Angled-wheel grinders have the same integrand letter for the wheel axis
(W) and the virtual axis (X). Refer to your system installers
documentation to determine the integrand name for the X and W axes.
It is necessary to tell the control the angle of the wheel axis. This angle is
required to perform calculations that determine the wheel axis position (W)
based on the programmed control positions for the virtual axis X. There
are three methods to specify this angle. They are:
This entry method: Has this configuration:
Fixed Angle the system installer has set the angle of the wheel axis in AMP. The
angle of the wheel axis is rigid and can not be adjusted by the
operator.
Rotary Axis the angle of the wheel axis is determined by the position of a rotary
axis. Typically this rotary axis changes the wheel angle. When angle
wheel mode is entered, the position of the rotary axis is recorded and
used as the wheel angle. The system installer determines this rotary
axis in AMP.
PAL Selected the system installers PAL program enters the angle of the wheel axis.
This method can require you to enter the angle of the wheel axis, or
some external input to PAL can determine the angle. Refer to your
system installers documentation for details.
Refer to your system installers documentation for details on which of these
methods are used on your system.
Regardless of the method used, the angle of the wheel axis must remain
constant once angle wheel mode is entered (G16.3 or G16.4). You can not
change the entered value of the angled wheel axis in angled wheel mode.
Any rotary axis or PAL interface that determines the wheel axis angle must
be disabled in angled wheel mode (except for homing).
