在用直接仿形法工作的仿形磨床上加工特形表面时,在型面的特定区段上产生具有系统特性的波纹。这种机床仿型装置的传动系统示于图1 a、δ。在图1 a中,与靠模1同轴地安装在摇架4之顶针上的零件3以固定不变的角速度ω转动,完成仿形运动S_t;这时,砂轮2作切削运动、进给运动并有振动。 When machining a relief surface on a profiling grinder operating with direct profiling, system-specific moiré is produced on specific sections of the profiling. The transmission system of this machine profiling device is shown in Figure 1 a, δ. In Fig. 1a, the part 3 coaxially mounted on the thimble of the cradle 4 with the master 1 is rotated at a constant angular velocity ω to complete the copying movement S_t; at this time, the grinding wheel 2 is subjected to a cutting movement, feeding Exercise and vibrate.
