7.2. POLAR COORDINATES
The format of the axis coordinate values is as follows:
. In mm
R+/- 4.3 A+/-3.3
R+/- 4.3 A+/-3.3
. In inches:
R+/-3.4 A+/-3.3
R+/-3.4 A+/-3.3
R being the value of the radius and A the value of the angle (A in degrees), referred to the
polar center.
polar center.
When turning on and after M02,M30 EMERGENCY or RESET, the CNC takes the point
X0 Z0 as polar origin. The polar origin can be altered by G95.
X0 Z0 as polar origin. The polar origin can be altered by G95.
The values of R and A will be absolute or incremental depending on whether G90 or G91
are active.

When programming rapid (G00) or linear interpolations (G01), the values of R and A must
be entered.

When a circular interpolation (G02,G03) is programmed, the values of the angle A+/-3.3
of the arc’s final point and the values of the arc’s center referred to the starting point must
be entered.

When working with polar coordinates, the center of the circle on circular interpolations
(G02,G03) is defined with I,K same as working with cartesian coordinates.
