Display MD 9672 $MM_CMM_FIXED_TOOL_PLACE determines whether all
tools have a fixed or variable location coding.
S
Fixed location coding (MD 9672, value 1) means that the tool is permanently
assigned to a magazine location. This concept can be used for machines
with disk–type magazine.
S
For variable location coding (MD 9672, value 0), a tool with a tool number or
tool name can be returned to a different magazine location from its original
one. This variant can be used for machines with chain magazine.
Individual tools can be set to fixed location coding on the operator interface
(tool wear).
Magazine locations can be blocked, e.g. for oversized tools occupying adjacent
magazine locations.
The tool management system includes a tool monitoring function that monitors
based on cutting edges either by tool life, tool loading operations or wear. Re-
placement tools (sister tools) are distinguished by their Duplo number (DP).
The tool monitoring can be deactivated via the display MD 9652
$MM_CMM_TOOL_LIFE_CONTROL.
The wear monitoring is activated via the display MD 18080, bit 5.
Tool management without the load/unload softkey can be set by means of value 2
in display MD 9651 $MM_CMM_TOOL_MANAGEMENT.
Tool management with the load/unload softkey can be set by means of value 4
in display MD 9651 $MM_CMM_TOOL_MANAGEMENT.
Loading brings the tool to its magazine location.
Unloading removes the tool from the magazine.
Tools can be sorted in the tool list and the tool wear list according to
magazine location, name, type, and tool number.
Manual tools are tools that are stored in the tool list but not in the magazine.
These tools must be attached/detached manually to/from the spindle.
