2.2 Units—Roughing
"Bidirectional roughing in ICP" unit
The unit machines the contour described in the FINISHED program
section from "NS to NE" parallel to the contour and bidirectionally. Any
auxiliary contour defined in FK will be used.
Unit name: G835_ICP / Cycle: G835 (see page 271)
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 58.
Cycle form
P
Maximum infeed
I, K Allowance in X and Z direction (I = diameter)
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.
D Hide elements; do not machine form elements (see figure)
