Circular arc ccw G12/G13

G12 and G13 move the tool in a circular arc at the feed rate to the
end point. The center dimensioning is absolute.
Direction of rotation:
G12: In clockwise direction
G13: In counterclockwise direction
Parameters:
X: Diameter
Z: Target point
R: Radius (0 < R <= 200000)
I: Center absolute (radius dimension)
K: Center absolute
Q: Intersect. pt. or Final point if the circular arc intersects a line
segment or another circular arc (default: 0)
0: Near point of intersection
1: Far point of intersection
BR: Chamf./round. – defines the transition to the next contour
element
When entering a Chamf./round., program the theoretical end
point.
No entry: Tangential transition
BR = 0: No tangential transition
BR > 0: Rounding radius
BR < 0: Width of chamfer
BE: Special feed rate factor for Chamf./round. (default: 1)
Special feed rate = active feed rate * BE (range: 0 < BE <= 1)
Programming:
X and Z absolute, incremental, modal or ?
