Popis:	Ultrasonic vibration has shown capability of reducing friction forces in shearing within the material and on the contacting faces of pieces. To decrease the risk of thermal damages in creep-feed grinding, ultrasonic vibration (as a lubricant) was given to Aluminum 7075 and to Steel X210Cr12 workpieces in the direction of feed movement in dry creep-feed up-grinding while using vitrified aluminum oxide wheel. Grinding forces and surface quality are compared. It was found that under ultrasonic, without using coolant, the grinding forces were reduced and surface quality was improved. Under no ultrasonic sever thermal over-cut and burns were observed on steel, whilst there was no sign of such effects on aluminum.
