Determination of Machinability and Abrasive Cutting Properties
Modern abrasive waterjet machines require precise parameter settings to meet the everincreasing precision demand. Machinability and abrasive index are two important parameters for abrasive waterjet cutting. The latest software uses a cutting model that takes the inputs of machinability, abrasive index, and other process parameters to predict the jet behavior so that compensation can be made to improve the part accuracy. The methodology to determine the values of machinability and abrasive index is becoming more crucial than ever. Improper methodology can lead to large discrepancy in the data of machinability and abrasive index as well as cutting results. This paper will present a methodology in determining machinability and abrasive index.
