If the tool is set too high

• Increases the working clearance making the tool weak and prone to breaking and you can get tool chatter (affects finish and tool cutting point)

• Increases the working clearance and the tool will rub against the work piece affecting the finish

• Reduces the working clearance and the tool will rub against the work piece affecting the finish

• Reduces the working making the tool weak and prone to breaking and you can get tool chatter (affects finish and tool cutting point)

Safety features when working on the lathe are

• tie back long hair

• don't lean on the guards

• make sure the drill guard is in place

• know where the emergency stops are

Datums used on the lathe are

• face

• centre

a clearance fit is

• when the shaft is bigger than the hole

• when the hole is bigger than the shaft

• when the hole can be bigger or smaller than the shaft

an interference fit is when

• the shaft is always bigger than the hole

• the hole is always bigger than the shaft

• the shaft can be bigger or smaller than the hole

• the hole can be bigger or smaller than the shaft

a transition fit is

• when the hole is always bigger than the shaft

• when the shaft is always bigger than the hole

• when the hole can be bigger or smaller than the shaft

• when the shaft can be bigger or smaller than the hole
