Reducing Cutting Force Induced Bore Cylindricity Errors by Learning Control and Variable Depth of Cut Machining
(The American Society of Mechanical Engineers (ASME), 1998)In this paper, a method for on-line compensation of cylindricity errors in machined bores is formulated and demonstrated. The cylindricity errors addressed are those caused by the elastic ... -
Multi-Category Classification of Tool Conditions Using Wavelet Packets and ART2 Network
(The American Society of Mechanical Engineers (ASME), 1998)This paper proposes a new approach for multi-category identification of turning tool conditions. It uses the time-frequency feature information of the AE signal obtained from best-basis wavelet ... -
Process Mean Shift Detection Using Prediction Error Analysis
(The American Society of Mechanical Engineers (ASME), 1998)Autocorrelation in 100 percent measurement data results in false alarms when the traditional control charts, such as X and R charts, are applied in process monitoring. A popular approach proposed ... -
A General Formulation for Hydroforming of Arbitrarily-Shaped Boxes and Its Application to Hydroforming of an Elliptic-Circular Box
(The American Society of Mechanical Engineers (ASME), 1998)A general kinematically admissible velocity field is suggested for the upper-bound solution of hydroforming of arbitrarily-shaped boxes. The suggested formulation is then applied to hydroforming ... -
An Integrated Model of the Material Handling System and Unit Load Design Problem
