Multifunction Operations

The groove-turn are multifunction tools, able to operate in a sequence of grooving and turning modes. Moving from turning to grooving requires consideration of the basic Grip principle, thereby eliminating the possibility of insert breakage. In this situation one must release the side deflection which is necessary in turning, but not recommended in grooving. Not recommended The following machining sequence is suggested: After completing the longitudinal turning, but before starting the grooving, the side deflection must be released. Move the tool in the direction opposite that 0.1mm of feed, approximately 0.1 mm, and return to the original position without side load.

Then, after the deflection has been released and the holder is perpendicular to the workpiece, the grooving operation may start.
