TOOL AND MAGAZINE
MANAGEMENT.
To properly configure the tool magazines and the tool change, you must:
• Set the machine parameters.
• Set the tool table and the tool magazine table.
• Write the PLC program.
• Program the subroutine associated with the tool and with the M06 function.
The machine parameters define the number of tool magazines available and their
characteristics. Up to four magazines may be used and each may be of a different type. See
"7.1 Types of tool magazine." on page 343.
When creating the PLC program and the subroutine associated with the tool and with the
M06 function, you must bear in mind the number of magazines and channels available. For
the communication between the tool manager and the PLC, each channel and each
magazine has its own group of marks and registers.
The PLC maneuver will be different depending on the type of tool magazine. Later sections
of this chapter show an example for each type of magazine.
About the magazines.
The CNC can have up to four magazines and each may be of a different type. Each magazine
has its own configuration parameters.
The number of magazines is independent from the number of spindles and channels
available. A magazine is not associated with any particular channel or spindle; i.e. a
magazine may be shared by several channels and a channel can request tools from different
magazines.
All the magazines can carry out tool changes simultaneously. However, one magazine can
only be involved in a tool change process. If from one channel, one wishes to pick up or leave
a tool in a magazine already involved in a tool change, the tool manager will wait for the tool
change to be done before attending to the new request.
Two magazines may be involved in a tool change. The magazine receiving the tool and the
magazine from where the new tool is picked up may be different.
About the tools.
Each tool is identified by its number, that is unique for the whole system; it cannot be repeated
in different magazines nor in ground tools.
The list of available tools is saved in the tool table, the only one for the whole system. This
table indicates the position and the magazine where each tool is located, whether it is a
ground tool or the tool is active in a channel.
The tools are always stored in the same magazine. When doing a tool change, it is always
stored in the magazine from which it was picked up.
The access to the magazine depends on the mechanical configuration of the machine; in other words,
to the physical possibility of the machine to access the magazines.
