2.2 Units—Roughing
"Contour-parallel roughing in ICP" unit
The unit machines the contour described in the FINISHED program
section from "NS to NE" parallel to the contour. Any auxiliary contour
defined in FK will be used.
Unit name: G830_ICP / Cycle: G830 (see page 270)
Access to the technology database:
 Machining operation: Roughing
 Affected parameters: F, S, E, P
Contour form
J
Workpiece blank oversize (radius value)—active only if
no blank
has been defined.
B Contour calculation
 0: Automatic
 1: Tool to the left (G41)
 2: Tool to the right (G42)
Further parameters of the contour form: see page 60.
Cycle form
P
Maximum infeed
I, K Oversize in X, Z direction (I: diameter value)
SX, SZ Cutting limit (SX: diameter value)—(default: no cutting limit)
A Approach angle (reference: Z axis)—(default: parallel to Z
axis)
W Departure angle (reference: Z axis)—(default: orthogonal to
Z axis)
Q Type of retraction at end of cycle
 0: Returns to starting point, first X, then Z direction
 1: Positions in front of the finished contour
 2: Retracts to safety clearance and stops
H Type of cut lines (cutting paths)
 0: Constant cutting depth: Contour is shifted by a
constant infeed value (paraxial)
 1: Equidistant cutting lines: Cutting lines run at a constant
distant from the contour (contour parallel). The contour is
scaled.
HR Main machining direction
 0: Automatic
 1: +Z
 2: +X
 3: –Z
 4: –X
D Hide elements; do not machine form elements (see figure)
