinder. The operation was slot grinding using an 8-inch-diameter, ½-inch-wide conventional
Dynamic Model and Modal Testing for Vibration Analysis of Robotic Grinding Process with a 6DOF Flexible-joint Manipulator Farzad Rafieian and Zhaoheng Liu Bruce Hazel
2020-10-13 Specifically, this research records the vibrations on the grinding wheel and decomposes them using a Fast Fourier Transform (FFT). The vibration patterns at the grinding wheel mesh frequency are studied using two design variables that characterize the tool, a) grinding wheel diameter (d) and b) location along the grinding wheel width (y).
2000-11-1 The grinding machine spindle is one such system where vibration causes major problems in the grinding process as the grinding wheel depth of cut is so small that even the slightest amplitude of vibration can have dramatically damaging effects on surface finish, wheel wear, and form-holding.
According to Peter Zelinski with Modern Machine Shop Online: “In a production-grinding operation, waviness on the part surface is a potential clue that the machine or process has developed a vibration problem. The effect might be seen in inspection, or if there is a lapping or polishing step, more time might be spent during that

Vibration testing showed that the natural frequency of the grinding wheel spindle was being excited by the process. A vibration absorber, or damper, was designed and fitted to the free end of the grinding spindle. The amplitude of vibration was therefore reduced, and workpiece roundness appreciably improved. The five-point lobing was eliminated. 1.
2021-9-2 equipped with an aluminum test wheel of the same size as the grinder is designed for. The test wheels have a pre-defined unbalance given in the standard. The size of the test wheel in this particular case is Ø125 mm (5”). The grinder is operated at its rated air pressure (6.3 bars). The applied feed force is related to

2019-10-4 Laizhou Lyric Testing Equipment Co., Ltd. is a professional company producing and supplying metallographic specimen preparing machines, such as grinding & polishing machine, cut off machine, mounting press, metal and non-metal materials hardness testers, impact testing machines, universal testing machines, torsion testing machines
These vibrations are transmitted to the grinding wheel spindle via the workpiece spindle bearing system. With a long duration of the workpiece speed oscillation, the spark-out time without forced vibrations is short. The effect of grinding with a long duration of the workpiece speed oscillation t w
2009-1-27 grinding wheel, when grinding gears [4]. The diamond grains on the dressing wheel causes undulations on the grinding wheel surface and when grinding the gear, also the gear flank surface will have undulations (waviness). These undulations typically have wavelengths of about 0.5 mm and amplitudes of approximately 4μm.
