Abstract: | The chatter vibration stands for a sudden relative vibration appeared between a material and a tool while processing with
a machine. This vibration is a factor that seriously affects the quality of processed materials as well as being a factor
which causes serious damages to the tool and the machine. This study is related to the detection and compensation of chatter
vibration that can compensate chatter vibration faster and produce processed goods with more precision by autonomous compensation.
The above-mentioned chatter vibration compensator includes the chatter vibration sensor and the chatter compensator that estimates
the compensation value according to the sensor detecting the chatter vibration of machine tool and the chatter vibration detected
from the sensor while having a feature of being organized by interlocking with the machine tool controller. |
