This paper presents a novel corner smoothing local method for computer numerical control machine, which effectively reduces cycle time and interpolates micro-line trajectory accurately.
This paper presents a novel corner smoothing local method for computer numerical control machine. Under normal circumstances, most tool path is made up of hundreds or thousands of tiny straight segments called G01. Then, local smoothing is achieved by interpolation through splines or curves that are well-known to us. In this study, a new technique for corner smoothing is realized directly under kinematic limits and geometric constraints. Instead of utilizing the familiar local corner smoothing that are acquainted with the academic research of predecessors and accumulated experience in practice, employing this novel algorithm accurately gains smoother cornering trajectory, acceleration, and stabilized velocity such that delivers an optimal motion. Experimental validation explicitly demonstrates effectiveness of reducing cycle time and interpolate precisely for micro-line trajectory in machining.
