3.2.2.38 G101 Polar coordinates: linear interpolation
The preparatory function G101 corresponds in function to the preparatory
function G01 during the programming of the target positions in the
rectangular coordinate system.
G101 AXES U W F E L
AXES Center coordinates
U Polar radius
W Polar angle
F Path speed
E, L Selection of feed speed via speed (E) and increment (L). F=E*L.
The center of the polar coordinate system is defined by two addresses: X/Y
for G17, X/Z for G18, Y/Z for G19. The assignment of the principal axes can
be changed with G16. When the axes U and W are used as main axes, these
cannot be used for the center programming.
The center coordinates can be programmed in absolute dimensions or in
incremental dimensions.
The target position is defined by the polar radius U and the polar angle W in
reference to the current center.
The radius and the angle can be programmed in absolute dimensions or in
incremental dimensions.
The programmed center coordinates have a modal effect.
The preparatory function G101 has a modal effect.
