6. Interpolation Functions
Detailed description
(1) G02 (or G03) is retained until another G command (G00, G01 or G33) in the 01 group that
changes its mode is issued.
The arc rotation direction is distinguished by G02 and G03.
G02 Clockwise (CW)
G03 Counterclockwise (CCW)
Y
(2) An arc which extends for more than one quadrant can be executed with a single block
command.
(3) The following information is needed for circular interpolation.
(a) Plane selection................... : Is there an arc parallel to one of the XY, ZX or YZ planes?
(b) Rotation direction ............... : Clockwise (G02) or counterclockwise (G03)?
(c) Arc end point coordinates .. : Given by addresses X, Y, Z
(d) Arc center coordinates ....... : Given by addresses I, J, K (incremental commands)
(e) Feed rate ............................ : Given by address F
