M.; Yerramareddy, S.; Lee, S. M.; Lu, S. C.-Y.淡江大學航空太空工程學系Fairfield: ASME InternationalJournal of Dynamic Systems, Measurement, and Control 113(2), pp.273-279This paper presents a methodology which employs computer simulation to dynamically generate the topography of a surface machined during an intermittent turning process. The methodology is based on a mathematical model that characterizes the intermittent turning process as an alternating sequence of forced and free vibratory motion. The simulation of machining workpieces, with discontinuous geometries of arbitrary shape, is facilitated by representing the workpiece surface as a two-dimensional grid, with an index for each cell in the grid accounting for the feature boundaries. The tool vibratory motion is integrated with the tool geometric motion to form a ba
