摘要：A mechanism and method for adjusting the position of a cutting insert relativeto the body of a cutting tool is disclosed. The mechanism of the invention comprises apair of flexible cantilevered walls each defining a wall of cutting insert pocket in the bodyof a boring bar. A boring bar of the invention comprises a bar body having at least onepocket for receiving a cutting insert and a position-adjusting mechanism including a pairof flexible cantilevered walls each defining a wall of the pocket. In the method of theinvention, a boring bar is provided having a plurality of pockets each defined by a pair ofcantilevered walls adapted to be flexed by a wedge mechanism. Next, a cutting insert isinstalled into each pocket. The position of the cutting edge of each cutting insert is thendetermined. In the last step of the method, the radially inwardmost insert is adjustedoutward by using the wedge mechanism to flex the cantilevered walls.
