Cutting tools and its Characteristics
Cutting tool is a device, used to remove unwanted materials
from given work piece for carrying out the machining
process, cutting tool is fundamental and requirement
A cutting tool must have the following characteristics:
Hardness
Hot Hardness
Toughness
Requirements of Cutting tools
Tools must resist abrasive wear.
It must be capable of supporting and retaining smooth,
sharp edges.
They must be rigid
Cutting and clearance angles must be carefully selected.
Types of Tool materials
High Speed Steel (HSS)
High Carbon Steel (HCS)
Cast Alloy
Cemented Carbide
Ceramic
Diamond
Cobalt
Types of Cutting tools
Cnc milling tools
A machine operation in which a work part is fed past a
rotating cylindrical tool with multiple edges (milling
machine).
HSS with Titanium-nitride coated end mills.
Climb milling.
Cobalt premium end mills.
Milling tools
T – 15 cobalt premium steel ball Various types of cutters used in
End single End mill CNC Milling machine
CNC Turning tools
Turning is a machining process in which a cutting tool,
typically a non-rotary tool bit, describes a helical tool path by
moving more or less linearly while the work piece rotates
Types of tools:
Indexable insert tools
Standard brazed tools
Standard Brazed Single point Carbide
tools
straight Turning
Lead Angle Turning
Square Nose
Pointed Nose
Threading
Offset Threading
End Cutting Offset
Side Cutting Offset
Round Shank Boring
Square Shank Boring
Types of tools
CNC Drills
Drilling is a process of producing a round holes in a solid material or
enlarging a existing holes with the use of multi-tooth cutting tools called
drills or drill bits. Various cutting tools are available for drilling, but the most
common is the twist drill.
Types of Drill bits
Coolant Feeding Drill bits
Inserts
Inserts are removable cutting tips, which means they are not
brazed or welded to the tool body
They are usually indexable
This saves time in manufacturing by allowing fresh cutting
edges
The strength of the inserts also depends upon the shape of
the inserts
