Longitudinal roughing with direct contour input unit
The unit machines the contour defined by the parameters. In EC
you define whether you want to machine a normal or a plunging
contour.
Unit name: G810_G80 / cycle: G810
Further information: "Longitud. roughing G810", Page 317
Contour form:
EC: Type of contour
0: Normal contour
1: Plunging contour
X1, Z1: Start point contour
X2, Z2: End point contour
RC: Rounding – radius of contour corner
AC: Start angle – angle of the first contour element (range: 0°<
AC < 90°)
WC: Final angle – angle of the last contour element (range: 0° <
WC < 90°)
BS: -Chamfer/+radius at start
BS > 0: Radius of rounding arc
BS < 0: Width of chamfer
BE: -Chamfer/+radius at end
BE > 0: Radius of rounding arc
BE < 0: Width of chamfer
BP: Interval time – time span for interruption of the feed
The chip is broken by the (intermittent) interruption of the feed.
BF: Feed period – time interval until the next break
The chip is broken by the (intermittent) interruption of the feed.
Cycle form:
P: Maximum infeed
I, K: O-size X and Z
E: Plunging behavior
E = 0: Descending contours are not machined
E > 0: Plunging feed rate for descending contour elements.
Descending contour elements are machined
No input: The plunging feed rate is reduced during machining
of descending contour elements by up to 50 %. Descending
contour elements are machined
H: Contour smoothing
0: With each cut (within the infeed range)
1: With the last cut (entire contour) – retract at an angle
below 45°
2: No smoothing – retract at an angle below 45°
