||Tool lives of the inserts and product quality of the surface were studied. Work was divided in two main part: Tool life experiment and product quality experiment.
A milling machine DMU 70 V with a constant flow of compressed air as cooling condition was employed all over the experiment.
In tool life experiment, a number of coated carbide indexable inserts were tested over stainless steel 316L specimen. Hardness measurements were carried and hardened skin was removed in order to reduce the influence of this parameter.
Different ranges of cutting parameters were selected and tool wear measured at intervals during tests. All data were reported to be elaborated.
Product quality experiment concerned the study of some of the most used roughness parameters in order to evaluate the "surface quality" subjected to different working condition.
Different cutting parameters and different insert wear grades were tested.
Data resulted seem to highlight that time can be saved (in the order of 500%) selecting values for the cutting parameters higher 100% than the usual recommended in data handbooks and manuals, roughness parameters staying practically the same.
It was also found that is possible to last working life of the inserts to VB = 0.5mm without involve the surface quality
