Circular interpolation
8.4.1
Circular interpolation: G2, G3
Functionality
The tool moves from the starting point to the end point along a circular path. The direction is determined by the G function:
G2: clockwise
G3: counter-clockwise
The description of the desired circle can be given in various ways:
See the following illustration for possibilities of circle programming with G2/G3 using the example of the axes X/Y and G2:
G2/G3 remains active until canceled by another instruction from this G group (G0, G1, ...).
The
path velocity
is determined by the programmed
F word
.
