10.2.6 Special axes
Significance
In contrast to geometry axes, no geometrical relationship is defined between the special axes.
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
GEOAX() ; The geometry axis assignment defined via the machine
data
MD AXCONF_GEOAX_ASSIGN_TAB
is effective,
i.e., XX, YY and ZZ become geometry axes.
GEOAX (1, U, 2, V, 3, W) ; U, V and W become the first, second and third
geometry axes.
G1 X10 Y10 Z10 XX=25 ; Channel axes U, V, W each traverse to position 10, XX
traverses to position 25.
GEOAX(0,V) ; V is again removed from the geometry axis grouping. U
and W remain geometry axes. The second geometry axis
is no longer assigned.
GEOAX (1, U, 2, V, 3, W) ; U, V and W become the first, second and third
geometry axes, i.e., U and W remain unchanged.
GEOAX(3,V) ; V becomes the third geometry axis. This means that W,
which was previously the third geometry axis, is
removed from the geometry axis grouping. The second
geometry axis is no longer assigned.
Note
Geometry axes have an exactly defined relationship in the form of a rightangled coordinate
system.
