2.8 “T” TOOL SELECTION 
Code T (Tool) defines the tool corrector and the position of the turret to be activated for machining. The 
tool corrector contains information that identifies the characteristics (length, direction, radius etc.) of the 
tool. When programming, the tool setting is always composed of 3 or 4 digits. The first number, or first 
pair of numbers, defines the position of the tool in the turret; this number is therefore usually between 1 
and 12. 
The second pair of numbers, always composed of two digits, identifies the corrector matched to the tool. 
The control memory usually has available 32 tool correctors; therefore the programmer has to select the 
corrector to match to each individual tool. 
For simpler operation it is suggested to match a tool number to the same corrector number. 
Example: 
N1 T101 
N2 ………. 
N3 ………. 
N4 ………. 
N5 ………. 
N6 ………. 
N7 T404 
N8 ………. 
N9 ………. 
N10 ………. 
N11 ………. 
Under certain circumstances it is possible to match a tool with a different corrector, for example to move 
the position of a tool in the turret without having to reset it again. 
Example: 
N4 T121    ; Tool selection T1 with corrector 21 
N5 ………. 
N6 ………. 
N7 ………. 
N8 ……….
