Radial force can cause vibration or deformation of workpiece in internal turning process

especially for deep hole turning

which have a negative effect on machining accuracy and surface quality. In this paper

the impact damper theory is investigated and the damped turning cutter is designed. Firstly

the impact damper theory is investigated via modeling and simulation based on Euler–Bernoulli beam theory. Then

the clearance and restitution coefficient are optimized via simulated annealing algorithm with different cutting parameters. The negative real part of the main mode of the damped turning cutter is maximized

which can achieve the stability of cutting process. Finally

the damped turning tool is designed based on impact damper theory and th

e cutting test is carried out. When n=400r/min

f=0.1mm/r

a

p

=0.4 mm

the experimental results show that the vibration acceleration amplitude can be decreased from 46.5m/s

to 4.0m/s

and the roughness can be decreased from 4.62μm to 1.95μm.
