| Abstract | ||
| Tool geometry play an important role in mechanical machining and surface finish of workpiece. So there are many parameters such as cutting speed ,feed rate ,and tool nose radius that are known to have a large impact on surface quality,however there are many more parameters that have an effect on the surface roughness . this paper fouced on effect of tool nose radius on surface roughness and run out which causes tool chatter, the experments prove that high values of nose radius causes rough surface with high value of run out also in this paper use seven different values of nose radius of cutting tool were(0.3,0.4, 0.5. 1 , 1.5, 2, 2.5mm) under different of cutting conditions ( such as feed rate ,cutting speed , depth of cut ) Results show that good surface finish at nose radius (0.4, 0.5 )mm which lead to reduce tool chatters, work run out during machining another calculations were done theoritically for arithmetic roughness which have a small difference with experimentally tests and increasing of roughness and run out at values less than (0.3mm). | ||
