Angled Wheel Parameters
Chapter 35
35-11
Function
Use this parameter to define the center of rotation for the wheel axis. On a
typical angled-wheel grinder, the wheel axis rotates about its zero point.
Leave this parameter at it’s default value (0) unless your wheel axis rotates
about some other point. This parameter is used regardless of how the
parameter Wheel Axis Source is configured.

All [617]
Always measure the Wheel Position at Rotation Center value from the
machine zero point on the wheel axis. The above figure shows the wheel
axis center of rotation at 7 inches from the machine coordinate system zero
point.
Range
--100000.00000 to 100000.00000 in.
or
--25400000.00000 to 25400000.00000 mm
Notes
This is a global parameter. The value set here applies to all axes.
