G112-Geo
Circular arc in lateral surface contour G112-/G113-Geo
G112/G113 defines a circular arc in a lateral surface contour. The
direction of rotation is visible in the help graphic.
Parameters
Z, C: End point, end angle
CY:
End angle as linear dimension
R: Radius
K: Center point (in Z direction)
W: Angle of the center point
J: Angle of the center point as a linear value
Q: Selection of intersection – default: 0
■ Q=0: Far intersection
■ Q=1: Near intersection
B: Chamfer/rounding
■ B is undefined: Tangential transition
■ B=0: Nontangential transition
■ B>0: Rounding radius
■ B<0: Chamfer width
• Program either Z, C or Z and CY, or K, W or K and J.
• Program either center or radius.
• For radius: only arcs
† 180° possible
