Predictive Modeling of Thermally Assisted Machining and Simulation Based on RSM after WAAM

The WAAM (Wire Arc Additive Manufacturing) process is well-respected because of its low cost and high deposition efficiency; nevertheless, the has limitations heat input forming accuracy. Hybrid manufacturing processes employing both additive subtractive can effectively reduce shape error. predictive modeling surface roughness in thermally assisted machining described this paper on basis three important parameters: feed per tooth, spindle speed, workpiece temperature. model indicates that temperature a very significant influence quality. An experimental study was performed to obtain variation law cutting quality with order determine optimal interval processes. Through finite element simulation machining, external main force internal mean stress material were determined.
