3-2 Warming-up Operation of Spindle
3-2-1 Warming-up at the Time of Starting Daily Operation
Caution
It is necessary to keep the bearing lubrication in a good condition for getting the normal
spindle revolution. If the spindle is suddenly rotated at a high speed without warmingup, there is a danger of the oil film being cut and the bearing is burnt stuck. To have
the spindle operated correctly in full capacity, warming up operation is necessary of
which the following should always be practiced practice.
Warming-up before starting daily operation (30 minutes)
[1] 30% of maximum spindle revolution (10 minutes)
↓
[2] 50% of maximum spindle revolution (10 minutes)
↓
[3] 80% of maximum spindle revolution (10 minutes)
Practice warming in the order of [1] , [2] , [3] .
3-2-2 Warming-up When the Machine Was Not Operated for More Than One Week or
Longer
Caution
In case of starting the spindle of oil air lubrication, after it has not been used for more
than one week, warming-up must be practiced taking a longer time than usual, as oiling

(2) Of the push button switches for the axis desiring “Zero return”, press the one with the origin
mark ( ).
(3) By the specified speed of the rapid feed override, the axis returns to the zero point in the
rapid feed speed, and stops at zero point. Then, the zero point position confirmation lamp
of the axis is lit on.
(4) When the lamp lights up, release the switch.
Even when unhanded during decelerated speed movement, the axis stops after zero point
is generated.
The above operations will complete zero return.
Caution
1. Make zero return operations for each axis one by one.
2. When the axis for which zero return is intended is already located close to the zero
point, move axis once to the opposite side of the zero point by about 50mm then
move it again to the direction of the designated zero return point.

8-7 Alteration of Word (Expanded Tape Editing)
At the program screen, search a designated word to be altered in the program and rewrite it to a
word to be altered.
There are following two methods for alteration of word.
1) Search one word each and alter if after confirmation.
2) Alter words collectively (or after words continuously with display an altering condition).
The words to be altered collectively are maximum 400,000 words.
A method to search a word is the same as the word search, words combined one character of
alphabet (or “#” mark) and numerals becomes the number search as words showing the numeral
value and recognize it with or without a decimal point.
For example, of changing “X.1” to “X.5”, a row of characters such as “X0.1”, “X0.100”, “X00.10”,
“X.1” or “X.100” which coincide with “X.1” as numeral value, become the object of alteration and
change all to “X.5”.
Also, if adding a “?” mark on the word to be changed as “X.1?” such as changing “X.1?” to “X.5”,
a row of characters “X.1” becomes the object of alteration, then “X1” becomes “X.5” and “X.100”
becomes “X.500”, however, “X.01”, “X0.100” and “X00.10” does not have the row of character
“X.1” so it does not become an object of alteration.
Outline of operation
Start alteration of word by pressing the F5/WORD CONVT. key.
[1]
INPUT in the order of a word to search and alter then a word to replace it.
If replacing word is blank, it becomes a deletion.
[2] When searching a word one by one, designate a searching direction by the cursor
and press the Y key if found a word to be altered.
[3] For altering a word contained in many places of the file collectively, designate the
searching direction by the function menu. Confirm that such overall alteration is
unmistakable, then press Y key.
Once word alteration starts, it goes on to the beginning or end of the file, depending
on the searching direction. For suspending the alteration,
Press the F5/EXIT key.
In case of the alteration of words collectively as mentioned item [3], alter it except a
row of characters in the comment. To change inside of comment, alter it by the
method [2].

Fig. 1.8 Tool (Compensation)
(Note 1) When writing in a tool diameter, if measurements are repeated several times without
changing the designated offset No., the offset amount is rewritten only when the result
of a later measurement gives a larger value than that of previous one. If the
designation of the offset No. is changed or tool setter button is pressed anew,
however, the first measurement result is written in as the offset amount.
(Note 2) The reference gauge means the contact surface of a reference block. When using a
touch sensor on a table other than a reference block, the reference gauge means its
contact surface.
1 - 79
Page 85
(Note 3) Data of the touch probe used for measurement is set in parameter (No.6252~6255) in
advance. There are two ways of the setting, one is to write in as parameter and the
other is to write in on the tool (compensation) screen. For the latter method, press
F8/SENSOR SET and get the multi-window setting screen (Fig.1.9) on which data
setting can be arranged.
Fig. 1.9 Sensor Setting
Instead of using a touch probe, it is also possible to measure the distance to the reference
gauge by using a tool of known size (called as a reference tool). In this case, set the parameter
(No.6242, 5-bit) as “1” and set the size of the reference tool in advance with parameter
(No.6260~6263).
16-8 Tool Length Measuring Mode, Tool Diameter Measuring Mode
By setting “1” with parameter No.6242 4-bit, the tool length measuring mode and the tool
diameter measuring mode.
In these modes: If tool diameter is measured in the tool length measuring mode, alarm
(No.716) is issued.
If tool length is measured in the tool diameter measuring mode, alarm
(No.716) is issued.
If measurement is made on screen other than tool (compensation) scene,
alarm (No.716) is issued.
This system enables to prevent offset setting error arising from any wrong probe contact.

Caution
(1) Work setter and tool setter are effective in the manual mode.
(2) While the work setter or the tool setter is in operation, when a touch sensor
signal comes on, further axis movement becomes possible only in the opposite
direction, any other axis movement being prohibited.
(3) When a touch sensor signal comes on, buzzer begins to sound and it continues
until the axis is moved out to the opposite direction by a distance equivalent to
the value of the parameter setting (No.6265). While buzzer is sounding,
rewriting of work origin offset amount and tool offset amount does not take place
even when a touch sensor signal comes on.
(4) The automatic rewriting of the work origin offset amount or the tool offset amount
in the work setter and tool setter operations functions on the offset amount on
which the cursor is positioned at the time of the touch sensor signal coming on.
Even when screen then displays other than work coordinate (compensation) or
tool (compensation) scene, the system keeps the last location of the cursor in
memory.
(5) When measuring with the handle, if the following methods are applied to make
the censor touch, they may not keep the axis free (the axis doesn’t move.) Pay
attention.
[1] Turn the handle intermittently by few scales for touching.
[2] To bring the censor near or to keep it away (to turn the handle in + and -

Caution
(6) When making a hole measurement, three measuring points for probe touch
should be selected as mutually distant as possible.
(7) When making measurement, the center of the probe ball correctly positioned
against the measuring face.
(8) When the thermal displacement compensation function is used together with the
work setter function, attention should be paid to the following points.
Parameter No.6242 0-bit should be set as “1”.
Before making measurement, direct the command of ATC (M06Txx) or M code
for effecting the thermal displacement compensation data.

18. Tool Life Management
18-1 T ool Life Management
1. Feature
The tool life management function counts the tool life use values of the tools used in the
machining program according to the life units for each tool.
It compares a counted tool use value with a tool life set value to control a tool life. When
you do not want tool life management in the measuring program, control this function by a
G-code. When the power is turned on or the NC unit is reset, the G131 mode is selected.
G130 ----- Tool life management disabled
G131 ----- Tool life management enabled
2. Functioning
Tool life management carries out the following actions sequentially.
• Selecting a tool for the spindle (when a Txx command in the program is executed)
• Checking the spindle tool status (when M06 in the program is completed)
• Counting the tool life (during machining by the program)
[1] Selecting the tool for the spindle
When a Txx command is executed in the machining program, the tool life
management function selects a tool to be called to the spindle. If the Txx command is
a spare tool command, a defectless tool will be automatically selected out of a spare
tool group.
* If the selected tool is an unused one, a new tool signal is output to the PC.
(During TF)
[2] Checking the spindle tool status
The tool life management function checks the tool status of the tool called to the
spindle by the M06 command in the machining program.
• When the tool is unused → Designates the tool status “USED” or
• When the tool is out of life → Displays a warning, “781 OUT-OF-LIFE TOOL WAS
• When the tool is broken → Displays a warning, “780 BROKEN TOOL WAS
[3] Counting the tool life
When the following requirements are met, the tool life management function counts the
tool life use value of the spindle tool according to the tool life units preset for each tool.
• Under automatic operation in the MEMORY mode
“MONITORED.”
SELECTED.” In the M56 mode, however, the
machine stops due to feedhold.
SELECTED.” The machine stops due to feedhold.
1 - 92
Page 98
• Dry run, Z-axis cancel, and machine lock are not turned on
• In the M53 mode (M54 monitoring function is not stopping)
• In the G131 mode
When a counted use value reaches a preset life value, the tool status for that tool is
designated OUT OF LIFE, but machining continues as it is. When the life set value is
zero, only counting of the life use value is performed and out-of-life judgment is not
made.
* When the tool status is designated OUT OF LIFE and that tool or all the tools in
the same tool group are defective, a tool change signals output to the PC.
3. Life Units
As tool life units, set time, use times, length, and number of holes for each tool. The tool life
is counted as follows according to the life units.
• Time ................ Counts cutting feed time (minutes) during spindle forward rotation.
When the parameter No. 8002 #0 is “1”, it is counted even during spindle
reverse rotation.
• Use times ........ Counts how many times the tool has been called to the spindle (at the
time of M06).
• Length.............. Counts a cutting distance (meters) during spindle forward rotation.
• No. of holes ..... Counts the number of holes machined in a canned cycle for tapping or
drilling. It is counted earlier than actual machining because it is counted
by buffering.
(Note) The data below a minute and meter (seconds and millimeters) are intern ally
counted and memorized.

4. Tool Status
The TOOL screen lists the status of each tool as follows. It is displayed when the machine
specification requires it. Typical specification is mentioned in parentheses, but it is not
always displayed.
USED ..................................... The tool is used.
MONITORED ......................... The tool is used with load monitoring enabled.
OUT OF LIFE ......................... The tool is out of life.
WORN OUT........................... The tool is worn out. (Cutting monitoring)

OVERLOAD ERROR............. An overload error resulted. (Cutting monitoring)
NO-LOAD ERROR ................ A no-load error resulted. (Cutting monitoring)
EXTERNAL ERROR .............. An external error resulted. (Breakage detection, etc.)
18-2 Spare Tool Management
measurement. (Macro measurement, etc.)
(Macro measurement, etc.)
1. Feature
If the Txx command in the machining program is a spare tool command, the spare tool
management function will automatically select a defectless tool out of a preregistered spare
tool group. The tool is selected out of the spare tool group in order of used tool
(MONITORED included), unused tool of higher order registration, and last selected tool if all
the tools are out of life.
2. Functioning
Determine a group number for the tools of identical type which are specified as spare tools
in the program, using an arbitrary number larger than the numerical value in the parameter
no. 8078 (standard value: 1,000), and register it as a call number used to specify a spare
tool in the SPARETOOL screen.
Register the spare tools in the tool group in ORDER 1 onward.
After setting the call number and spare tool number, specify a spare tool in the program.
The spare tool management function automatically selects a defectless tool out of the spare
tool group.
1 - 94
Page 100
3. Specifying the Offset
(1) Tool Offset by Tool Number
If a “tool offset by tool number” option is added to the NC unit for the SEICOS-Σ, tool
offset can be applied by a spindle tool number without taking offset data “H” and “D”
into account, even if the spare tools are used. (You only have to specify an offset
instead of specifying H and D.)
(2) Tool Offset by Optional Block Skip
An offset for the spare tool is specified by informing the NC unit of a spare tool
registration position as an optional block skip position. (For two or more tools, an NC
option is required)
Caution
If the [OPTIONAL BLOCK SKIP] switch on the operation panel is used by an NC
program, machine operation becomes unstable because it is duplicated by offset
designation for the tool life (optional block skip). When using offset designation for the
spare tool, separate the [OPTIONAL BLOCK SKIP] switch on the operation panel from
the program used.
Make a machining program by combining an offset number with a block skip number.
4. Spare Tool Data
Since the tool life set value and life units for the tool group are set under CALL NUMBER, it
is not necessary to set them for each spare tool. The tools registered as spare tools are
displayed less clearly in the TOOLLIFE screen and you cannot set the data for them. Set
the data in the SPARE TOOL screen.
If a tool number is registered in ORDER 1 in setting only the call number (the tool name and
life set value of the call number are zero), the tool name and life data for the ORDER 1 tool
will be set as the data for the call number .
Cutting monitoring is performed based on the data for the first spare tool.
18-3 Premachining Tool Check
1. Feature
At the beginning of the machining program, specify the tools to be used in the subsequent
machining. The premachining tool check function will checks whether all the tools used,
including spare tools, are defectless or not.
If there is even one defective tool, the machine stops, displaying a warning, “782
PREMACHINING TOOL CHECK ERROR.”
2. Functioning
If the tool used for machining is specified (spare tool) between M51 and M59 in the
program, it will be checked if the specified tool is defectless or not. If there is even one
defective tool, the machine stops upon completion of premachining tool check (M59),
displaying “782 PREMACHINING TOOL CHECK ERROR.”
