Abstract:
In the age of market economy it 1S essential that the production
cost of any part has to be minimum to make competitive in the
global market. From this point of V1ew tool geometry plays an
important role in manufacturing economy. Tool geometry has
influence on wear .rate and, therefore, on tool 1 ife, also on
product ion costs. The knowledge of se1ect ing appropr iate too 1
geometry and other cutting conditions for various application 1S
almost absent in the relevant industries of our country at
different cutting conditions. The cutting speed range was selected
to cover the critical cutting speed at which built up edge vanishes
from the tool surface during cutting. Tool wear is also found to
have minimum value near the critical cutting speed.Experiment were
conducted with various parameters of the tool geometry with a view
to determining their optimum values.The optimum values of these
angles were determined from the condition of minimum intensity of
tool wear criterion. It has been established that intensity of tool
were can be reduced quite appreciably ( 3 to 4 times) by proper
selection of tool geometry. In the present work the tool geometry
parameters were varied one by one, so there remains a scope for
further works by varying two or more paraeters together. The
present work attempts to present a method of selecting optimum tool
geometry for turning stainless steel with cemented carbide cutting
