Parameters
G64 Continuous-path mode
G641 Continuous-path mode with programmable transition rounding
G642 Transition rounding with axial tolerance, with modal activated
G643 Block-internal corner rounding
G644 Corner rounding with greatest possible dynamic response
ADIS=... Rounding clearance for path functions G1, G2, G3, etc.
ADISPOS=... Approximate distance for rapid traverse G0
Note
Rounding cannot be used as a substitute for smoothing (RND). The user should not make
any assumptions with respect to the appearance of the contour within the rounding area.
The type of rounding can depend on dynamic conditions, e.g., on the tool path velocity.
Rounding on the contour is therefore only practical with small ADIS values. RND must be
used if a defined contour is to be followed at the corner without exception.
ADISPOS is used between G0 blocks. This enables the axis movement to be smoothed
substantially and the traversing time to be reduced during positioning.
If ADIS/ADISPOS is not programmed, a value of zero applies and the traversing behavior
therefore corresponds to G64. The rounding clearance is automatically reduced (by up to
36%) for short traversing distances.
Example
With this workpiece, the two outside corners at the groove are approached exactly. All other
machining takes place in continuous-path mode.
