摘要: Abstract The effect of different Wire electrical discharge machining (WEDM) process parameters on the damping behavior A356.2 aluminum alloy is investigated. In present investigation pulse time (TON), off (TOFF) and peak current (IP) which are considered to be most significant from previous studies varied using one factor at a approach, study alloy. Damping experiments performed dynamic mechanical analyzer (DMA 8000) constant strain under dual cantilever mode over frequency range 1–100 Hz room temperature. scanning electron microscope was used for characterization wire EDMed samples. Experimental results reveal that greatly depends EDM parameters. related mechanisms presented.
