What is the lathe of the knife phenomenon
First, the processing system (including the lathe body, turning, the workpiece) due to the lack of rigidity, due to the impact of cutting force, causing deformation.
Second, due to the poor stiffness of the material processing, even if the tool is completely accurate design by the size of the workpiece, but because of the deformation of the workpiece will produce thick, thin, the size of the phenomenon of tolerance.
There is a machine tool screw itself has a gap, there will be a knife phenomenon.
