Angled-Wheel Grinding
Chapter 14
14-3
You can home a rotary axis that determines the wheel axis angle while in
one of the angled wheel modes. This homing res ults in angled wheel mode
being re-initialized using the angle of the wheel immediatly after it has
been homed.
Manually Measuring your Wheel A xis Angle
In some cases the system installer may have written PAL to require that the
wheel axis angle be entered into PAL manually. This is usually done
through a customized PAL display page on the control or through a switch
on the MTB panel. When this is the case you must measure the angle of
the wheel axis. Figure 14.2 shows how the wheel axis angle is measured.
θ in the figure below is a positive angle.

Valid wheel axis angles are ultimately determined by the system installer
under the following constraints:
- The wheel axis angle can not be larger then 180°
- Wheel angles that approach 90° are invalid
- Wheel angles are always positive angles
- Angles can be measured to the resolution of the axis if a rotary axis
determines the angle
- Angles can be measured to a maximum resolution of two decimal
places if the angle is determined through PAL.
