"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 290)
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)
 3: Automatic, without tool angle compensation
 4: Tool to the left (G41), without tool angle compensation
 5: Tool to the right (G42), without tool angle
compensation
HR Main cutting direction
 0: Automatic
 1: +Z
 2: +X
 3: -Z
 4: -X
SX, SZ Cutting limit (SX: diameter value)—(default: no cutting limit)
Further parameters of the contour form: see page 62
Cycle form
Q
Type of approach (default: 0)
 0: Automatic selection—the Steuerung 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.
