3.1.1 Work plane programming by two directions (G20)
Besides the main planes, any other work plane/trihedron formed by
the first three axes of the channel may be defined using function G20.
Programming
The work plane is defined by selecting the abscissa and ordinate axes,
the perpendicular axis and the longitudinal axis of the tool. It is
selected by assigning one of the following parameters to the axes
programmed with G20.
"1" To the 1
st
axis of the work plane (abscissa axis).
"2" To the 2
nd
axis of the work plane (ordinate axis).
"3" To the longitudinal axis of the tool and also perpendicular
(helical) axis of the plane if parameter 5 is not defined.
"4" Reserved.
"5" To the axis perpendicular to the work plane; if not
defined, it is the same as the longitudinal axis. Only when
the longitudinal tool axis is the same as the abscissa or
ordinate axis.
G20 X1 Z2 Y3
X It is the first main axis.
Z It is the second main axis.
Y It is the longitudinal axis of the tool and the
perpendicular axis.
G20 X1 Y2 X3 Z5
X It is the first main axis and the longitudinal
axis.
Y It is the second main axis.
Z It is the third main axis or perpendicular
axis.
