How do I know if I am using the correct feed rate?

Whilst this is important for all types of material being cut, I will focus on metals because they seem to cause the most problems.

Chips are the pieces of material that have been cut away and can be the best clue to incorrect feed rates. If they are powdery, then increase the feed rate. If they have a blue colour (burnt) then decrease the feed rate. If they are free-curling and not discoloured, then the feed rate is right.

Increasing the feed rate will produce bigger chips. Increasing the band speed will make more teeth pass through the cut per minute ensuring a smoother cut.

If you are cutting wood and it is burning - reduce the feed rate, use a courser tooth or give me the blade for sharpening - or all three
