1-1 Items requiring attention when reading this manual.
∑10L/16T/18T/21L program part” and for
∑10/16/18/21 maintenance part”
(1) In this manual and the reference manual “program part”, explanations are made on all the
functions that are applicable to these NC machines, including optional functions. The option
function selected for adoption are different for each machine. Please confirm the
specification of the machine beforehand, as there may be some functions referred to in the
manual are not usable depending on the machine.
(2) In this manual, those functions not specifically remarked “able” should be understood as
“unable”.
(3) The contents of this manual may be changed without notice to meet a future machine
improvement.
Note) Programs, parameters, macro variables and tool compensation amounts, etc. are stored in
the memory of NC unit. Generally, these dat a are not lost by switching the power ON/
OFF.
Nevertheless, data could be lost inadvertently or by erroneous operation. Also a case
may occur when you are compelled to have valuable date in the memory cleared for
restoring the system from a trouble.
To cope with such an unexpected situation, we suggest that you take note of the important
data and keep them separately . It facilit ates quick restoration of working condition of the
machine by re-entering the data.
Note) When processing a work, do not start the operation suddenly . Make a trial warm-up run
first for fully confirming that the machine acts correctly , then proceed with subsequent
operating procedures.

2. INTERPOLATING FUNCTIONS
2-1 Positioning (G00)
Each axis can be fed at a rapid traverse rate independently by specifying G00.
2-2 Linear Interpolation (G01)
Linear interpolation is performed at the feed rate specified by an F-code in a G01 command.
2-3 ANGLE DESIGNATION LINEAR INTERPORATION (G01)
With G01, an angle from Z axis is specified where linear interpolation is commanded.
2-4 Circular Interpolation (G02, G03)
Circular interpolation can be performed arbitrarily at 0 to 360° at the feed rate specified by an Fcode in a G02 or G03 command.
2-5 Radius Designation on Arc (G02, G03)
R can be directly specified as a circular arc radius value, assuming, I, J, and K to be a vector
amount from a start point to the center in circular interpolation.
2-6 Sine Curvilinear Interpolation <Virtual Axis Interpolation> (G07)
Not available with
By performing interpolation without moving one axis within a circular arc plane (hypothetical
axis) in a helical cutting command, sine curvilinear interpolation is performed between the
remaining two axes.
2-7 Helical Cutting......Not available with
Another axis is linearly interpolated synchronously with circular interpolation.

2-8 Polar Coordinate Interpolation
A command programmed in the orthogonal coordinate system is converted into a linear axis
move (tool) and rotary axis move (work rotation) to control a profile.
2-9 Cylindrical Interpolation
If a linear axis stroke and rotary axis angle are specified by a program command, the rotary axis
stroke internally specified in terms of angle is converted into a distance on the circumference.
As the distance on the circumference can be regarded a linear axis stroke on the
circumference, linear interpolation and circular interpolation can be performed in combination
with other linear axis.

3. THREADING
3-1 THREADING (G32)
With F or E code, a thread lead is directly commanded. With E code, you can assign the
number of thread ridges per inch can be assigned by a parameter .
3-2 MULTIPLE THREADIGN (G32)
Use this to perform multiple thread cutting which has two or more thread ridges in a lead. With
Address Q, command a threading start shift angle. be performed.
3-3 VARIABLE LEAD THREADING
By commanding the increase or decrease amount in lead per one screw thread turning, you can
perform variable lead threading. With Address K, command a lead changing amount.
4. FEED FUNCTION
4-1 RAPID TRAVERSE RATE AND RAPID OVERRIDE
The maximum speed available in the axial direction is 240,000mm/min (IS-B). Further, override
can be applied to rapid traverse by rapid override.
4-2 CUTTING FEED RATE AND FEED OVERRIDE
The maximum feed rate range available for setting is 6~240,000mm/min (IS-B).
Override can be applied, by feed rate override, within a range of 0~200% by every 10%.

4-3 Override Cancel
A cutting feed override rate can be fixed at 100 % by a signal from the machine.
4-4 Automatic Acceleration/Deceleration
Linear acceleration/deceleration is performed in case of rapid traverse, and exponential function
type acceleration/deceleration is performed in case of cutting feed or jog feed.
4-5 Dwell (G04)
Migration to operation in the next program block can be delayed by a specified time by a G04
command. Use P, X, or U for an address.
4-6 Exact Stop Check (G09)
In the block where G09 is specified, an imposition check is made at the end of block execution.
4-7 Exact Stop Check Mode (G61)/Cutting Mode (G64)
Normally, the G64 mode is effected and the program proceeds to the next block immediately
after interpolation is completed. If G61 is specified, the program will proceed to the next block
after entering imposition at the end point of each block, in the subsequent move command. The

2 - 10
13. TOOL OFFSET FUNCTIONS
13-1 Automatic Tip R Compensation and Cutter Compensation
(1) Automatic Nose R Compensation (G143)
It is normally held at G143 (Automatic Nose R Compensation Valid Mode). Therefore,
without G code not being commanded, tip R compensation is automatically executed.
Nose R is set to tool compensation R and virtual nose points (1~8) to T.
(2) Cutter Compensation (G145 : G40~G42)
With G145 command, Cutter Compensation mode is created.
With G40~G42 commands while in this mode, cutter compensation can be carried out.
A tool diameter is set to tool compensation R and a virtual nose point (9) to T.
13-2 Groove Width Compensation (G150 to G152)
When a grooving tool is used, one virtual tool nose (for example, 3) is used to run the program
to apply compensation. It is also necessary to compensate the other virtual tool nose (for
example, 4) side. When this is done, this function compensates the groove width by specifying
a G-code.
13-3 Addition of T ool Offset s
The number of tool offset pairs can be expanded up to 200.
Expansion of tool offset pairs: 64/99/200 (Up to 99 pairs for the
Note) The number of tool offset pairs, 200, is only allowed when the ATC is attached.

G31, the next block will be executed, canceling the rest of this command. A skip signal input
position can be read with a system macro variable.
15-2 Q SETTER
Through simple manual operation with the touch sensor, tool offset volume is automatically
written.
15-3 Q-setter Repeat Function
By measuring the tool with the Q-setter once, automatic measurement with the Q-setter is
activated by simple operation when changing tips.
16. CUSTOM MACRO
16-1 Custom Macro
A function peculiar to the user can be created. There are 100 common variables, but their
number can be optionally extended up to 600.
17. AXIS CONTROL
17-1 Follow-up Function
In case of emergency stop or servo alarm, a machine travel amount is reflected on an NC unit
internal position. For this reason, automatic operation is enabled after resetting the emergency
stop or servo alarm, even if you do not have to perform zero point return.
In case of speed feedback or position feedback alarm, however, an actual machine position and
the NC unit internal position do not match, because the follow-up function does not work
properly .
17-2 Mirror Image
This function can reverse the sign of the travel direction specified by a program command or
MDI command for the X-, Y-, Z-axis, or an additional axis. Make this setting in the Setting
screen.
2 - 12
18. MANUAL OPERATION
18-1 Manual Continuous Feed

Feed rates are as follows:
1 Jog feed
Jog feed rate can be changed over into 24 stages through use of the switch. Speed in 24
stages is set with parameters.
2 Manual rapid
When jog feed is executed as the rapid traverse button being pushed, manual rapid traverse
is available.
18-2 Manual Pulse Generator
The machine is capable of fine feed by means of the pulse generator on the machine operation
panel. One rotation of the pulse generator generates 100 pulses. You can select a scale factor
of x 1, x 10, or x M (M=1 to 100 set in a parameter) by a signal from the machine.
19. AUTOMATIC OPERATION
19-1 DNC Operation
With the optional board being added, DNC operation from the host CPU is made available.
19-2 Program Number Search

screen.
19-3 Sequence Number Search
A sequence number can e searched for in the program currently selected from the data in the
Program screen.
19-4 Restart of Program
To restart a program, there are three ways; program restart, block restart, and machining break
point return.
1 Program restart is a function to restart from the block of a specified sequence number.
2 Machining break point return is a function to position a tool to a break point by jog feed.
19-5 Sequence Number Comparison and Stop
If you encounter the block of a preset sequence number during program execution, the machine
stops after executing that block.
19-6 Preread Buffer
In order to avoid discontinuation of the program blocks at the time of cutting due to the
processing time of the NC unit, the preread buffer generally prereads one program block in case
of automatic operation.
2 - 13
(1) The preread buffer prereads the different number of program blocks, depending on the
function.
Function No. of pre-reading blocks
Automatic tip R compensation 4 blocks
Multi buffer 12 blocks
Tool diameter compensation 2 to 4 blocks
Others 0 or 1 block
Note 1) In the tool diameter compensation mode, the preread buffer prereads up to 4 blocks if
they contain the blocks free from an axis move command.
Note 2) The following commands suppress the preread buffer.
Example: G28, G30, G31, G53,
G10, G20, G21,
M00, M01, M02, M30
T Command
Note 3) As the automatic tip R compensation is normally held valid (G143 mode), pre-reading of
4 blocks is carried out.
(2) When the SINGLE BLOCK switch is turned on
(State in which automatic tip R compensation is held invalid : G140, G145 mode)
When the SINGLE BLOCK switch is turned on and the program blocks are executed
sequentially by pressing the CYCLE START switch, the preread buffer does not exist.
Because, when the CYCLE START switch is pressed, one program block is taken into the
preread buffer and executed immediately. Therefore, the preread buffer does not exist
during and after execution.
Note 1) Pre-reading is performed when any of the following applies:
(a) In Multi Buffer mode (G251)
(b) Tool radius compensation mode (G41, G42)
(c) When optional angle chamfering corner R is specified (, C/, R)
(d) Thread cutting (G32)
(e) T apping mode (G63)
Note 2) When the SINGLE BLOCK switch is turned from OFF to ON during automatic operation
to stop it, the preread buffer exists.
19-7 Feedhold
All axes can be stopped temporarily. Pressing the CYCLE START button restarts feeding the
axes. Prior to restarting axis feed, you can allow intervention by manual operation in the manual
mode.
2 - 14
19-8 External Reset and Reset Signal
The NC unit can be reset from the outside. A reset cancels all the commands and decelerates
the machine to a stop. A reset signal is output to the machine while the RESET button of the
