4.2  Tool Data
T-Codes, and Tool Activation
To activate a tool, program a T-Code followed by the tool number. The 
tool number corresponds to the row number in the Tool Table.  A 
program tool call example starts with a “T”, followed by the tool 
number, e.g. “T1”.
Activating Offsets via the Program
In a program, T1 (by itself) calls the Tool Table diameter and length 
offsets for the specified tool. T1 with D, R, and L address words 
programs a temporary diameter/radius and length offset independent 
of the Tool Table. The entered D (diameter) or R (radius) and L 
(tool-length) offsets remain active until you cancel the active tool.
The diameter offset takes effect when you program Left (G41) or Right 
(G42). All dimensions are in reference to the work surface.
T1 Format
Description
T1
Activates Tool #1 diameter offset listed 
in the Tool Table.
T1 D.5000 L-1.2500
Applies a diameter offset of .5000 and 
length offset of -1.2500 to the active 
tool.
T1 R.2500 L-1.2500
Applies a tool radius value of .2500 and 
length offset of -1.2500 to the active 
tool.
If you use T1 to activate a tool later in the program, the 
Tool Table offsets for Tool #1 are used (not the values 
programmed via T1 Dn/Rn Ln). 
It is recommended that you use the Tool Table to avoid 
confusion or possible entry errors on the offsets.
