2.7 Units—Finishing
"Transverse finishing with direct contour input"
unit
The unit finishes the contour defined by the parameters in one pass.
In EC you define whether you want to machine a normal or a plunging
contour.
Unit name: G890_G80_P / Cycle: G890 (see page 282)
Access to the technology database:
 Machining operation: Finishing
 Affected parameters: F, S, E
Contour form
EC
Type of contour
 0: Normal contour
 1: Plunging contour
X1, Z1 Contour starting point
X2, Z2 Contour end point
RC Rounding: Radius of contour corner
AC Start angle: Angle of the first contour element
(range: 0° < AC < 90°)
WC End angle: Angle of the last contour element
(range: 0° < WC < 90°)
BS Chamfer/radius at start:
 BS>0: Radius of rounding arc
 BS<0: Section length of chamfer
BE Chamfer/radius at end
 BE>0: Radius of rounding arc
 BS<0: Section length of chamfer
Cycle form
E
Plunging behavior
 E>0: Plunging feed rate for declining contour elements.
Descending contour elements are machined.
 No input: The plunging feed rate is reduced during
machining of declining contour elements by up to 50%.
Descending contour elements are machined.
B Switch on TRC (type of tool radius compensation)
 0: Automatic
 1: Tool to the left (G41)
 2: Tool to the right (G42)
DXX Additive correction numbers 1 – 16
G58 Contour-parallel oversize (radius)
Further forms: see page 58
With the address Dxx you activate an additive
compensation for the entire cycle run. The additive
compensation is switched off again at the end of the cycle.
You edit additive compensation values in the Program Run
mode of operation.
