Abstract
The purpose of this study was to clear the conditions for good performance in dry cutting of aluminum alloys with non-hydrogenated diamond-like carbon (DLC) coated tool. The intermittent and continuous cutting tests were conducted under dry condition to 4 types of aluminum alloys. Consequently, it was found out that DLC coated tool showed good performance in intermittent cutting of A5052 and A7075 (Wrought aluminum alloys), but it didn't show good performance in intermittent cutting of AC2A and AC8A (Aluminum castings) and in continuous cutting of A5052 and AC2A. It was thought that the disappearance of DLC coating on the tool rake face caused adhesion in cutting of aluminum castings and continuous cutting of wrought aluminum alloys.
