Constraint-driven local deformation optimization method for toolpath in the singularity region of five-axis machining

Five-axis CNC machining plays a crucial role in manufacturing complex freeform surfaces with high precision and efficiency. However, when the tool axis vector enters a singular region, abrupt rotary axis motion occurs, causing severe degradation of machining accuracy and surface quality. To address...
