The one of the major part of CNC Machine is Cutting tools or Inserts. We need to study the Cutting tools and its nomenclature throughly and also study the materials of Cutting tools and types of tools. The Cutting tools are used to remove unwanted materials in the workpiece and to provide a good finish for a customers need.So the Cutting tools is very important to CNC Machine, if there is no cutting tool in CNC Machine, there is no CNC Machine. So the cutting tools are very important to all CNC Machines

 Cutting tools and its Characteristics
 Requirements of cutting tools
 Types of Tool materials
 Types of Cutting tools
 CNC Milling tools
 CNC Turning tools
 CNC Drills
 Inserts

3. 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

4. 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.

5. Types of Tool materials
 High Speed Steel (HSS)
 High Carbon Steel (HCS)
 Cast Alloy
 Cemented Carbide
 Ceramic
 Diamond
 Cobalt

6. 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.

9. 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

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

14. 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.

15. Types of Drill bits

17. Coolant Feeding Drill bits

18. 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
