| Abstract [eng] |
This work determines and compares the allowable torque and the maximum torque for tightening the bolt in Friction Drilling process applied for different thin walled materials. Five different thin walled materials were analysed, i.e. S235JR Steel, DC06 Steel, Aluminium alloy, Copper and Titanium thin walled plates, all with a thickness not greater than 1.5mm. since there are no such standard tightening torque to be applied for the bolt in friction Drilling process, the mechanical tests we performed allowed to determine the torque which is to be applied on the bolt for tightening in Friction Drilling process and the same is analysed according to their mechanical properties and also nut factor is also determined. Our experiment is concentrated only M 8.8 bolt and the thin walled material not more than 1.5mm, so its recommended to do more experiments in this field to determine the standards for different bolt dimensions in different thin walled materials which are used in manufacturing sector. |
