TOOL AND MAGAZINE MANAGEMENT.
(REF: 1402)
Ground tools.
A ground tool is a tool that is not stored in any magazine and is loaded manually when
requested. Ground tools are also defined in the tool table, but they are not associated with
any magazine position.
Ground tool loading and unloading is global to the system; it is not associated with any
particular magazine or channel.
Tool manager.
The CNC has a tool magazine management that knows at all times the location of each tool.
When requesting a tool change or tool search, the tool manager "tells" the PLC the operations
to be carried out.
• Take a tool from the magazine and insert it in the spindle.
• Leave the tool of the spindle in the magazine and take another one.
• Leave the spindle tool on the ground.
•Etc.
Depending on the type of magazine and the operation requested, several actions may be
needed sometimes. For example, in some magazines, to take a tool from the spindle to the
main magazine, the tool must be carried from the spindle to the changer arm and then from
the changer arm to the magazine.
It is up to the PLC to control those movements. It must inform the manager about the actions
carried out so it updates its information.
For the communication between the tool manager and the PLC, each channel and magazine
has its own group of marks and registers. See "7.3 Communication between manager and
PLC." on page 346.
Subroutines associated with the tool change.
There are two subroutines associated with the tool change.
Subroutines associated with the tool.
The subroutine associated with the tool is executed automatically every time a T function
(tool selection) is executed.
There is one subroutine in each channel.
Subroutines associated with the M06 function.
The M06 function executes the tool change. The CNC will manage the tool change and
update the table for the tool magazine.
It is recommended to set this function in the "M" function table so it executes the subroutine
for the tool changer installed on the machine.
This subroutine is common to the whole system.
Within both subroutines, the "modal" condition of the canned cycles no longer has any influence. This
characteristic is restored when the execution of the subroutine ends.
