A milling operation which involves the use of a combination of more than two cutters, mounted on a common rotor for milling a number of flat and vertical surfaces of a work-piece simultaneously is called Correct Answer Gang milling

Concept:

Milling with a combination of several milling cutters with different diameters is called gang milling and they are mounted on a common rotor as shown in the figure below.

The operation performed by gang milling cutters is called gang milling.

By gang milling, a profile of different shapes can be milled in one operation.

Additional Information

  • Straddle Milling:
  • When the milling is performed on two surfaces simultaneously it is called straddle milling.
  • In Straddle milling, two side milling cutters are mounted with the desired distance between them so that both sides of a work piece can be milled simultaneously.
  • A straddle is a special form of gang milling where only side and face milling cutters are used.
  • In Straddle milling, two side milling cutters are mounted with the desired distance between them so that both sides of a workpiece can be milled.
