Optimising the application

Machining accuracy on a moving workpiece can be increased by carrying out the following measures:

  1. A highly constant conveying velocity results in optimised feedforward control. By contrast, strongly fluctuating feed rates lead to greater position errors since feedforward control assumes a constant velocity.
  2. The smaller the system delay time, the smaller the influence of feed rate fluctuations on position accuracy, see also CNC scheduling. Delay time can be defined using the display variable synchro_lag.
