20. Tool life time (LIFE TIME)

Input tool life time (maximum possible operating time) using the numeric data keys, and press

the INPUT key.

Note: The NC unit cannot manage the life of that tool if 0 remains set at this item.

21. Tool operating time (CUT TIME)

Input tool operating time (cumulative cutting feed time) in minutes, and press the INPUT key.

- The tool operating time is automatically counted up during actual cutting feed of the tool.

The display of the CUT TIMEitem in the CONTENTScolumn and of the items TNo.and TOOL

in the TOOL LISTcolumn will be reversed in magenta when the tool operating time reaches the

life time specified above.

- The display of the items TNo.and TOOLin the TOOL LISTcolumn will be reversed in yellow

when the tool operating time approaches the life time specified above.

The judgment of the approach to the life time is made according to the setting of the following

parameters:

F82bit 2 (Method of judgment)

= 0: The rate of the operating time to the life time has reached the setting of F77.= 1: The remaining serviceable time has descended to the setting of F77.

F77(Reference value of judgment)

ForF82bit 2 = 0: Critical rate of the operating time to the life time (in %).

ForF82bit 2 = 1: Critical remaining serviceable time (in minutes).

Note 1: This step is to be omitted for a new tool (to leave the default setting 0 as it is for the

CUT TIMEitem).

Note 2: The judgment of tools approaching the expiry of their life is not effectuated if parameter

F77remains set to 0.

22. Tool wear compensation data (WEAR COMP.)

As workpiece machining progresses, increasing wear on the tools may gradually deviate theactual nose positions of the tools from the program-designated dimensions. Set any such errors

in this data item to carry out tool offset.

If tool offset is required following measurement of machined workpieces, tool wear compensation

data must be input.

Tool wear offset data will be automatically corrected by the offset value when a workpiece

measurement unit or a nose measurement unit in a MAZATROL program is executed.

23. Maximal available tool wear compensation data (MAX WEAR)

Set the maximal available tool wear compensation data. When the tool wear compensation data

reaches this data, the tool is regarded to be exhausted.

Setting such data enables spare tools to be indexed automatically.

24. EASY COMP. (easy wear compensation) data

Use the easy wear compensation function when the degree of wear which will progress

according to the particular amount of machining can be estimated from the experience of the

operator beforehand.

Set compensation intervals in LIFEof NUMBER.

Set the compensation amount in the data item EASY COMP.

As machining progresses, data that has thus been set in EASY COMPis added to the WEAR

COMPdata at the designated compensation intervals.


24/54


7-24

Example:

If it can be estimated that machining of 100 workpieces using tool of TNo. 1 causes the tool

to wear by 0.01 in its X-axial direction and 0.013 in its Z-axial direction, then set data as

follows:

EASY COMP X 0.01 Z 0.013

NUMBER LIFE 100 USED 0

Also, suppose that the WEAR COMPat that time has the following data:

WEAR COMP X 0. Z 0.

After 99 workpieces have been machined using this program, the display changes as

follows:

NUMBER LIFE 100 USED 99 The data becomes 99.

After one more workpiece has been machined using this program, the TOOL DATA display

further changes as follows:

WEAR COMP X 0.01 Z 0.013 The easy compensation amount has been added.

NUMBER LIFE 100 USED 0 Since the compensation interval value is 100, thevalue 0, not 100, is displayed after 99.

Note 1: Tool life management in terms of number of machined workpieces and machining time

cannot be used together with easy wear compensation; if easy wear compensation

function is used, only life management in terms of maximum wear can be used.

Note 2: The amount of easy compensation data is not added when no data is set on the MAX

WEARitem.

25. CONS. COMP (constant wear compensation) data

During workpiece measurement in a measurement unit, if a sensor turns on in the

compensation area, the CONS. COMP value of this display will be added to that of the

WEAR COMPdata item. Thus, measurement errors due to swarf are minimized.

In the normal measurement mode (when data is not set in CONS. COMP), if a sensor turns

on in the compensation area, the difference between the target value and the value at which

the sensor has turned on will be added to WEAR COMP.

Example:

Set the CONS. COMP data for the tool for which WORK MES OUTER is applied as

follows:

CONS.COMP X 0.01 Z

Also, suppose that the display at that time has the following data.

WEAR COMP X 0. Z 0.

Assume that the measured diameter of the workpiece falls within the compensation area.

Also, assume that the difference from the target value is 0.013. Since 0.01 has been set in

CONS. COMP, WEAR COMP is incremented by 0.01. Data is therefore displayed as

follows:

WEAR COMP X 0.01 Z 0.

7-1-5 Tool length measurement

The actual length of each tool to be used must be measured for setting data under LENGTH,

LENGTH A or LENGTH B on the TOOL DATA display. Measurement of the tool lengths can be

made with the TEACH method, the manual measurement method or the MDI measurement

method. Here, the operating procedure for tool-length measurement using the [LENGTH

TEACH]function and and the manual tool-length measurement method are described. For theMDI tool-length measurement procedures, see the Operating Manual for machine.

When measuring the tool length of a turning tool using the TOOL EYE or TEACH function, it is

necessary to enter data in the TOOL, PART, CUT DIR., and NOSE-R of tool data

beforehand. Failure to perform this will make it impossible to measure the tool length properly. In

addition, do not modify data of the above four items after measuring the tool length.

1. TEACH methode

A. When the B-axis angle is 0, 90, or 180

The operating procedure is shown below taking as an example the case that the TEACH method

is used when the B-axis is positioned at 90.(1) Mount on the spindle the tool whose length is to be measured.

- Carry out the tool change operation to mount on the spindle the tool which is accomodated

in the magazine pocket. For the operation, see the Operating Manual for machine.

(2) Perform manual axis movements to bring the tool tip into contact with the outer diameter

surface of the reference workpiece.

Example:

7-1-6 Tool setting measurement

Storing data related to the positional relationship between the nose of each turret-mounted tool

and the reference workpiece zero-point into the NC unit is referred to as tool-setting.

The tool-setting data TOOL SET Xand TOOL SET Zrefers to the distance from the tool nose to

the reference workpiece zero-point while the X- and Z-axis stay at the machine zero-point.

The actual distance from the noze of the tool to the reference workpiece zero-point must be

measured for setting TOOL SET data on the TOOL DATA display. Tool setting measurement

can be made with the TEACH method, the manual measurement method or the MDI measure-

ment method. Here, the operating procedure for manual tool-length measurement using the

[LENGTH TEACH] function of the TOOL DATA display is described. For tool measurement in

the MDI mode, see the Operating Manual for the machine.

Once tool-setting data has been input, the tool nose can always be located correctly at the

programmed position simply by setting the distance from the reference workpiece zero-point to

the program zero-point (Z-offset) for each workpiece you are going to machine.

To execute automatic operation, tool-setting data must be input for all tools you are going to use.

1. Setting tool-setting data

Three methods are available for setting tool-setting data:

- Using the TEACH (nose position store) menu function

- Manual nose measurement using a TOOL EYE (TOOL SET MEASURE) (option)

- Using the AUTO INPUT menu function for TOOL SET data

Note 1: The TOOL EYE, however, cannot be used to set tool-setting data for touch sensors.

For further details refer to the description on touch sensor operation.

Note 2: Tool-setting point for each tool (tool nose reference point) is described at the end of this

subsection.Note 3: Use the MDI operation mode to select a tool for which the TOOL SET MEASURE

function is to be applied.

Enter T003000.1, for example, for the tool No. 3 of the application direction .


34/54


7-34

A. Method using the TEACH function

(1) Index the tool for which the tool-setting data must be set (press the tool selector button in

manual operation mode).

First set the TOOL SET X.

(2) Press the cursor key to move the cursor to TOOL SET X.

(3) Bring the tool nose into contact with the O. D. surface (or I. D. surface) of the referenceworkpiece.

- Move each axis under manual operation until the tool nose has touched the workpiece as

The value of TOOL SET Zwill be automatically set.

B. Manual nose measurement using a TOOL EYE (TOOL SET MEASURE)


- The TOOL EYE will move out to the predetermined measuring position.

Note: Be extra careful not to bring the arm of the TOOL EYE into contact with the tool or

workpiece during TOOL EYE OUT/IN operations. If contact is likely to occur, either

move the turret to a safety working zone or remove the workpiece.

(2) Index a tool that requires setting of tool-setting data (take care that no interference occurs).

(3) Move the tool nose close to the sensor of the TOOL EYE.

(4) Press the [TOOL SET MEASURE]menu key (first, set the TOOL SET X).

- The LIST INPUT display mode will be automatically set and the line of the currently

indexed tool will change into a reverse display status.

Example: If tool No. 2 was indexed during procedural step (2) above:

- The cutting feed mode will be automatically selected and the feed rate will be fixed at the

measuring speed specified in parameter K13.

- The value of TOOL SET Xwill be set automatically.

- The reverse status of the line in the procedural step (4) will be cleared.


- Press the axis move button used to move that axis in an opposite direction to that of [2] in

procedural step (5) above.

(Because of an interlock function, the axis cannot be moved even if other axis movebuttons are pressed.)

- The other axes can be moved after the movement of the selected axis has been

temporarily stopped by releasing the axis move button.

(7) Press the [TOOL SET MEASURE]menu key. Then, set the TOOL SET Z.

(8) Bring the tool nose into contact with the sensor located in the Z-axis direction.

The value of TOOL SET Zwill be set automatically.


(10) Return the TOOL EYE to its storage point.

- Press the [MSR UNIT OFF]menu key.

- If, following the above setting operations, tool-setting data is also to be set for other tools,

repeat procedural steps (2) to (9) above.

Note: For drill, tap, or other such tools having a specific diameter, corrections must be made

for the radial data after tool-setting data has been input using the above method.

Example 1: If tool-setting data measurement has been performed for a tool such as that

shown below:

d/2

T3S054

X

Z

: Reference point of the tool nosed: Tool diameter

In the Z-axis direction, the reference point of the tool nose will be measured directly. In the

X-axis direction, however, the position that is offset through d (d/2 2: diameter value) in a

plus direction from the reference point of the tool nose will be measured.

Therefore, if the value of TOOL SET Xwhich has been measured during tool-setting data

measurement is a, then the correct value ofTOOL SET X will be a d.

Example 2: If tool-setting data measurement has been performed for a tool such as that

shown below:

Z

X

d/2

T3S0055

: Reference point of the tool nosed: Tool diameter

In the X-axis direction, the reference point of the tool nose will be measured directly. In the

Z-axis direction, however, the position that is offset through d/2 in a plus direction from the

reference point of the tool nose will be measured.

Therefore, if the value of TOOL SET Zwhich has been measured during tool-setting data

measurement is b, then the correct value of TOOL SET Zwill be b d/2.

If the values of TOOL SET X and TOOL SET Zwhich have been measured during tool-

setting data measurement are a and b, respectively, then correction data for the tool with

a diameter value d can be represented as shown above according to the measuring

direction.

How to correct tool-setting data

Tool-setting data can be more easily corrected by using the INCREMENT INPUT function in

the following order:

1) Place the cursor on the data to be corrected.

2) Press the [INCRMENT INPUT]menu key.

3) Set addition data (d/2, +d/2, d, +d) to the data to be corrected.

Note 1: During manual interruption in the automatic operation mode, the tool-setting data

measurement using a TOOL EYE must not be executed. When such an operation is

executed, the coordinate system cannot be guaranteed for the restarted automatic

operation.

7-38

Note 2: After pressing the [TOOL SET MEASURE] menu key at step (4), check if the required

line of tool data is highlighted correctly. Use the cursor keys as required for the shift of

the highlighting before bringing the tool tip into contact with the sensor.

The highlighting can be shifted by operating the cursor keys.

2. Setting tool wear compensation data

(1) Calculate the tool wear compensation data.

Example: If the measured diameter value of a machined workpiece is 30.24 mm for a

programmed diameter value of 30.00 mm, as shown below:

T3S057

30 30.24

TNo. 1

Machining shapedefinded in the program

Measured value of amachined workpiece

Tool wear compensation data for TNo. 1 becomes:

(Wear compensation data) = (Programmed data) (Measured data)

= 30 30.24

= 0.24 (mm)

(2) Place the cursor on the data item in which you want to set data.

(3) Set the value that was calculated during step (1) above.

Note: Do not apply tool wear compensation to line-machining under the XC mode. Other-

wise the workpiece cannot be machined into a desired machining shape as pro-

grammed, since the wear compensation X is always conducted along the X-axis of the

3. Setting tool life management data

The life of the tools mounted on the turret can be managed using one of three methods:

- Tool life management according to the machining time

- Tool life management according to the number of machined workpieces

- Tool life management according to the amount of wear

Note: The life of a FLASH-tool can only be managed according to the machining time (or

application time).

A. Tool life management according to the machining time

(1) Place the cursor on the data item LIFEof the TIMEcolumn.

(2) Set the maximum available machining time for the tool.

- The NC unit cannot manage the life according to the machining time for a tool whose

setting under TIME LIFEremains 0.

- The application time is automatically counted up during actual cutting feed of the tool, and

displayed in the data item USEDof the TIMEcolumn in minutes (according to the internal

processing in seconds). When the application time reaches the LIFEsetting, OVER willappear under STS in the TOOL LIST area with the tools display items TNo. (with an

arrow symbol for the application direction) and TOOL being highlighted in magenta.

- The display items TNo. (with an arrow symbol) and TOOL in the TOOL LIST area will

be highlighted in yellow when the tools application time approaches the LIFEsetting.

The judgment of the approach to the life time is made according to the following

parameters:

F82 bit 2 (Method of judgment)

= 0: The rate of the application time to the life time has reached the value of F77.

= 1: The remaining serviceable time has descended to the value of F77.

F77(Reference value of judgment)

F82 bit 2 = 0: Critical rate of the application time to the life time (in %).

F82 bit 2 = 1: Critical remaining serviceable time (in minutes).

Note 1: The expiry of the serviceable life will not merely be indicated by the display of OVER

under STS, but also cause the alarm 177 TOOL LIFE EXCEED TIME. The function for

automatic replacement of the life tool with a spare one can now be applied to continue

machining by suppressing the interruption of automatic operation due to the alarm.

Note 2: The judgment of tools approaching the expiry of their life is not effectuated if parameter

F77remains set to 0.

Note 3: The current value of the item USEDcan be changed manually as required.

7-41

Note 4: The method of counting the total application time of the FLASH-tool differs according to

the type of tool data being used. Time data on all turning tools of the same tool number

and the same index angle, is counted, irrespective of whether the tools are for face-

machining or back-machining.

0: If there is an available tool, the turning tool is not changed for a spare. However,when multiple tips are to be used for a milling tool, the change for a spare tool is

conducted if even one of the tips to be used has already arrived at its life.

1: Among all tools having the same tool number, when even one tip of the FLASH-tool

exists whose total operation time is already in excess of a predetermined life, the

FLASH-tool is judged to have reached its life and is therefore changed for a spare.

B. Tool life management according to the number of machined workpieces

(1) Place the cursor on the data item LIFEof the NUMBERcolumn.

(2) Set the maximum available number of workpieces to be machined by the tool.

- The NC unit cannot manage the life according to the number of machined workpieces for atool whose setting under NUMBER LIFEremains 0.

Note 1: The expiry of the serviceable life will not merely be indicated by the display of OVER

under STS, but also cause the alarm 178 USED TOOL NUMBER EXCEED. The

function for automatic replacement of the life tool with a spare one can now be applied

to continue machining by suppressing the interruption of automatic operation due to the

alarm.

Note 2: The current value of the item USEDcan be changed manually as required.

C. Tool life management according to the amount of wear

(1) Place the cursor on the data item Xof MAX WEAR.

(2) Set the maximum permissible amount of tool wear in the X-axis direction.

- If 0 remains set, tool life management according to the amount of wear in the X-axis

direction will not occur.

(3) Set the maximum permissible amount of tool wear in the Z-axis direction.

- If 0 remains set, tool life management according to the amount of wear in the Z-axis

direction will not occur.

Note: If, during automatic workpiece measurement or automatic nose measurement, the

absolute value of the data setting in the data item WEAR COMP exceeds the data

setting in the data item MAX WEAR, then the data will change into a reverse display

status and an alarm message 179 X-MAX OR Z-MAX OFFSET OVER will be

displayed to indicate that the tool life has expired and the tool must therefore be

replaced with a new one.

4. Setting easy wear compensation and constant wear compensation data

(1) Move the cursor to the desired data item.

(2) Set the data using numeric data keys.

7-1-9 Setting tool group numbers

If a group number is set for the tools that are to be used during execution of the program, thenext spare tool to be used will be auto-selected from tools of the same group number.

1. Selection of spare tools

As listed below, two methods are available to select spare tools. Either is to be selected by

setting 0 or 1 in bit 2 of parameter F84.

- F84bit 2 = 0: Group number scheme

- F84bit 2 = 1: Tool name scheme

A. Group number scheme

Tools of the same group number are all regarded as spare ones, and tools that have neither yet

reached their lives nor become damaged are automatically selected in order with the smallesttool number first.

B. Tool name scheme

Tools of the same tool name, the same nominal diameter, and the same suffix are all regarded

as spare ones, and tools that have neither yet reached their lives nor become damaged are

automatically selected in order with the smallest tool number first.

Note 1: If all spare tools have reached their lives or become damaged, life-expired one having

the largest tool number will be selected first.


51/54


7-51

Note 2: Provided that they are the same in tool number, tool name, and nominal diameter,

FLASH tools will be regarded as spare tools, even if they differ in suffix.

2. Designation of tool numbers in the EIA/ISO program

As listed below, two methods are available to designate tool numbers in the EIA/ISO program.

Either is to be selected by setting 0 or 1 in bit 4 of parameter F94.

- F94bit 4 = 0: Group number designation scheme

- F94bit 4 = 1: Tool number designation scheme

A. Group number designation scheme

The T-command in the program is taken as the command for group number (GROUP No.). Tools

with the same GROUP No. as that of the commanded GROUP No. are selected as spare tools.

In this group number designation sheme, T01 in the program is taken as a command for group

No. 1. In case the group number 1 has been assigned for TNo. 2 and TNo. 3 on the TOOL

DATAdisplay, the tool of TNo. 3 is selected if the life of the tool of TNo. 2 has already expired.

B. Tool number designation scheme

The T-command in the program is taken as the command for tool number (TNo.). Tools with the

same GROUP No. as that of the commanded TNo. are selected as spare tools.

In this tool number designation sheme, T01 in the program is taken as a command for TNo. 1. In

case the group number 2 has been assigned for TNo. 1 and TNo. 4 on the TOOL DATAdisplay,

the tool of TNo. 4 is selected if the life of the tool of TNo. 1 has already expired.

Note: For both schemes, if there are multiple tools of the same group number, the

appropriate tool will be selected according to the particular method of selecting spare

tools.

7-1-10 Manual measurement of tool lengths (Setting tool length offset data using the

LENG-OFS TEACH menu function)

The [LENG-OFS TEACH]menu function can be used to set tool length data in the LENG CO.

B. during tool path check

C. during tool layout


53/54


7-53

A. Automatic operation

The machine action differs as follows between MAZATROL program automatic operation and

EIA/ISO program automatic operation:

1. MAZATROL program operation

Invalid tools are excluded from a list of usable tools. An alarm 626 NO TOOL IN MAGAZINE

will be displayed if an alternative, usable tool of the same type is not present.

2. EIA/ISO program operation

The MAZATROL tool data invalidation option is inoperative for automatic operation using

EIA/ISO programs, since the EIA/ISO program normally operates independently of

MAZATROL tool data. Only if MAZATROL tool length and diameter offset data is valid for

EIA/ISO program, however, does this option become operative. In this case, if the

MAZATROL tool data of the selected tool number is invalid, operation will stop with the

display of an alarm 653 ILLEGAL TOOL DESIGNATED after tool change has been done.

(a) If MAZATROL tool length and diameter offset data is valid (that is, if tool diameter

offset is made valid using bit 7 of user parameter F92 and tool length data is made

valid using bit 3 of user parameterF93):

Operation will stop with the display of an alarm 653 ILLEGAL TOOL DESIGNATED.

(b) If MAZATROL tool length and diameter offset data is invalid:

Normal operation continues.

Note: Operation will also stop with an alarm display, if a block that contains a com
