Entire Wheel Radius
The control can compensate for the radius of the entire grinding wheel. To
do so, the radius of the wheel must be entered in the radius table for
dresser/wheel radius compensation. This method of compensation does
not require any X-length offset to be activated. Only a Z-length offset
needs to be activated with the X offset being compensated for by the wheel
radius. For more information on activating an offset for dresser/wheel
radius compensation, see chapter 15.
Important: An additional radius offset number (33) is available only to
the in-process dresser feature. This radius value is the entire wheel radius
and changes as the wheel radius diminishes each time it is dressed. See
chapter 21 for details on the in-process dresser feature.
To assign a value to radius offset number 33, use either:
the dresser data screen “Current Wheel Diameter” found on page 21-9.
directly assign a value to paramacro parameter #5508 (see page 20-39)
