Tool Change With Active Tool Management; Tool Change With Active Tool Management With The Function T=Location - Siemens SINUMERIK 840D sl Programming Manual

Fundamentals
2.4 Tool change
Programming of the tool change when tool management is active / not active
Programming of the tool change when tool management is active / not active differs from
programming of the tool change with deactivated tool management. Both variants are therefore
described:
→ Tool change with active tool management (Page 60)
→ Tool change with deactivated tool management (Page 64)
Programming of the working plane
The appropriate machining plane (Page 33) has to be programmed for the tool change (initial
state: G18). This ensures that the tool length compensation is assigned to the correct axis.
Activation of the tool offset
The tool change activates the tool offset values stored under a D number (Page 80).

Tool change with active tool management

Tool management
The "Tool management" function ensures that at any given time the correct tool is in the correct
location and that the data assigned to the tool are up to date. It also allows fast tool changes and
avoids both scrap by monitoring the tool service life and machine downtimes by considering
replacement tools.
Tool name
On a machine tool with active tool management, the tools must be assigned a name and
number for clear identification (e.g. "Drill", "3").
The tool can then be called with the tool name, e.g.
T="Drill"
Note
The tool name may not contain any special characters.
