G03 Circular Interpolation

Counterclockwise

Format

N... G02/G03 X... Z... I... K... F...

N... G02/G03 X... Z... B... F...

X, Z ............ End point of the arc (absolute or incre-

mental)

I, K .............. Incremental circle parameter

(Distance from the start point to centre

of arc, I is related to X, K to Z-axis)

B ................. Radius of the arc (arc smaller than

semicircle with +B, larger than semicir-

cle with -B), can be entered instead of I,

The tool will be traversed to the end point along

the defined arc with the programmed feed F.

Note

Programming the value 0 for I or K can be omitted.

The position of the circle end point will be checked, a

tolerance of 100 µm (computing and rounding errors)

is allowed.

According to DIN 66025 the observation of G02, G03

is always behind the turning axis, no matter whether

machining occurs behind or in front of the turning

axis.
