【 摘 要 】

The machining performance of the CrAlSiN coating deposited on the micro router was evaluated by cutting printed circuit board (PCB). Two CrAlSiN coating systems, including commercial one and the one by pulsed cathodic arc evaporation (CAE) technology were deposited. The arc source current input is set by modulating the arc source current in the range of 90 and 120A, as compared to the constant current of 90A. CrAlSiN coating with the pulsed current input presents the highest hardness which is triple times higher than that of tool material. After the cutting PCB in dry condition, the microtool with CrAlSiN coating deposited by pulsed arc current exhibited the best cutting performance related to the cutting distance.
