Circular arc ccw G2/G3
G2 and G3 move the tool in a circular arc at the feed rate to the end
point. The center dimensioning is incremental.
Direction of rotation:
G2: In clockwise direction
G3: In counterclockwise direction
Parameters:
X: Diameter
Z: Target point
R: Radius (0 < R <= 200000)
I: Center, incremental (radius value)
K: Center, incremental
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 ?
