A model for simulating vibration responses of grinding

The objective of this study was to develop a vibration model of a grinding machine-workpiece-hand-arm system. A lumped-parameter model structure of the system was proposed, and its major parameters were determined using the mechanical impedance measured at the grinding point of a typical workpiece (golf club head) held by two hands and referenced to the vibration transmissibility spectra measured

ANALYSIS AND CONTROL OF VIBRATION IN GRINDING MACHINES

Vibration in grinding machine is hard to measure. It is witnessed from the formation of waviness on the work piece and grinding wheel. The major causes of vibration in grinding machine are misalignment and unbalancing. These unwanted vibrations will reduce the life of both machine and tool, resulting in loss of production. Vibration measurement is done by different approaches.

GRINDER RISK ASSESSMENT IN FABRICATION UNIT

a grinding machine, hand grinder, or hand grinders. This grinding process has imposed a considerable risk as seen in the company's accident report in 2017 where the most common occupational accident was eye injury experienced by a grinder operator in performing the grinding process. Occupational accidents ever caused disability to a grinding operator in 2014. As a result, he could

Analysis of Residual Stress Induced by Hand Grinding

Grinding cup wheel is often used in the case of hand grinding which allows an important material removal rate but with secondary concern of surface integrity. Integrity is strongly affected by the process and consequently influences the surface behaviour in terms of resistivity to stress corrosion and crack initiation. This operation is difficult to master in terms of results on the surface
