Circular path
G2, G3 – incremental midpoint dimensions
G12, G13 – absolute midpoint dimensions
The tool moves in a circular arc at the feed rate to the “end point“.
Parameters
X, Z:
End point (X diameter)
R: Radius
Q: Point of intersection – default: Q=0
B: Chamfer/rounding
• B left undefined: Tangential transition
• B=0: Nontangential transition
• B>0: Rounding radius
• B<0: Chamfer width
E: Special feed rate – no input: active feed rate
With G2, G3:
I, K:
Midpoint incremental (distance start point – midpoint;
I diameter)
With G12, G13:
I, K:
Midpoint absolute (I diameter)
Example: Circular path G2
Example: Circular path G12
