Summary
Path information:
Instruction Meaning
G90 Coordinate input with absolute dimensions
G91 Coordinate input with incremental dimensions
G00 Linear motion with rapid traverse
G01 Straight line interpolation with defined speed
G02 Circular interpolation clockwise
G03 Circular interpolation anti-clockwise
All the above departure commands are modal.
Interpolation Meaning
parameter
I Circle centre coordinate in X,
incremental from starting point
J Circle centre coordinate in Y,
incremental from starting point
K Circle centre coordinate in Z,
incremental from starting point
The interpolation parameters are operative block-by-block
Mixed programming for coordinate input:
IC(...) Incremental dimension input
AC(...) Absolute dimension input
The statements IC(...) and AC(...) are valid only for the address preceed-
ing them.
Example:
Instruction Meaning
X=IC(10) Traverse by 10 mm in X
Y=AC(20) Traverse to 20 mm in Y
