INVESTIGATION OF THE MACHINING PERFORMANCE OF ALUMINUM-BRONZE ALLOY IN WEDM USING TAGUCHI METHOD

Abstract

Aluminum-Bronze alloys (Al-10%-Cu-balance) are difficult-to-machine cut alloys. Copper (Cu) metal itself is not suitable for machining. The machining performance of the Aluminum-Bronze alloy sample was investigated by the Wire Electric Discharge Machining (WEDM) method, which is among the non-traditional manufacturing methods used in conductive materials that are difficult to process. The aluminum-bronze sample with a diameter of 20mm was cut with 0.18mm molybdenum wire electrode. Table feedrate, pulse-on-time and pulse-space were used as experimental parameters. Surface roughness and energy consumption values were measured in WEDM process. According to Taguchi analysis and ANOVA results, it was determined that the pulse-on-time parameter was effective on the surface roughness and the table feedrate parameter was effective on the energy consumption.
