Jn – displacement of circle centre’s Y coordinate relative to start point of current segment,
unit(mm);
R[-]n – the radius of arc, when the angle of arc <=180°, R is positive. Otherwise, it’s negative,
unit(mm);
(In the relative coordinate system):
Xn – displacement of endpoint’s X coordinate relative to start point of current segment,
unit(mm);
Yn – displacement of endpoint’s Y coordinate relative to start point of current segment,
unit(mm);
(In the absolute coordinate system):
Xn – displacement of endpoint’s X coordinate relative to working start point, unit(mm);
Yn – displacement of endpoint’s Y coordinate relative to working start point, unit(mm);
Example:
Example 1: B->A
G92 X0 Y0 // Reference point (0,0)
G91 // Relative coordinate
G00 X60 Y100 //Rapidly move tool to B
G02 X-40 Y-40 I0 J-40 //The arc 1
/(G02 X-40 Y-40 R-40)

Example 2: A->B
G92 X0 Y0 // Reference point (0,0)
G91 // Relative coordinate
G00 X20 Y60 //Rapidly move tool to A
G02 X40 Y40 I40 J0 //The arc 2

G03 Counterclockwise Circular Interpolation
The same to G02. The difference is that G02 is clockwise circular(clockwise arc), but G03
is counterclockwise circular(counterclockwise arc).
