Most of these codes surely express the turning insert shape like C = C Shape Turning Insert D = D Shape Turning Insert K = K Shape Turning Insert R = Round Turning Insert S = Square Turning Insert T = Triangle Turning Insert V = V Shape Turning Insert W = W Shape Turning Insert The picture tells us more about turning inserts shapes. The general turning insert shape play a very important role when we choose an insert for machining. Not every turning insert with one shape can be replaced with the other for a machining operation. As C, D, W type turning inserts are normally used for roughing or rough machining. As a cnc machinist I will use C type turning insert with Roughing Cycle (G71 G72 for Fanuc cnc control), And I will choose D type turning insert for Finishing Cycle(G70 for Fanuc ). 2 = Turning Insert Clearance Angle General Turning Insert Clearance-Angle General Turning Insert Nomenclature Clearance-Angle The second letter in general turning insert nomenclature tell
