Tool for chip removing machining having a wedge-actuated insert adjustment mechanism

A method for chip removing machining, the method utilizing a base body presenting an insert seat adapted to receive a cutting insert, the base body including first and second fixed support surface structures disposed adjacent to the seat;

• and an insert adjusting mechanism disposed on the base body adjacent to the seat, the adjusting mechanism including first and second jaws and a movable wedge member positioned between the jaws for spreading the jaws away from one another by a selected distance;
• the first jaw including a front surface facing in a first direction toward the seat, and a first pressure surface structure facing in a second direction generally opposite the first direction, the front surface adapted to engage a cutting insert and define a support position therefor;
• the second jaw including a second pressure surface structure facing generally in the second direction, the method comprising the steps of:
• A) positioning the jaws in a first position wherein the first pressure surface structure engages the first support surface structure, and the second pressure surface structure is spaced from the second support surface structure, the front surface of the first jaw defining a basic support position for the insert, and
• B) actuating the wedge member to spread apart the jaws, to cause the second pressure surface structure to engage the second fixed support surface structure and displace the first jaw in the first direction, while maintaining engagement between the first pressure surface structure and the first support surface structure, wherein the front surface of the first jaw is displaced to define an adjusted support position.
