Assessment of Microhardness Profile in Grinding Using ...

An experimental investigation was carried out to study the effect of variation in Barkhausen noise (BN) analysis parameters (magnetizing voltage and excitation frequency) for assessment of microhardness profile upon surface grinding. A varying amount of surface damage was induced in the ground samples by changing the downfeed during grinding.

Simulation of Levels of Noise Generated by Local Grinding ...

Levels of noise generated from grinding machines were measured. Noise levels as high as 116dB was obtained. These levels of noise can be stressful that can result to fatigue. It is capable of causing temporary and permanent deaf. Noise spectra generated from grinding machines are mixture of low and high frequencies. Low and high frequencies noise can have negative effects on memory.

Tinnitus: Characteristics, Causes, Mechanisms, and Treatments

Natural course. Noise-induced tinnitus can be acute or chronic. Acute tinnitus can last from a few minutes to a few weeks after noise exposure. 24 In some cases, tinnitus has a gradual onset and several years can pass before an intermittent, low-intensity tinnitus becomes bothersome. 25 Spontaneous remission by natural habituation is experienced by more than three-quarters of sufferers.

Experimental study of wheel wear in electrolytic in ...

Profile accuracy of components ground with ultra-precision machine tools is primarily dependent on wheel wear. Quantitative analysis of wheel wear is therefore an important aspect for precision grinding with electrolytic in-process dressing (ELID). In this paper, wheel wear is measured from ELID grinding experiments with different dressing and machining parameters. The grinding …
