Angle of inclined wheel $TC_TPG8
This parameter specifies the angle of inclination of an inclined wheel in the current plane. It
is evaluated for GWPS.

Note
The tool lengths are not automatically compensated when the angle is altered.
The angle must be within the range -90° ≤ $TC_TPG8 < +90°.
On inclined axis machines the same angle must be specified for the inclined axis and the
inclined wheel.
Parameter number for radius calculation $TC_TPG9
This parameter specifies which offset values are used for the GWPS calculation and tool
monitoring of the minimum wheel radius ($TC_TPG3).
$TC_TPG9 = 3 Length 1 (geometry + wear + base, depending on tool type)
$TC_TPG9 = 4 Length 2 (geometry + wear + base, depending on tool type)
$TC_TPG9 = 5 Length 3 (geometry + wear + base, depending on tool type)
$TC_TPG9 = 6 Radius
