4.6 Basic Contour Elements
Starting point of turning contour G0-Geo
G0 defines the starting point of a turning contour.
Line segment in a contour G1-Geo
G1 defines a line segment in a turning contour.
Example: G0-Geo
. . .
FERTIGTEIL [FINISHED PART]
N2 G0 X30 Z0 [starting point of contour]
N3 G1 X50 B-2
N4 G1 Z-40
N5 G1 X65
N6 G1 Z-70

Parameters
X Contour starting point (diameter value)
Z Contour starting point
Parameters
X End point of contour element (diameter value)
Z End point of contour element
A Angle to rotary axis (for angle direction see graphic support
window)
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
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
E Special feed rate for the chamfer/rounding arc during the
finishing cycle (default: 1)
Special feed rate = active feed rate * E (0 < E <= 1)
