Answer:
A decrease in feed rate results in better surface roughness, which causes slightly faster tool wear; an increase in cutting speed produces better surface roughness and higher tool wear.

Explanation:
A decrease in feed rate results in better surface roughness, which causes slightly faster tool wear; an increase in cutting speed produces better surface roughness and higher tool wear. Regenerative vibration accelerates tool wear resulting in poor surface roughness and tool life.
