HEIDENHAIN CNC PILOT 4290 7
Line segment G171 Geo
G171 defines a line segment in a contour of the XY plane.
”Chamfer/rounding B” defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point of the contour element.
”Intersection selection Q” specifies the end point if the path
intersects an arc and the end point is not defined.
Parameters
X, Y: End point (X radius dimension)
A: Angle to positive X axis
B: Chamfer/rounding
■ B no entry: Tangential transition
■ B=0: Nontangential transition
■ B>0: Radius of rounding
■ B<0: Width of chamfer
Q: Select point of intersection – default: 0
■ Q=0: Near intersection
■ Q=1: Far intersection
