Look-ahead velocity control
In the continuous-path control mode with G64, the control system automatically determines
the velocity control for several NC blocks in advance. This enables acceleration and
deceleration across multiple blocks with approximately tangential transitions. For paths that
consist of short travels in the NC blocks, higher velocities can be achieved than without look
ahead.
