| The machining requirements of modern materials have given impetus to the
development of better cutting materials and alumina tools have come up to the
expectations. These tools offer a number of advantages in cutting because of their
resistance to heat & wear, high hot hardness and chemical inertness which prevent
surface welding and erosion by chips. But the efficient use of alumina cutting
tools require considerable improvements in the strength of the material, tool
geometry and machine tools. This paper review these developments and illustrates
how a better understanding of these tools can lead to many successful applications
with lower cost, increased productivity and improved cutting performance. |
