4.13 Simple Linear and Circular Movements
4.13 Simple Linear and Circular
Movements
Linear path G1
G1 moves the tool on a linear path at the feed rate to the “end point.”
Parameters
X End point (diameter)
Z End point
A Angle (angular direction: see help graphic)
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 factor for chamfer/rounding arc (default: 1)
Special feed rate = active feed rate * E (0 < E <= 1)
Programming X, Z: Absolute, incremental, modal or “?”
