T parameter and tool change
The T parameter is devoted to the tool change, together with the M6 function. The digits following the T letter
indicate the tool number to recall.
The T parameter has the purpose to prepare the machine for the tool changing (i.e. to prepare the axes of tool
magazine for the change), while the function M6 starts the actual change.
For further details, please consult the machine tool builder.
For example, to set the tool number 5, the following instruction is programmed:
T5M6
Warning: At the moment of tool change all parameters present in the tool table for the desired tool are
recalled and assigned.
The values for tool length (LX and LZ) and radius (R) are assigned, together with every other parameter
stored in the table.
Note
: The tool table is stored in the NC CMOS memory.
Depending on the process the tool tables belong, the files are the following:
Process:
0
1
2
3
4
5
Tool
table: 127 124 121 118 115 112
In the machines with a single process, the file containing the tool descriptions is the file
127
(the file related to
process 0).
The syntax of a tool table file is as follows:
T1P127
:TL
T1#1R0.4LX-121,230LZ-74.21
T2#2LX-124,354LZ-112.345R0(TRUNCATING TOOL)
…
The file starts with the tool actually mounted on the spindle. In the above example, it is the tool number 1,
contained in the file number 127.
The “:TL” label specifies the start of the section describing the tools.
In the following lines, the descriptions of the various tool are stored.
- The “
T
” parameter indicates the tool number
- The “#” parameter indicates the position of the tool in the tool magazine.
- The various parameters describing the tool are inserted in the line through the parameter name and
its numeric value.
- The line may have a comment inserted between parenthesis.
In the example:
The tool T1 is positioned at place #1, has a length LX-121.23, length LZ-74.21 and radius R0.4
