介绍一种活塞环非圆轮廓曲线数控仿形技术及系统外界扰动信号的智能决策与模糊控制技术。以一个近似于二次谐波曲线的凸轮作为驱动刀具进给的正弦机构,进给行程通过调整杆杠来改变,可以在电机不反转的前提下,实现刀具进给运动,从而大大提高系统的频响;借助于调节电机速度,使刀具进给速度与主轴速度保持某种预定关系(与活塞环型号、规格有关),便可加工出不同型号和规格的活塞环零件;采用智能决策方法和模糊控制规则,形成专家智能控制系统,提高系统鲁棒性和工件的仿形加工精度。
A kind of intelligent non-circular contour curve profile control technology of piston ring and intelligent decision-making and fuzzy control technology of disturbance signals outside the system are introduced. A similar to the second harmonic curve of the cam as a sine tool driven feed mechanism, the feed stroke by adjusting the bar to change, you can not reverse the motor under the premise of the tool to feed movement, thereby greatly improving the system Of the frequency response; by adjusting the motor speed, the tool feed speed and the spindle speed to maintain a predetermined relationship (and piston ring models, specifications), can be processed into different types and specifications of the piston ring parts; using intelligent decision-making methods And fuzzy control rules, the formation of expert intelligent control system to improve system robustness and workpiece profiling accuracy.
