In this study, an orthogonal intermittent machining test for aluminum alloy 5052 was conducted under dry conditions. By using cutting forces that were measured during the test, the frictional properties of a tool rake face were evaluated during intermittent machining for two types of diamond-like carbon (DLC)-coated tools and an uncoated carbide tool. DLC films used in the test were composed of tetrahedral amorphous carbon (ta-C) deposited by a filtered arc deposition process and hydrogenated amorphous carbon (a-C:H) deposited by a plasma-enhanced chemical vapor deposition process. The test results showed that the initial friction coefficients were approximately 0.8 for all tools. However, with increasing machining time, the friction coefficient of only the ta-C-coated tool decreased remarkably to a lower value of 0.3, whereas those of the a-C:H-coated tool and the uncoated carbide tool remained high. An electron probe micro analyzer (EPMA) analysis revealed an area where no aluminum adhered on the ta-C-coated tool rake face after intermittent machining. This area provided low frictional properties during intermittent machining. An X-ray photoelectron spectroscopy (XPS) analysis showed that the carbon bonding of the DLC film surface in this area had changed from the state before machining.
