Resumo

The objective of this work is to compare, through tool life tests and surface finishing of the workpiece machined in SAE
4340 steel turning, surface modified carbide inserts of class ISO P by means of laser texturing and blasting (commercial process ),and then coated with TiN (titanium nitride). The results showed a better average performance in the life tests of the laser textured inserts and a better finish of the turned part with the use of the TiN coating, both for the sandblasted and laser textured substrate in relation to the uncoated tool.
