Wheel length offsets let the programmer write a part program with respect
to the same fixed point on the grinder regardless of the wheel being used.
This fixed point (called the gauge point) is determined by your system
installer. For the purpose of documentation, this manual assumes that the
gauge point is a fixed point on the centerline of the grinding wheel. See
your system installer’s documentation for details on the location of the
gauge point on your system.
This section describes how to enter the length values that are called later
when the corresponding length offset is activated. Typically wheel length
offsets are activated with a T word as described in chapter 13.
The control stores wheel length offsets in a table called the wheel
geometry table. This table stores wheel length offset values under offset
numbers. When you select a certain wheel offset number with a T word in
the part program, the control references this table and looks up the
associated length offset values stored for that offset number. For details on
how and when the length offset is activated, see chapter 13.
