TOOL MANAGEMENT FUNCTION

11.3.1

Tool Management Function

Overview

The tool management function totally manages tool information including information about tool offset
and tool life.

Explanation

A tool type number is specified with a T code. The tool type number is any number the user can define
freely. With tool type numbers, tools can be grouped by various conditions such as life, compensation
value, and cutting conditions. When each type is assumed to have a single tool, tool type numbers are
equivalent to unique tool numbers.
For each tool, an information storage area is prepared in the CNC (SRAM). This area contains
information such as a tool type number, tool life, tool status (such as a breakage condition), tool
compensation number (H, D, G, or W), spindle speed (S), cutting feedrate (F), and freely-definable
customize data. Such data is called tool management data.
A cartridge management table that links cartridge information and tool management data is provided so
that the CNC can manage the cartridges of the machine and tool change operations. In addition, areas for
managing the tools in the spindle and tool standby positions are prepared.
When a tool type number is specified using a T code command, a tool that has the tool type number and
the shortest life is searched for, and the cartridge number and pot number of the location where the tool is
stored are output to the PMC. Then, a tool change operation using the cartridge number and pot number is
enabled by the PMC ladder sequence.
Tool information in the CNC is managed by the tool management data and cartridge management table
(including the spindle management table and standby position table).

Tool management data

As tool management data, information about a tool is registered for each data number.

Cartridge management table

The storage status of tools in cartridges is managed with the cartridge management table.
-

Multiple cartridge numbers can be defined. (Numbers from 1 to 8, up to eight cartridges)

The maximum number of pots for all cartridges is 64, 240, or 1000, which depends on whether a
tool management data option is selected.

Cartridge numbers and pot numbers can be assigned freely within cartridge management data by
parameter setting (described later).

The tool management data number adjacent to a pot number is linked with tool data defined in the
tool management table. Therefore, the tool attached to the pot is indicated.

Zero set as a data number indicates that no tool is attached.

The cartridge management table can be read from and written to through the PMC window and
FOCAS2

The spindle management table and standby position table are provided to indicate special cartridge
positions.
-

Spindle positions and standby positions, regarded as special cartridge positions, have fixed cartridge
numbers 11 to 14 (the positions of the first to fourth spindles) and 21 to 24 (the first to fourth
standby positions).

With the PMC window, the spindle position table and standby position table can be read from and
written to.

Tool life counting is performed only for the tools at the spindle positions.

Multi-path system

The tool management data and cartridge management table are common data among the paths. The
spindle management table and standby position table, however, are treated as independent data for each
path.
When the spindle table or standby position table is specified as a cartridge from the PMC window,
specify the Table 11.3.1 (a), in which the path number is set in the hundred’s place:

Tool life management and tool change

The CNC performs tool life management, regarding tools having the same tool type number as a group.
When a tool type number (T code) is specified by an NC program, the tool management data registered in
the CNC is searched to find a tool having the shortest life among the tools with the same tool type
number.
The cartridge number and pot number corresponding to the searched tool are output as a T code signal to
the PMC. Based on the output cartridge number and pot number, the PMC performs preparation for a tool
change (to the next tool). A different tool can also be selected on the PMC side.
The CNC performs tool life counting for each tool that is at a spindle position in the spindle management
table.

11. TOOL FUNCTIONS

When the lives of all tools having the tool type number specified by the T code have expired, alarm
PS5317, “ALL TOOL LIFE IS OVER” is issued. If there is a tool in the spindle position or standby
position, that tool is selected to continue machining.
As the T code signal, a specified tool type number instead of the cartridge number and pot number can
also be output directly by parameter setting.
There are two types of tool life management counting methods: counting the number of use times and
counting cutting time. One of the counting methods is set in tool information of tool management data.

Other major specifications related to tool life management are as follows:
Tool type number (T code)

: Up to 8 digits (1 to 99,999,999)

Maximum tool life value

: 99,999,999 times when the number of use times is specified

: 999 hours 59 minutes 59 seconds when time is specified

Life count interval when time is specified : 1 second
Tool life management count restart M code : Enabled
Tool life count override

: Enabled

Selecting a tool having a tool type number and shortest life

The following example explains how a tool having a tool type number specified by a T code is selected:

N10 T11111111 ;

(1) Among tools whose tool type number is 11111111, a tool having the shortest life is searched for(*1).

Since the tool with the shortest life is assigned tool management data number 1, the numbers of the
cartridge and pot holding this tool are obtained.

The following tools are not searched:
-

Tools not assigned to any cartridge

Tools whose tool life status is 0 (Life management is not performed.)(*2)

Tools whose tool life status is 3 (Life has expired.)

Tools whose tool life status is 4 (tool breakage)

Tools whose tool information bit 0 invalidates the tool management data

Tool being edited on the tool management screen

Tools whose tool life counter indicates the maximum tool life value.

If multiple tools have the same life value, a search is made according to the following priority:

High

Spindle position

Standby position

Low

Cartridge

If a cartridge contains tools having the same life value, the tool with the smaller tool management
number takes priority.

NOTE

1 If bit 6 (SWC) of parameter No. 13203 is 1, a tool whose customize data with a

customize data number specified in parameter No. 13260 is smallest is searched
for instead of a tool with the shortest life.

2 Even when the tool life status of a tool shows that life management is not

performed (= 0), the tool is targeted for a search operation if bit 4 (SEN) of its
tool information is set to 1. In this case, the remaining life is not checked. The
cartridge number and pot number of the tool found first are output as the search
result.

(2) Since the tool with tool management data number 1 is stored at cartridge number 1 and pot number

30, binary value 0001 is output at PMC addresses <Fn026 to Fn027>, and binary value 0030 is
output at <Fn028 to Fn029>.

(3) On the machine side, the tool searched for is moved to the standby position.
(4) By using the PMC window (function code 329), the tool whose cartridge number 1 and pot number

30 in the cartridge management table is moved to the standby position (cartridge number 21).
