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. In the grinding process, the friction energy generated by grains and the workpiece in the grinding zone will affect the service life of the grinding wheel. Ultrasonic-vibration-assisted grinding (UVAG) can reduce the friction force and reduce the generation of friction energy during grinding.

Grinding Machine: Parts, Working, Operations, & More [PDF]

A grinding machine is a type of machine used to grind workpieces. It basically uses emery or an abrasive wheel as the cutting tool. The grinding process is truly a chip-producing machining process. The rough surface of the abrasive wheel spreads into small portions of the workpiece as required.In this model, r s represents the radius of grinding wheel, w s shows circular frequency of ultrasonic vibration, w is initial phase of extrasonic radiation, and φ shows the initial phase of ultrasonic vibration. A is ultrasonic amplitude, t represents time, and workpiece feed rate is Vw.. Equations () and show that there are different states of Mechanism and experimental evaluation on surface morphology

Grinding Chatter Detection and Identification Based on

Grinding chatter is a self-induced vibration which is unfavorable to precision machining processes. This paper proposes a forecasting method for grinding state identification based on bivarition empirical mode decomposition (BEMD) and least squares support vector machine (LSSVM), which allows the monitoring of grinding The machine vibration spectra shown in Figs. Figs.7 7 10 indicate that the major vibration peaks are in the middle frequency range (20–250 Hz) and they are mostly integer multiples of the speed-related frequency (f Speed) These relationships suggest that the machine vibration in a normal situation is likely to result primarily from mechanical Vibration characteristics of golf club heads in their handheld grinding
