New synchronous control technology based on double closed-loop zero-error hardware interpolation and its application

基于现代集成锁相环路技术,提出了一种新型双闭环零误差硬件插补同步控制原理,用于机床具有联动要求的电轴运动控制,开发了精密电轴同步运动控制传动装置.在前苏联"5Д833"型蜗杆砂轮磨齿机床的数控化改造项目上得到应用.实际齿轮加工试验表明:提出的新型双闭环零误差硬件插补同步运动控制原理是正确可行的,齿轮加工精度可稳定在6～5级(GB10095-88).

A new principle named double closedloop zeroerror interpolation based on modern phaselockloop technology is put forward. This technology has been applied in the reconstruction of gear grinding machine of '5Д833' type. Gear machining experiment results show that the new type of interpolation is correct, practicable, and the machining precision can reach to 6～5 grade (GB1009588).
