摘　　要：传统的Voxel模型在处理多轴数控切削仿真时,不仅在判断是否发生切削上会耗费大量的运算时间,而且数据点的存储也占据了较大的内存空间,不能满足实时快速仿真的要求;在压缩体素模型构造方法中,虽然能够满足多轴数控切削仿真的要求,且存储空间较小,模型重构速度较快,但是在切削判断上的布尔运算量较大,间接影响了数控仿真的实时性。针对以上方法的不足,提出一种基于Voxel改进模型的三维实体建模方法,在显示速度和切削判断上都能够较好地满足数控实体仿真的实时性。In the process of dealing with the cutting calculation of Multi-axis CNC Simulation, the traditionalVoxel Model not only will cost large computation time when judging whether the cutting happens or not, but also the data points may occupy greater storage space. , so it is not able to meet the requirement of real-time emulation; In the construction method of Compressed Voxel Model, it can satisfy the need of Multi-axis CNC Simulation, and storage space is relatively small, also the model reconstruction speed is faster, but the Boolean computation in the cutting judgment is very complex, so it affects the real-time of CNC Simulation indirectly. Aimed at the flaws of above means, the paper proposes a improved solid modeling way based on the Voxel model, it can meet the demand of real-time in cutting computation and Graphic display speed.
