2.7 Units—Finishing
2.7 Units—Finishing
"ICP contour finishing" unit
The unit finishes the contour described by ICP from "NS to NE" in one
pass.
Unit name: G890_ICP / Cycle: G890 (see page 280)
Access to the technology database:
 Machining operation: Finishing
 Affected parameters: F, S
Contour form
B
Switch on TRC (type of tool radius compensation)
 0: Automatic
 1: Tool to the left (G41)
 2: Tool to the right (G42)
SX, SZ Cutting limit (SX: diameter value)—(default: no cutting limit)
Further parameters of the contour form: see page 58.
Cycle form
Q
Type of approach (default: 0)
 0: Automatic selection—the control checks:
 Diagonal approach
 First X, then Z direction
 Equidistant around the barrier
 Omission of the first contour elements if the starting
position is inaccessible
 1: First X, then Z direction
 2: First Z, then X direction
 3: No approach—tool is located near the starting point of
the contour area.
H Type of retraction. Tool backs off at 45° against the
machining direction and moves to the position I, K (default:
3):
 0: Diagonal
 1: First X, then Z direction
 2: First Z, then X direction
 3: Stops at safety clearance
 4: No retraction motion (tool remains on the end
coordinate)
I, K Cycle end position Position that is approached at the end of
the cycle (I diameter value).
