The purpose of this study was to measure the change of coefficient of restitution of golf ball accordance to ball temperature and ball speed. Ball temperature was in the range of 0℃, 20℃ and 40℃, impact speeds of ball toward to 400 pound fixed square steel plate were 70, 85, 100, 115, 130 and 145mph. The data of coefficient of restitution (COR) of golf ball were measured by dividing the out-bound ball speed by inbound ball speed. In oblique impact, the COR applies only to those components of velocity along the line of impact or normal to the plane of impact. One particular type of COR test device that is commonly used in the golf ball industry is the ADC COR machine developed by Automated Design Corporation. The 5 brands and 2, 3, 4 piece balls (total 75 balls) were selected and they were fired the burst of 1,350 rounds. to the steel plate of ADC COR machine.
