· CNC machining is a highly utilised subtractive manufacturing technology. Computer numerical control systems offer less need for manpower and higher levels of automation. One of these automated fabriion methods is CNC is a process where rotary cutters remove material, which makes it the opposite of CNC turning.. The milling centres do not just perform the cutting .
processes, and what their tolerance producing capability is. After taking EML2322L, the students should have a tangible understanding of the tolerances associated with basic manufacturing processes used in this course ( milling, turning, drilling, reaming, bandsaw cutting, etc.)
