TOOL MANAGEMENT FUNCTION FOR OVERSIZE TOOLS 

 

Overview 

Tool management function for oversize tools is added to the tool 
management function. 
The figure of an oversize tool can be defined freely, and the figure of 
each oversize tool is registered.    When an oversize tool is stored in a 
cartridge, interference with tools stored in other pots is considered.  
This function is usable with cartridges of chain type and matrix type. 
 

Format 

By G10 data input, an oversize tool number can be set in the tool 
management data.    Moreover, tool figure data can be set.

TOOL LIFE MANAGEMENT 

 

Tools are classified into several groups, and a tool life (use count or 
use duration) is specified for each group in advance.  Each time a 
tool is used, its life is counted, and when the tool life expires, a new 
tool that is sequenced next within the same group is selected 
automatically.    With this function, the tool life can be managed while 
machining is being performed continuously.  Data for tool life 
management consists of tool group numbers, tool life values, tool 
numbers, and codes for specifying a tool offset value.  These data 
items are registered in the CNC.

M

 

A group is selected by a T code, and tool life counting is started by the 
M06 command. 

 

T

 

The T series has two tool change types (the turret type and the ATC 
type).    The turret type uses only a T code to select a group, specify a 
tool offset value, and start tool life counting, whereas the ATC type, 
like the M series, uses a T code to select a group and the M06 
command to start tool life counting.    With the ATC type, only a D 
code is used for specifying a tool offset value.    The tool change type 
is selected by bit 3 (TCT) of parameter No. 5040. 

 

 CAUTION 

      This function cannot be used if bit 1 (LGN) of 

parameter No. 5002 is set to 1 to use the same 
number as the tool selection number to specify a 
geometric offset number.

  - Life management B function 

If the tool life management B function is enabled, the maximum tool 
life value can be extended, and the tool life expiration prior notice 
signal can be output to post tool life expiration in advance when the 
remaining life (the life value minus the life counter value) has reached 
the remaining life setting.    The remaining life setting is registered as 
tool life management data in the CNC in advance. 
The tool life management B function is enabled by setting bit 4 (LFB) 
of parameter No. 6805 to 1. 
 

M

 

If the tool life management B function is enabled, the function for 
selecting a tool group by an arbitrary group number can be used. 

 

T

 

The tool life management B function can be used.  However, the 
function for selecting a tool group by an arbitrary group number can 
be used only if the tool change type is the ATC type (bit 3 (TCT) of 
parameter No. 5040 = 1). 
 

  - Maximum number of tool life management groups and multipath system 

Up to 256 tool life management groups can be used in the entire CNC 
system. 
For each path, set a maximum number of groups to be used in 
parameter No. 6813. 
The maximum number of groups must be a multiple of the minimum 
number of groups (eight groups).    If the maximum number of groups 
is 0, the tool life management function is disabled. 
The total number of groups in the entire CNC system can be expanded 
to 1024 groups by using an option for additional tool life management 
groups.

      Re-setting this parameter results in the tool life 

management data file being cleared at power-on.   
Once the parameter is re-set, register tool life 
management data for each path again.

Suppose that, of the total groups in the system (256 groups), 128 groups are

10.5.1 

Tool Life Management Data 

 
Tool life management data consists of tool group numbers, tool 
numbers, codes for specifying a tool offset value, tool life values, 
arbitrary group numbers, and remaining life settings. 
Whether to use arbitrary group numbers and remaining life settings 
can be specified by setting bit 5 (TGN) and bit 3 (GRP) of parameter 
No. 6802. 

Explanation 
  - Tool group number 

Up to 256 tool life management groups can be used in the entire CNC 
system. 
In parameter No. 6813, set a maximum number of groups to be used.   
With the set maximum number of groups, up to four tools can be 
registered per group.    The combination of the maximum number of 
registrable groups and the maximum number of tools can be changed 
by setting bit 0 (GS1) and bit 1 (GS2) of parameter No. 6800 as 
follows.

 CAUTION 

      After changing the setting of bit 0 (GS1) and bit 1 

(GS2) of parameter No. 6800, re-register tool life 
management data by issuing the G10L3 
(registration after deletion of data for all groups). 
Otherwise, the newly set combination does not 
become valid. 

 

NOTE 

      The total number of groups in the entire CNC system 

can be expanded to up to 1024 groups, using an 
option for additional tool life management groups. 

 

  - Tool number 

A tool number is specified with a T code.    A number consisting of up 
to eight digits (99999999) can be specified. 

 

NOTE 

      The maximum number of digits usable in the T 

code is specified in parameter No. 3032.

    - Codes for specifying a tool offset value 

 

M

 

Codes for specifying a tool offset value include an H code (for tool 
length offset) and a D code (for cutter compensation).    Numbers up 
to 999 (up to three digits long) can be registered as codes for 
specifying tool offset values.  However, the number of registered 
codes must not exceed the number of tool offsets the CNC can use. 

NOTE 

      If codes for specifying tool offset values are not 

used, the registration of these codes can be 
omitted. 

 

T

 

If the tool change type is the turret type (bit 3 (TCT) of parameter No. 
5040 = 0), neither the H code nor D code is used to specify a tool 
offset value.    The T code includes a compensation code.    If the tool 
change type is the ATC type (bit 3 (TCT) of parameter No. 5040 = 1), 
only the D code is used. 

  - Tool life value 

A tool life value can be registered in terms of use duration or use 
count.    The maximum value is as follows: 
Up to 4300 minutes can be registered if duration specification is 
selected, or up to 65535 times can be registered if use count 
specification is selected. 
When the tool life management B function is enabled, up to 100000 
minutes (or 60000 minutes if the life is counted every 0.1 second) can 
be registered if duration specification is selected, or up to 99999999 
times can be registered if use count specification is selected. 

  - Arbitrary group number 

 

M

 

If a function for allowing specification of arbitrary group numbers is 
used (bit 5 (TGN) of parameter No. 6802 = 1), an arbitrary group 
number can be specified with a T code to select a tool life 
management group. 
An arbitrary group number ranging from 1 to 99999999 can be 
specified. 
 

T

 

Arbitrary group numbers can be used only if the tool change type is 
the ATC type (bit 3 (TCT) of parameter No. 5040 = 1).

  - Remaining life setting 

Bit 3 (GRP) of parameter No. 6802 is used to specify which value, a 
value set for each group or a parameter-set value (parameters No. 
6844 and 6845), is to be used as the remaining life setting until a new 
tool is selected. 
If a value set for each group is used (bit 3 (GRP) of parameter No. 
6802 = 1), the value is registered as tool life management data. 
A value ranging from 1 to 100000 minutes (or 60000 minutes if the 
life is counted every 0.1 second) can be specified if duration 
specification is selected, or a value up to 99999999 times can be 
specified if use count specification is selected.
