Hello everyone, I'm debugging an electric linear actuator as a CNC electronic gear follower, synchronously feeding with the spindle.
During no-load simulation, the following ratio is precise and without deviation. However, when a real workpiece load is applied, a slight following lag always appears at the linear output, and the synchronous linear trajectory is slightly deformed, affecting the workpiece docking accuracy.
Recalculating the transmission ratio, tuning the servo closed-loop gain, and optimizing the CNC synchronization timing parameters have not completely eliminated the lag.
It seems the actuator's dynamic feed response is not keeping up with the intelligent follower's rhythm. I'm seeking practical tuning ideas from experienced professionals.
