Research on Wire-Electro Discharge Machining of SiC Particle Reinforced Cu Matrix Composite
The law of peak current, pulse width and working voltage parameter etc which influencing on wire-electro discharge machining (WEDM) cutting speed and surface roughness of the SiC particle reinforced Cu matrix composite in the WEDM machining were studied; the machined surface of Cu matrix composite was analyzed by means of scanning electron microscope (SEM); SiC Particle reinforced Cu matrix composite microstructure was analyzed by means of metallographic microscope. The results show that the first factors are peak current and pulse width, the second is working voltage. While pulse interval has reached a certain degree, pulse interval has slightly influence on surface roughness. If peak current is higher and pulse width is narrower, the wire electric discharging machining is ideal for matrix composite.
