Verification on Chaotic Behavior of Cutting Force in Metal Cutting

절삭가공시 절삭력 신호의 카오스적거동에 관한 규명

So far the analysis and modeling of cutting process is studied commonly assumed as being linear stochastic or chaotic without experimental verification. So we verified force signals of cutting process(ball end-milling) is low-dimensional chaos by calculating Lyapunov Exponents. reconstructing attractor using time delay coordinates and calcula-ting it's fractal dimension.
