Abstract
In this study, cutting performance of a small end mill tool in high-speed milling of the austenitic stainless steel (SUS304) was investigated. In addition, the effect of improvement in smoothness of coated film on tool life was also examined. As a result, the tool life was remarkably improved at a high-speed of 16.7m/s compared with 2.5m/s. It is clarified that tool life of coated tool without droplet was twice times in that of commercial coated tool with droplet.
