Milling Machine Operations

Milling Machine Operations Points : Milling Machine Operations Following different operations can be perform on milling machine:
1. Face Milling Operation
2. Straddle Milling Operation
3. Side Milling Operation
4. Plain Milling Operation
5. Angular Milling Operation
6. Gang Milling Operation
7. Profile Milling Operation
8. Form Milling Operation
9. End Milling Operation
10. Slot Milling Operation
11. Gear Cutting Operation
12. Saw Milling Operation
13. Cam Milling Operation
14. Thread Milling Operation
15. Helical Milling Operation
1. Face Milling Operation Face milling operation make flat surface at face on workpiece. Surface is perpendicular to surface prepared in plain milling operation. This operation is performing by face milling cutter mount on stub arbor of milling machine. Depth of cut is set according to require and cross feed is given to work table.
2. Straddle Milling Operation Straddle milling operation is like to side milling operation. Two side milling cutters are mount on equal arbor. Distance among them is so adjusted to equally sides of workpiece can milled at the same time. Hexagonal bolt can create by this operation by turning workpiece just two times as this operation produce two parallel faces of bolt at the same time.
3. Side Milling Operation Side milling operation makes flat and vertical surfaces at sides of workpiece. In this operation depth of cut is familiar through adjusting vertical feed screw of workpiece.
4. Plain Milling Operation Plain milling operation is also called slab milling. These operations make flat surfaces on workpiece. Feed and depth of cut are select, rotating milling cutter is motivated as of one end of workpiece to other end to complete the one pairs of plain milling operation.
5. Angular Milling Operation Angular milling operation is use to make angular surface on workpiece. The created surfaces make an angle by the axis of spindle which is not right angle. Production of V shaped groove is exemplar of angular milling opration.
6. Gang Milling Operation Gang milling operation makes several surfaces of workpiece concurrently using a gang of milling cutters. Through this operation, workpiece mount on table is fed beside the revolving milling cutters.
7. Profile Milling Operation Profile milling operation a pattern of difficult shape or master die is use. Tracer and milling cutter are coordinated jointly by respect to their movements. Tracer reads pattern or master die with milling cutter make the similar shape on workpiece. Profile milling is an operation use to make shape of a pattern or die.
8. Form Milling Operation Form milling operation is produces irregular curve on work surface. These irregular curve can be convex, concave, or of any other shape. This operation is completed fairly at very low cutter speed than plain milling operation.
9. End Milling Operation End milling operation make flat vertical surfaces, flat horizontal surfaces and further flat surfaces make an angle as of table surface by milling cutter name as end mill. This operation is if possible carried out on vertical milling machine.
10. Slot Milling Operation Slot milling operation make grooves, keyways, slots of unstable shapes with sizes is calling slot milling operation. This operation can use any kind of milling cutter similar to plain milling cutter, metal slitting saw or side milling cutter. Choose of a cutter depends upon kind and size of slot or groove to be created. Right placement milling cutter is extremely main in this operation as axis of cutter must be at middle of geometry of slot or groove to be created.
11. Gear Cutting Operation Gear cutting operation is cutting of uniformly spaced, identical gear teeth on gear blank by handling it on a universal dividing head with then indexing it. Cutter use for this process is cylindrical type or end mill type. Cutter selection too depends upon tooth profile with their spacing.
12. Saw Milling Operation Saw milling operation make narrow slots or grooves in workpiece using saw milling cutter. This operation is too use to cut workpiece into two equal or unequal pieces which cut is too identified as parting off. Lest of parting off operation cutter with workpiece are set in way so to the cutter is directly located above one of the T slot of worktable.
13. Cam Milling Operation Cam milling operation is use to make the cam on milling machine. In this operation cam blank is mount at the end of dividing head spindle with the end mill is held in vertical milling attachment.
14. Thread Milling Operation Thread milling operation make threads using thread milling centres. This process requires three concurrent movements revolving movement of cutter, concurrent longitudinal movement of cutter, feed movement to workpiece through table. For every thread, revolving cutter is fed longitudinal with a distance equivalent to pitch of thread. Depth of cut is usually adjusted equal to full depth of threads.
15. Helical Milling Operation Helical milling operation is make helical flutes or grooves on the edge of cylindrical or tapering workpiece. This is perform through swiveling table to necessary helix angle, then rotating and feeding the workpiece beside revolving cutting edges of milling cutter. Drill, helical gears and reamers are finished by this operation.
