Abstract
This paper investigates the recycling waste aluminum alloy 6061 from high speed machine (HSM) machine using hot forging process. Hot forging process able to recover the grain structure of material by controlling certain pressure and temperature. The experiments conducted by Taguchi method design. Three factors selected are chip size, operating temperature and operating pressure with three levels for each factor. Both factors for operating temperature and pressure direct control from hot forging machine. The chip sizes are prepared from HSM machine using by three machine parameters, which are constant cutting speed and manipulate three levels for each parameter for feed rate and depth of cut. The final result between reference and experiment specimen shows the close gap in the tensile test. The main effect, signal noise ratio and analysis of variance were employed to investigate the results and the optimum parameters for hot forging process can be established. It can be concluded that the hot forging process able to recycle waste (chip) aluminum compared to the current recycling aluminum process.
