
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)
M02
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
/(G02 X40 Y40 R40)

7. G03 Counterclockwise Circular Interpolation
The same as G02. The difference is that G02 is clockwise circular(clockwise arc), but
G03 is counterclockwise circular(counterclockwise arc).
8. G40/G41/G42 Kerf Compensation
These functions are used for kerf compensation. Because flame incision and plasma
incision both finally have the existence of kerf when incise route expressed by code is
only actual size of work piece, the actual incision work piece without regard to the effect
of kerf isn’t needed size. After set the kerf compensation, the system will automatically
work out the effect of kerf and incise work piece with actual size.
G41/G42 must match with G40 to be used. If G41/G42 is ignored, the default kerf
compensation is zero; if G40 is ignored, kerf compensation is available.
