1. G Function Description
1.2.11 G15/G16 POLAR COORDICATES
COMMAND MODE
Command form:
G16;
//Start polar coordinate mode
G __ X _ Y _
：
：
//Polar coordinate command

G15;
//Cancel polar coordinate command
X: polar coordinate radius
Y: polar coordinate angle( “＋” for CW, ”－” for CCW)
Description:
start polar coordinate mode in first line, G16 for polar coordinate
command start, G15 for polar coordinate command cancel, it can use polar
coordinate mode to enter position(radius and angle), G90/G91 can specify
in it. First address is radius, second address is angle. Absolute or increment
is decided by G90 or G91, G90 is absolute, G91 is increment, in absolute
mode, the increase of radius or angle from origin point; in increment mode,
angle or radius total from the last radius or angle.
