3.2.2.37 G100 Polar coordinates: linear interpolation, high rate
The preparatory function G100 corresponds in function to the preparatory
function G00 during the programming of the target positions in the
rectangular coordinate system.
G100 AXES U W
AXES Center coordinates
U Polar radius
W Polar angle
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 G100 has a modal effect.
N100 G17
N110 G0 X50 Y0
N120 G100 X10 Y10 U20 W45 The zero point offset of the Z axis (tool length) is set in T1 to
50 mm here.
