The factor considered for evaluation of machinability is
* cutting forces and power consumption
* tool life
* type of chips and shear angle
The factor considered for evaluation of machinability is
* cutting forces and power consumption
* tool life
* type of chips and shear angle
In machining metals, surface roughness is due to
* feed marks or ridges left by the cutting tool
* fragment of built-up edge on the machined surface
* cutting tool vibrations
The surface finish is improved by the increase in
* cutting speed
* nose radius
* true rake angle
