3.3.3.3
Rounding with maximum possible axial dynamic response (G644)
Function
Maximizing the dynamic response of the axes is key to this type of continuous-path mode with rounding.
Activation
Continuous-path mode with rounding with the maximum possible axial dynamic response can be activated in any
NC part program block by the modal command
G644
.
Selecting the exact stop which works on a block-by-block basis enables rounding to be interrupted (G9).
Continuous-path mode with rounding with the maximum possible axial dynamic response (G644) can be
deactivated by selecting:
• Modal exact stop (G60)
• Continuous-path mode G64, G641, G642, G643 or G645
Note
Rounding with G644 is only possible if:
• all the axes involved contain only a linear motion in both the observed blocks.
• no kinematic transformation is active
In case an involved axis contains a polynomial (polynomial programmed, spline active,
compressor active) or a kinematic transformation is active, the block transition is rounded
with G642.
