Grinding is one of the effective manufacturing processes with which to produce highly accurate parts an ultra-fine surface finish. The tool used remove materials in grinding called wheel. Abrasive grains made extremely hard (alumina, silica, cubic boron nitride, and diamond) having a definite grit size but random shape are bonded on circumferential fabrication process controlled so that wheel e...

distribution of water vapor in the atmosphere of the room poultry houses is usually an effective and economical solution to reduce heat stress of the chickens. experimental studies were conducted in a small saloon located in the farm machinery department of shiraz university. the rotary cup fogging system consisted of a cup which was derived by dc motor. rotational speed of the cup caused the w...

Connecting parallel rail tracks, scissors crossovers typically consist of four turnouts and a central diamond crossing, while flange-way gaps provide wheel flange clearance at the points of rail intersection. Guardrails, supported through base-plates, provide wheel guidance in the area of the gap. In the Athens Metro, within less than a year in operation, fracturing of a vast number of guardrai...

In this work, machining test was carried out in various machining conditions using ultrasonic vibration capable CNC machine. For work material, alumina ceramic (Al2O3) was used while for tool material diamond electroplated grinding wheel was used. To evaluate ultrasonic vibration effect, grinding test was performed with and without ultrasonic vibration in same machining condition. In ultrasonic...
