Description
The tool movement programmed with G0 is executed at the highest possible speed (rapid
traverse). The rapid traverse speed is defined separately for each axis in machine data. If
the rapid traverse movement is executed simultaneously on several axes, the rapid traverse
speed is determined by the axis, which requires the most time for its section of the path.
Traversing path axes as positioning axes with G0
Path axes can travel in one of two different modes to execute movements in rapid traverse:
• Linear interpolation (behavior in earlier SW version):
• Non-linear interpolation:
With non-linear interpolation, the setting for the appropriate positioning axis BRISKA, SOFTA
or DRIVEA applies, with reference to the axial jerk.
4-12
The path axes are interpolated together.
Each pat axis is interpolated as an individual (positioning) axis independently of the other
axes involved in the rapid traverse movement.
