TOOL AND MAGAZINE MANAGEMENT.
(REF: 1402)
Turret type magazine.
7.7 Turret type magazine.
It is a typical magazine for lathes. To make the change, the magazine rotates until it places
the new tool in the work position. The tool cannot be changed while the part is being
machined.
Usually, in this type of magazine, the communication between the manager and the PLC is
configured so it is carried out in a single stage, with the execution of the T function.
When selecting a tool, the subroutine associated with the T executes the M06 function (tool
change), machining stops and the tool manager sends to the PLC the code for the operation
to be carried out.
1 When the CNC executes the T function, it lets the tool manager know about it and calls
the associated subroutine. The M06 function must be programmed inside that subroutine
so the CNC "tells" the tool manager to start making the tool change.
2 The tool manager sends a command to the PLC to select the next tool in the magazine.
3 The subroutine associated with the T function executes the M06 function. The M06
subroutine can also have an associated subroutine. If a subroutine associated with the
M06 function is defined, the M06 function must also be programmed inside that
subroutine so the CNC "tells" the tool manager to start making the tool change.
4 The tool manager sends a command to the PLC to make the change.
5 The CNC waits for the tool manager to complete the operation before continuing with the
execution of the program.
The management of the tool change should be included in the subroutine associated with
the M06 and leave the control of the external devices up to the PLC. Use the auxiliary
functions to govern the various devices (magazine rotation, magazine movement, tool
changer arm, etc.) from the M06 subroutine.
Ground tools in a turret type magazine.
This magazine offers the possibility of working with ground tools. If there is a tool in the work
position and another one is requested that is not in the turret, the CNC considers it to be a
ground tool.
The maneuver for loading/unloading a tool in the spindle (in the work position) either directly
or going through the spindle is the same. In the latter case, the variable V.TM.MZMODE must
have the proper value to load or unload.
