使用计算机数字控制(CNC)连续轨迹坐标磨床加工,能够可靠地保证淬硬模具上的精密孔系和连续曲面的技术要求,并能消除不同型面交接处不光滑的弊病,所以应用效果是显著的. 一、加工模具的工艺过程图1是冷冲模的型腔图,它是由圆弧和直径构成的连续曲面;凹凸模的间隙(单边)为0.003mm,材料为Cr12MoV,硬度为HRC58～60,凹模在CNC连续轨迹坐标磨床上加工的曲面工艺过程如表1所示. 二、CNC连续轨迹的编程 CNC连续轨迹坐标磨床的工作是按照一定的程序对工件型面进行磨削.因此,磨削之前,由专门的数 The use of computer numerical control (CNC) continuous path coordinate grinding machine, can reliably ensure the precision of the hardened mold holes and continuous surface of the technical requirements, and can eliminate the different types of interface junction matte ills, so the application effect is significant The process of processing the mold Figure 1 is a cavity diagram of the cold die, which is continuous surface composed of arcs and diameters; the gap (unilateral) of the punch and die is 0.003mm, the material is Cr12MoV, the hardness is HRC58 ~ 60, the die in the CNC continuous path coordinate grinding machine surface process shown in Table 1. Second, the CNC continuous path programming CNC continuous path coordinate grinding machine work is in accordance with certain procedures on the workpiece surface grinding. Therefore, before grinding, by the number of specialized
