was being carried out (all moves with the exception of G00) as the ma-
chining time.
However, if the tool wear factor is entered in mm/cycle or inch/cycle, the
tool management system uses one cycle as the machining time. Thus,
the compensation value for tool length corresponds to the tool wear fac-
tor.
The tool management system automatically updates the machining time
and, thus, the compensation value for length wear.
•
upon a transition to a different edge
•
when an edge is called again
•
when the tool is placed back in the magazine (tool storage = magazine)
•
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 storage
present).
Radius wear compensation is activated when tool path compensation is
activated via G41 or G42. The compensation value used to adjust for tool
radius wear is calculated in the tool management system by multiplying
the duration of tool machining time by the radius wear factor. If the radius
wear factor is entered in mm/min or inch/min, the tool management sys-
tem uses the total time in which the tool was active while working motion
was being carried out (all moves with the exception of G00) as the ma-
chining time.
However, if the radius wear factor is entered in mm/cycle or inch/cycle,
the tool management system uses one cycle as the machining time.
Thus, the compensation value for tool radius corresponds to the radius
wear factor.
The tool management system automatically updates the machining time
and, thus, the compensation value for radius wear.

User data 1–5 in the basic tool data allow any desired user-specific data
to be included for each edge.
When the desired name is entered in the system parameters, the user
data are placed in each edge set and tool list and are displayed in the
active tool list (see also Description of Parameters).
The user data, as well as the other data, can be prepared in the tool list.
Typical example of user data in the edge data are:
•
Surface speed
•
Feed per tooth
•
Spindle speed
•
Machining feedrate
•
Temporary measurement buffer
•
Average value
•
Empirical value
The user data 6-10 for edges enable the machine manufacturer to define
additional data elements in the tool data record by specifying a corre-
sponding designation. Numbers with up to 8 significant digits (32-bit val-
ues without exponent) can be stored in the user data 6-10 for edges (of
the DINT type with 32-bit values without exponent).
