Important: When the miscellaneous function lock feature is activated, the
control ignores M, B, S, and T words in the part program with the
exception of M00, M01, M02, M30, M98, and M99. This miscellaneous
function lock feature is activated through the front panel screen (as
described on page 2-11) or by an optional switch installed by your system
installer.
The format for a T word is as follows:
Trrll;
Where: Is:
rr The dresser/wheel radius and orientation offset number. The
radius/orientation offset number is the first two digits of the T word.
See chapter 3 for details on radius/orientation data.
ll The wheel length offset number. The wheel length offset number must
be the last two digits of the T word. See chapter 3 for information on
length offset values.
An offset number selected as zero (for either length or radius/orientation)
selects an offset value of zero and effectively cancels wheel length offsets
and dresser/wheel radius compensation. Dresser/wheel radius
compensation is not canceled when a radius offset number of zero is
programmed (G41 or G42 remain active). In this case, a radius value of
zero is simply used. Dresser/wheel radius compensation must be canceled
by programming a G40.
Important: T words are always right-justified. This means that
programming a two-digit T word would only enter a wheel length offset
value and not specify a radius/orientation offset number. Table 10.G gives
examples of T words and the resulting offset numbers activated.
