Electromagnetic Actuator for Determining Frequency Response Functions of Dynamic Modal Testing on Milling Tool

Machine tools are the main driving forces of industrialization of a country. However, poor machinability because of chatter vibration results in poor surface quality, excessive noise, and reduced material removal rate. Modal testing is a useful method to investigate dynamic properties of a cutting t...
