1.6 DIN PLUS: Contours in the YZ Plane

Circular arc G182/G183 Geo

G182/G183 defines a circular arc in a contour of the YZ plane. Direction

of rotation: See help graphic

Parameters

Y End point (radius)

Z End point

J Center (Y direction)

K Center (Z direction)

R Radius

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):

 For a transition to a line segment:

 Q=0: Near point of intersection

 Q=1: Far point of intersection

 For a transition to a circular arc:

 Q=0: Far point of intersection

 Q=1: Near point of intersection

Programming

 Y, Z: Absolute, incremental, modal or “?”

 J, K: Absolute or incremental

 End point must not be the starting point (no full circle).
