What
is the difference between face milling and end milling?
These
are two of the most prevailing milling operations, each using different types
of cutters –the face mill and the end mill. The variance between face milling
and end milling is that an end mill used both the end and the sides of the
cutter, whereas face milling is used for horizontal cutting.
1.
Endmill
These tools used have a flat bottom but not always. Round and radiuses cutters are also available. End mills are similar to drills in the intellect that they can cut axially. But the favorable of milling lies in the possibility of lateral cutting.
2.
Face mill
The
face mills cutter cannot cut axially. Instead, the cutting edges are always
situated on the sides of the cutting head. The cutting teeth are refundable
carbide inserts.
This
makes the life of a tool longer while maintaining a good cutting quality.
3.
Ball cutter
Ball cutters, also known as ball mills, have hemispherical cutting tips. The objective is to maintain a corner radius for vertical faces.
4.
Woodruff cutter
Woodruff
or keyset/keyway cutters are used to cut key slots into parts, for example,
shafts. The cutting tools have teeth upright to the exterior diameter to
generate suitable slots for Woodruff keys
5.
Roughing end mill
As
the name says, these are moderately many end mills with a slight dissimilarity.
The roughing end mill has notched teeth. These make the cutting progress faster
than with a regular end mill.
The cut bits of metal are littler than ordinary and therefore easier to clear. Multiple teeth come into the junction with the workpiece at the same time. This restores chatter and vibration, which could otherwise be larger because of the serrated teeth.
6.
Involute gear cutter
There
is a special cutting tool for milling roller gears. There are separate cutters
available to generate gears within a certain number of teeth.
7.
Fly cutter
These
tools have the same performance as face mills. They comprise a central body
that holds either one or two tool bits (double-end fly cutters).
Face
mills cutter are better for high-quality cutting. The fly cutters are just
cheaper and the cutting bits are often made at the shop by a machinist rather
than buying from stores.
8.
Hollow mill
Hollow mills are fundamentally against face mills. Here, the workpiece is fed into the internal parts of the mill to generate a cylindrical outcome.
9.
Slab Mill
This kind of cutter is used when you have to remove more amount of material from the workpiece. By using roughing end mills, we obtain a rough surface Roughing finishing end mills are also famous as “ripped” cutters. They are more helpful commercially and are used in various industrial applications.
10.
Woodruff cutter
Woodruff
or keyset/keyway cutters are used to cut key slots into parts, for example,
shafts. The cutting tools have teeth upright to the exterior diameter to
generate suitable slots for Woodruff keys.
11.
Thread mill
The
name of this tool says everything you need to know about its aim. Thread mills
are used for showing tapped holes.
Threading
operations are usually carried out on drilling apparatus. Using a thread mill,
though, is more fixed and has few limits regarding the environment.

Milling Key Ways,
Grooves, and Slots
1.
Side Milling
It
is the machining process that generates a flat vertical surface at the sides of
a workpiece. This operation is completed by using a side milling cutter.
2.
Plain Milling
It is a Progress of milling plane surfaces keeping the axis of the cutter parallel to the surface being milled. It is also called slab milling or surface milling. A plain milling cutter is used for the plain milling.
3.
Face Milling
This operation makes plane surfaces on the face of the workpiece. This machining operation is done on surfaces that are perpendicular to the axis of the cutter. The operation is achieved by the face milling cutter fixed on the stub arbor of the machine.
4.
Straddle Milling
it
is an operation in which two side milling cutters are used to machine two
adverse sides of a workpiece simultaneously. The straddle milling process is
shown in the figure given below.
5.
Angular Milling
It
is an operation of milling flat surfaces which are neither Parallel nor upright
to the axis of the milling cutter. It is also called angular milling. A
single-angle milling cutter is used to perform this process.
6.
Gang Milling
It
is a machining operation in which two or more milling cutters are used together
to perform different milling processes simultaneously. In gang milling, the
cutters are fixed on the arbor.
7.
Form Milling
It
is the operation of machining a special contour (outline) composed of straight
lines, curves, or entirely of curves, at a single cut. Formed milling cutters
shaped to the contour to be cut are used to complete this operation. This
operation is completed by using convex, concave, and corner circular milling
cutters.
8.
Profile Milling:
This
milling process is used to cut a profile on the workpiece.
9.
End Milling
It is the operation of generating flat surfaces which may be vertical, horizontal, and at any angle taking the worktable as a reference. End milling cutters are used to complete this process.
10.
Saw Milling
It
is a machining operation that is used to generate narrow grooves or slots on
the workpiece.
It
is also used for dividing the workpiece into two equal or unequal parts.
This
milling process is performed by using a saw milling cutter.
The
width of the cutter is very less as compared with the width of the workpiece.
11.
Milling Key Ways, Grooves, and Slots
This
milling process is used to generate key ways, grooves, and slots on the
workpiece.
12.
Gear Milling
It
is the milling process that is used to cut gears on the workpiece. This
operation is done by using conceived milling cutters called involute gear
cutters.
13.
Helical Milling
This
milling operation is done to generate objects having a helical design such as
helical gears, twisted drills, etc. it is done on the outside of the
cylindrical workpiece.
14.
Cam Milling
It
is a machining operation that is used to make cams. The cams are used to open
and close the valves in the I.C. Engines (internal combustion engines).
15.
Thread Milling
It
is the operation of milling used to cut threads on the cylindrical workpiece.
