| Abstract |
| The effect of incorporating Zr02 and TiC on different mechanical
properties as well as the performance of alumina based ceramic cutting
tools has been studied. Along with the mechanical properties
of the tool materials, the importance of tool geometry and the effect
of different cutting parameters, viz. cutting speed, feed and depth of
cut, on the tool life have also been discussed. It was observed
that these tools were useable successfully even at a cutting speed of
350 m/min and up to that limit, the increase in cutting speed had a
slightly negative effect on their performances while the wear rate was
found to be more sensitive to the variation of depth of cut. Addition
of TiC and Zr02 improved their performances for the applications
requiring very high speed and high depth of cut respectively. |
