What are the different types of milling operations?

Milling operations is a process of producing flat and complex shapes with the used of multi tooth cutting tool.

operations

Axis rotation of the cutting tool is perpendicular to the direction of feed either parallel to perpendicular to the machined surface.

Milling is an interrupted cutting operation the teeth of the milling cuter enter and exit the work during each revolution.

Machining of flat surfaces,key ways,Slots,pockets and profile.

cutting tools – HSS CARBIDE.

Surface finish achievable (RA value in microns ):3.2

Machine both conventional and CNC type.

Main types of conventional machine.

  • Plain milling machines.
  • Horizontal milling machine.
  • vertical milling machine.

OTHER TYPES OF CONVENTIONAL MACHINES

  • Universal milling machine.
  • Ram type milling machine.
  • Bed type milling machine.

OPERATIONS

FACE MILLING

  • By face milling cutter

END MILLING

  • By end mill cutter
  • For machining pockets slots,key way,etc

SIDE AND FACE MILLING

  • By side and face milling cutter.

FORM MILLING

  • By form milling cutter.

ANGULAR MILLING

  • Angle milling cutter or fitting spindle head in vertical.

SLITTING

  • By metal slit saw.

GEAR CUTTING

  • Formed tooth cutter with dividing head.

KEY WAY MILLING

By plain milling cutter or end milling cutter.

HELICAL MILLING:

Will produce grooves and prosphery of cylindrical work,reamer/Drill flutes cam grooves.

PROFILE MILLING:

By a ball nose cutter on CNC Milling machine (Both 2d and 3d profiles)
