Further information
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). LookAhead
deceleration is applied before corners and blocks with exact stop.
Corners are also traversed at a constant velocity. In order to minimize the contour error, the
velocity is reduced according to an acceleration limit and an overload factor.
