N2 - The purpose of this study was to investigate factors affecting the variation of friction coefficient in intermittent cutting of aluminum alloy A5052 with non-hydrogenated diamond-like carbon (DLC) coated tool. The orthogonal intermittent cutting tests using workpieces that have different length of cutting parts (L1) and different clearance of cutting parts (L2) were conducted. Additionally, the orthogonal intermittent cutting tests under O2, N2 and air blow were conducted. There was an area where no aluminum adhered on the tool rake face after all tests in which friction coefficient decreased. It was cleared that the decrease of friction coefficient in the latter stage of the intermittent cutting depended on the actual cutting distance, Much aluminum adhered on the tool after the test under O2 blow. On the other hand, little aluminum adhered and the friction coefficient decreased in the test under N2 and W Mow.
