Letter Format Parameters
Chapter 17
17-22
The T-word letter format parameter is covered in T: Tool Number Integer
Format on page 17-22.
Function
This parameter specifies the integer format of a T-word that is used to
program a tool number. This parameter specifies the maximum number of
digits that are permitted to the left of the decimal point in the T-word
format. The number of digits to the right of the decimal point will always
be zero since this parameter has an integer format.
For lathe controls, this T-word is used to call a tool number, wear offset
number, and geometry offset number. For mill controls, this T-word is
used to call a tool number only. For grinder controls, this T-word is used to
call radius/orientation and length offset numbers.
