Abstract
Deformation of directed energy deposition (DED) is an index to reflect the relationship among fabricating quality, parameters and process method. In the present work, Inconel 718 cylindrical walls are manufactured by hybrid additive and subtractive manufacturing (HASM) to investigate the deformation. In-situ and off-line measurements are used to detect the deformation of the cylindrical walls with laser displacement measurement sensor and precision contact probe. The finite element simulation is used to analyze the relationship among the temperature, stress and deformation. The effect of different interlayer dwell times (from 0 to 45 s) on residual stress and deformation are compared. The deformations of different positions and processing parameters are analyzed.
