【Abstract】 The geometric modeling techniques and mathematical calculations of the points of intersection in CNC simulation field are the key techniques in the CNC simulation system.So this paper mainly talks about the object-space separating modeling technique based on the triangular grids,and brings forward simplification calculation of the points of intersection between semi-finished material and cutting scanning body,which reduced calculation quantities in simulation,increased the speed of simulation and optimized the effect of simulation.更多还原
