  Interrupted cutting is a demanding internal machining condition in which the cutting edge repeatedly engages and disengages from the workpiece, causing sudden changes in cutting forces. Keyways, slots, cross-holes, grooves, uneven surfaces, and irregular internal features can create such conditions. If the boring bar is unsuitable, repeated impacts may cause vibration, insert chipping, premature tool wear, poor surface finish, dimensional variation, or tool failure. Selecting the right boring bar therefore requires consideration of rigidity, material, overhang, insert geometry, cutting parameters, machine stability, and workpiece characteristics to maintain stable and consistent machining performance.
