Detailed Description
2.4 Tool: Tool radius compensation 2D (TRC)
Tool Compensation (W1)

Axes
The continuity condition is observed in all three axes. It is thus possible to program a
simultaneous path component perpendicular to the compensation plane for
approach/retraction.
Only linear blocks are permitted for the original approach and retraction blocks with
KONTT/KONTC. These programmed linear blocks are replaced in the control by the
corresponding polynomial curves.
Exception
KONTT and KONTC are not available in 3D variants of tool radius compensation (CUT3DC,
CUT3DCC, CUT3DF).
If they are programmed, the control switches internally to NORM without an error message.
Example for KONTC
The two figures below show a typical application for approach and retraction with constant
curvature:
The full circle is approached beginning at the circle center point. The direction and curvature
radius of the approach circle at the block end point are identical to the values of the next
circle. Infeed takes place in the Z direction in both approach/retraction blocks
simultaneously.
The associated NC program segment is as follows:
$TC_DP1[1,1]=121 ; Milling tool
$TC_DP6 [1,1] = 10 ; Radius 10 mm
