ABSTRACT:
A boring bar includes an insert pocket formed on the back side of a relief in the working end of the bar, for the removable installation of a cutting insert therein. The insert pocket may be formed to provide a positive rake angle for the insert installed therein, relative to the axis of the bar, and further may include a positive angle relative to the radius of the bar as well. The force imparted to the insert as the bar is forced against the workpiece, tends to force the insert upwardly and inwardly into the pocket of the bar, thus assisting in holding and securing the insert to the bar. The bar is also thicker at the upper portion of the insert pocket than at the lower portion of the pocket, thus providing additional strength and stiffness to the bar in this critical area to reduce the possibility of chatter and breakage of the bar. Either the tool moves and the workpiece is stationary, or the workpiece moves and the tool is stationary.
