Abstract: The basic problem in modal analysis of machine tool structures is the extraction of modal parameters from the measured transfer function data. Conventionally this task is performed in two steps. ...

Abstract: The feasibility of a newly proposed method for the removal of cutter marks in die finishing operations has been investigated. The method is based on the superposition of a tertiary motion ...

Abstract: An analytical model has been developed to investigate the drill wandering motion quantitatively. It has been shown mathematically why the resulting distorted polygon-shaped hole always has an odd ...

Abstract: The principles of a new in-process measurement and control system for flatness errors in machining have been introduced. The laser-based system consists of a stylus, a geometrical table measurement ...

Abstract: A new experimental method for three-dimensional cutting analysis based on times series models and the Dynamic Data System methodology is introduced. Its theoretical formulation allows the treatment ...

Abstract: A two-stage, time-domain structural dynamics identification method, that circumvents some of the main drawbacks of current techniques, and combines good noise rejection properties with a low ...

Abstract: Despite the well-established theories and considerable experimental research, the identification of the complex mode shapes of a real machine tool structure with general damping still remains a ...

Abstract: A fast, on-line algorithm for machining process modeling and control is proposed. The modeling is accomplished via a new recursive estimator that offers good accuracy at a minimal computational ...

Abstract: A sensitivity analysis of the discrete-to-continuous transformation used in the “indirect” modeling of continuous-time systems from sampled experimental data is presented. For the transformation of ...

Abstract: Many efforts have been devoted in the past to the identification of the dynamic behavior of the cutting process. Nevertheless, there have been no consistent results due to the inherent complexity ...
