3.17 Pole coordinate instruction(G15/G16)
The end point coordinate value can be input in polar Coordinate (Radius & Angle).
The plus direction of the angle is counterclockwise of the selected plane first axis + direction ,
and the minus direction is clockwise.
Both radius & angle can be commanded in either absolute or incremental command(G90,G91).
Format: G G G16; Starting the polar Coordinate command(Polar Mode)
G IP_; Polar coordinate command
...
G15 Cancel Pole coordinate command;
G16 ; Polar Coordinate command
G15
; Polar coordinate command cancel
G ; Plane selection of the polar Coordinate command(G17,G18 or G19)
G ; G90 specifies the zero point of the work coordinate system as the origin of
the polar Coordinate system, from which a radius is measured. G91 specifies the current position as
the origin of the polar coordinate system,from which a radius is measured.
IP_
; Specifying the addresses of axes constituting the plane selected for the
polar coordinate system, and their values.
First axis: Radius of pole coordinate.
Second axis: Angle of pole coordinate.
Setting the zero point of workpiece coordinate system as origin of pole coordinate system:
Specify the radius(the distance between the zero point and the point) to be programmed with an
absolute command. The zero point of the work Coordinate system is set as the origin of the polar
coordinate system.When a local coordinate system(G52) is used, the origin of local coordinate
system becomes the center of polar coordinate. As the follow shown:
Setting the current position as the origin of polar coordinate system : Specify the radius (the
distance between the current position and the point) to be programmed with an incremental
command. The current position is set as the origin of the polar Coordinate system.
