The edge status bits provide information on the status of a given edge.
The following table shows the edge status bits used in the tool list.
Group Status Bits Symbol Remark
Wear status
Edge done d Value cannot be changed
Warning limit reached w Value cannot be changed
User edge status 1
User edge status bit 1 as desired Value can be changed
User edge status 2
User edge status bit 2 as desired Value can be changed
User edge status 3
User edge status bit 3 as desired Value can be changed
User edge status 4
User edge status bit 4 as desired Value can be changed
Up to four different user-specific status bits can be assigned to each
edge. They can be preset in the tool list.
The two edge status bits:
•
„Edge done" (d) and
•
„warning limit reached" (w)
cannot be modified directly in the tool list. However, they can be reset with
the aid of a reset function (see Tool Data Management) in the description
of the user interface.
The remaining tool life in percent indicates the wear condition of a tool
without taking the tool/workpiece material combination or process data
into account.
remaining tool life [%] =
remaining tool life [min] or [cycles]
maximum tool life [min] or [cycles]
100 [%]
∗
A new or reground tool has a remaining tool life in percent of 100%, while
a completely worn tool has a remaining tool life in percent of 0%. The tool
management system manages and monitors the wear status of the tools
based on the remaining tool life in percent and ignoring the tool/workpiece
material combinations of the current machining operations.
The remaining tool life in percent is updated:
•
during the automatic tool check
•
upon a transition to a different edge
•
when an edge is called again
•
when the tool is placed back in the magazine (tool storage = maga-
zine) or
•
when the tool is rotated out of the machining position (tool storage =
turret)
•
when a tool is canceled using TO (tool storage = turret or no tool stor-
age present).
The remaining tool life in percent is calculated using the following calcula-
tion specifications:
% rem. tool life = % rem. tool life -
utilization time [min] or [cycles]
max. tool life [min] or [cycles]
100 %
after before
∗
At the time of each update the tool management system checks the re-
maining tool life and sets the interface signal 'PxxS.MGTWO' for the SPS
if the remaining tool life of a tool indicates that the tool is fully worn and
that a useable spare tool is not present.
