When rotating the slender shaft, the causes of deformation and vibration are as follows:
(1) The workpiece is bent and deformed by cutting thermal elongation.
(2) The workpiece bends and vibrates under the action of cutting force.
(3) Vibration caused by dead weight and deformation of workpiece.
(4) Under the action of centrifugal force, the bending and vibration of the workpiece are aggravated.
The solutions adopted include:
(1) Use the central frame;
(2) Use the tool heel;
(3) Reduce thermal deformation;
(4) Reasonably select the geometry and cutting parameters of the turning tool.
