2.1.6 Special axes
Significance
In contrast to geometry axes, no geometrical relationship is defined between the special
axes.
Note
Geometry axes have an exactly defined relationship in the form of a rightangled coordinate
system.
Special axes are part of the basic coordinate system (BCS). With FRAMES (translation,
scaling, mirroring), special axes of the workpiece coordinate system can be mapped on the
basic coordinate system.
Application
Typical special axes are:
• Rotary axes
• Machine tool axes
• Tool revolver axes
• Loader axes
2.1.7 Path axes
Meaning
Path axes are interpolated together (all the path axes of a channel have a common path
interpolator).
All the path axes of one channel have the same acceleration phase, constant travel phase
and delay phase.
The feedrate programmed under address F (path feedrate) applies to all the path axes
programmed in a block, with the following exceptions:
• An axis has been programmed that has been defined as having no control over the path
velocity with instruction FGROUP.
• Axes programmed with instructions POS or POSA have an individual feedrate setting (axis
interpolator).
Application
Path axes are used to machine the workpiece with the programmed contour.
