    • A method includes receiving a representation of a spun tool (222) and receiving a path (240) for the spun tool (222). The method also includes calculating a profile of the spun tool (222) and simulating movement of the spun tool (222) over the path (240). The method includes determining critical positions (232, 234) along the path (240) at which the composition of the profile of the spun tool (222) changes based on the path (240), and re-calculating the composition of the profile of the spun tool (222) for each side of a critical position (232, 234). The method further includes re-calculating the shape of the profile of the spun tool (222) at non-critical positions (242, 244) of the path (240). The method further includes determining a volume (352) defined by moving the spun tool (222) along the path (240) between a first critical position (232) and a second critical position (234), changing the profile of the spun tool (222) at each critical position (232, 234), and calculating a total volume based on the path (240).
    • 一种方法包括接收纺丝工具(222)的表示并接收用于纺丝工具(222)的路径(240)。 该方法还包括计算纺丝工具(222)的轮廓并且模拟纺丝工具(222)在路径(240)上的移动。 该方法包括确定沿着路径(240)的临时位置(232,234),在该路径处,纺丝工具(222)的轮廓的组成基于路径(240)改变,并重新计算轮廓的轮廓的组成 所述旋转工具(222)用于临界位置(232,234)的每一侧。 该方法还包括在路径(240)的非临界位置(242,244)处重新计算纺机(222)的轮廓的形状。 该方法还包括确定通过在第一临界位置(232)和第二临界位置(234)之间沿着路径(240)移动纺织工具(222)来限定的体积(352),改变纺丝工具的轮廓 222)在每个临界位置(232,234)处,并且基于路径(240)计算总体积。

    • A simulation system (20) for a CNC machine tool includes a swept surface calculation engine (21) for processing workpiece data and grinding wheel data representing information about the grinding wheel (12) and its programmed path to generate a set of geometric envelopes representing the solid volume occupied by the grinding wheel (12) as it moves along its programmed path. The envelopes, workpiece data and grinding wheel data are processed by a 3-D rendering engine (22) to produce a three-dimensional perspective image of the workpiece (11) as it would appear after being ground by the grinding wheel (12). The simulation system (20) also includes a manipulation and control interface (23) which may be used for a wide variety of purposes to enhance the three-dimensional image, such as position, orientation and zoom control, control of simulated illuminated light sources, control of texture maps and colour maps and overlay grids which may be superimposed on the surface of the simulated workpiece image.
