Every shift
To maintain proper coolant levels and concentrations, and to ensure a machine tool has sufficient
lubrication, a machinist should check the machine's fluids:
G01
Which code identifies linear interpolation (feed in a straight line)?
Follow all safety rules at all times
Your employer has appointed you to work with the safety committee to develop a department safety
