Abstract

Hybrid manufacturing consisting of metal additively manufactured preforms and computer numerical control (CNC) machining has been established to be an effective method for higher material use rates than traditional manufacturing methods. However, hybrid manufacturing introduces unique challenges. Near-net shape designs are typically selected, which results in a smaller margin for part placement within the stock. Consequently, when moving the workpiece between deposition and machining systems, the work coordinate system must be maintained to ensure part placement. Additionally, less stock material reduces the preform stiffness, which limits the material removal rates during machining. To date, a comprehensive digital twin methodology to accurately predict the machining outcome has not been presented.
