GENERAL SAFETY INSTRUCTIONS 0-1
0 GENERAL SAFETY INSTRUCTIONS
The hazards involved in operating the machine are identified by the following means:
- In this manual, warning notices serve to indicate aspects which are relevant to safety.
- On the machine, warning signs point out aspects which are relevant to safety.
0.1 Indicator words and their meaning
The indicator words use for warning notices are divided into the categories listed below, according to the
accepted degree of risk involved.
Consciously ignoring these warning notices can result in accidents, serious injuries or death.
Furthermore, serious damage may be caused to the machine and its auxiliary units. The warning notices
below must there be followed without fail!
DANGER!
Indicator word used to denote an immediately hazardous situation which, if not avoided,
will result in serious injury or death.
WARNING!
Indicator word used to denote a potentially hazardous situation which, if not avoided,
could result in serious injury or death.
CAUTION!
Indicator word used to denote a potentially hazardous situation which, if not avoided,
could result in slight to moderate injuries.
NOTICE! Indicator word used to denote a potentially hazardous situation which, if not avoided,
could result in damage to property.
REMARK Indicator word used to point out important or useful information.

REMARK 1. Read this manual carefully before operating the machine.
2. Store this manual in a clearly marked location for easy reference.

In “Tool data” screen of Professional 6, there is column of the length of the tool “H (Geometry)”, and actual
length of the tool of each tool is registered there. The operator registers this data with the MDI key on the
tool data screen usually.
Usually machining is performed according to this tool length.
When a machining is performed with this tool length that is extremely different from the tool length intended by an NC programmer (a person managing the tools), there is a possibility of damaging the spindle by an empty operation, an overlord operation, an interference of the tool to a work, etc.
To prevent this, “Nominal Length” column was introduced into “Tool data” screen of Professional 6. The
programmer registers the length of a standard tool and it is possible to stop the machining program by
comparing the length of the tool by the NC program with the length of a standard tool.
REMARK This is restricted to only when the Tool Offset Data Transfer Command (M56) is being
used.

2.1 Display of the Standard Tool Length at the “Tool Data” Screen
The standard tool length is displayed at the “Tool Data” screen of the Professional 6 as shown below:
This is where an NC programmer (a person managing the tools) registers the data. In addition to a registration by the tool data screen, the registration is also possible by NC programs. (Refer to “3.2 Entering the
Standard Tool Lengths from an NC Program”.)
Fig. 2-1:
REMARK If the standard tool length “Nominal Length” is not currently displayed at the “Tool Data”
screen, it can be brought up by the standard procedure:
1. Display the context menu on the Tool Data screen, and select the “Screen Setting”.
2. Check the item described as “Nominal Length” on the “Tool Data List” tab.
3. Press the [OK] button.
For more information, refer to the section “3.9 Setting Screen” of the tool data screen of
the screen part in the Professional 6 operation manual.
2.2 Using the Standard Tool Length
Comparison between a tool length and a nominal tool length is performed when a specific M code
(M1423) is commanded.
The comparison is not performed when registering or changing data.
Here, the tool length denotes the sum of an offset length (H (geometry)) and an offset length (H (wear)).
When the M1423 is executed, the tool length and the nominal tool length of a tool mounted to the spindle is calculated by the following formula.
The machine alarm goes off in the following cases.

[1] Standard tool length => Nomi-
nal length: Nominal

“Nominal Length: Tolerance (−)”
[3] Plus side allowable value
“Nominal Length: Tolerance (+)”
[4] Tool length (geometry + wear)
Within the range: this is OK.

STANDARD TOOL LENGTH DATA 3-1
3 STANDARD TOOL LENGTH DATA
Like other tool data, the standard tool length data can also be outputted to the macro variables, registered
from NC programs, and outputted to the tool data file.
3.1 Copying the Standard Tool Lengths into Macro Variable
Similarly with the other tool data items, the standard tool length data can be copied into the macro variable with M483 code. #102=502.0 must be specified to refer to the standard tool length (see the following
examples):
Program example 1
The standard tool length data of the tool, currently fixed in the spindle, is copied into the macro
variable #110
#100=1.0; (Tool Data)
#101=0.0; (Spindle Pot)
#102=502.0; (Standard tool length)
M483;
Program example 2
The standard tool length of the pot No. 7, which is currently in the tool magazine, is copied into
macro variable #110
#100=1.0; (Tool Data)
#101=7.0; (Composite tool pot No.7 in the magazine)
#102=502.0; (Standard tool length)
M483;
3.2 Entering the Standard Tool Lengths from an NC Program
Similarly with the other tool data items, the standard tool length data can be entered from an NC program
with M448 and M449 codes. S502 must be specified to refer to the standard tool length (see the following
examples).
Program example 1
The standard tool length data are input for a series of tools by M448.
M448 S502; (Input “Nominal Length: Nominal”)
S1 T1000000; (100.0 mm to pot 1)
S2 T2000000; (200.0 mm to pot 2)
S3 T3000000; (300.0 mm to pot 3)
M448;
Program example 2
T number, FTN and Nominal Length: Nominal are input to the tool of 1st pot by M449.
M449 S1; (Input data to the 1st pot tool)
S004 T1; (“T number” is 1)
S005 T1; (“FTN” is 1)
S502 T1000000; (“Nominal Length: Nominal” is 100.0[mm])
M449;
