Therefore, it greatly affects the machining efficiency and quality. Thus, a corner smoothing transition algorithm based on double cubic NURBS, which is curvature-continuous and satisfies the given accuracy constraint, is proposed to smooth the local corner at the adjacent five-axis linear path. On the basis of the smoothing transition model, the parametric synchronization between the smoothed double NURBS trajectories and the remaining two linear segments are respectively constructed to realize the smoothing variation along the tool tip translational trajectory and tool axis rotational trajectory. The simulation and examples show that the proposed transition algorithm can satisfy the error constraints, reduce the feedrate fluctuation, and improve the machining quality"},{"@xml:lang":"sl","#text":"Petosne poti orodij so pogosto sestavljene iz linearnih segmentov s tangentnimi nezveznostmi v ogliščih, zaradi česar se tangencialna hitrost v ogliščih med sosednjima segmentoma sunkovito spreminja ali je enaka nič.
