An experimental investigation of abrasive waterjet milling circular pocket of titanium alloy

摘要

An effective semi-empirical model based-on material removal rate is proposed for milling depth-controlled circular pockets. Experiments are conducted to research the effect of various processing parameters (e.g. traverse speed, water pressure, stand-off distance, abrasive flow rate), on the performance of the milled circular pockets for Ti6Al4V workpieces. The article presents a comparative analysis of the average milling depth which is dominated by several dimensionless variables defined by the processing parameters that control the final performance involved in the milled circular pocket. An experimental validation has been carried out and the model predictions are in good agreement with experimental results.
