Which outcome results when using excessive downfeed on a CNC lathe?

💡 Explanation

Chatter develops because excessive downfeed overloads the cutting tool, magnifying vibrations through the **machine tool resonance**; therefore, chatter ruins surface finish, increasing tool wear, rather than improving part quality, as lighter cuts would mitigate this.
