Starting point of contour G170 Geo
G170 defines the starting point of a contour in the XY plane.
Linear element G171 Geo
G171 defines a line segment in a contour of the XY plane.
Parameters
X
Starting point of contour (radius)
Y Starting point of contour
Parameters
X
End point (radius)
Y End point
A Angle to positive X axis
B Chamfer/rounding. Defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point.
„ No entry: Tangential transition
„ B=0: No tangential transition
„ B>0: Rounding radius
„ B<0: Chamfer width
Q Point of intersection. End point if the line segment intersects
a circular arc (default: 0):
„ Q=0: Near point of intersection
„ Q=1: Far point of intersection
Programming X, Y: Absolute, incremental, modal or “?”
