USER GUIDE 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, GROOVE-TURN 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. Prior move Actual move Machining Between Walls One of the most important advantages of the and repeat same cycle leaving steps GROOVE-TURN systems is the ability to machine of 0.2 mm at the shoulders for the finishing cut. between walls. To achieve the best results, the Minimum D.O.C. has to be ap≥Rx1.2 (corner radius). following sequence is recommended: Finishing Roughing Plunge on the right side, reaching the tangent of the Plunge to depth of cut. Pull back 0.2 mm radially. bottom radius. Retract and relieve the tangent point of Turn longitudinally, retract at the end of the cut by 0.2 mm, the radius on the other side. Retract and machine simultaneously in radial and axial directions. Plunge again all of the contour, pulling back by compensation value along the bottom (see page 346).
