Continuous-path mode, G64
In continuous-path mode, the tool travels across tangential contour transitions with as
constant a path velocity as possible (no deceleration at block boundaries). Look Ahead
deceleration takes place before corners (G9) and blocks with exact stop (Look Ahead, see
following pages).
