OF OPERATION OF
CNC MACHINE
TOOL
When machining the part using the CNC machine tool, first prepare the
program, then operate the CNC machine by using the program.
1) First, prepare the program from a part drawing to operate the CNC
machine tool.
How to prepare the program is described in the Chapter II.
PROGRAMMING.
2) The program is to be read into the CNC system. Then, mount the
workpieces and tools on the machine, and operate the tools according
to the programming. Finally, execute the machining actually.
How to operate the CNC system is described in the Chapter III.

NOTES ON READING THIS MANUAL
1) The function of an CNC machine tool system depends not only on the
CNC, but on the combination of the machine tool, its magnetic
cabinet, the servo system, the CNC, the operator’s panels, etc. It is too
difficult to describe the function, programming, and operation relating
to all combinations. This manual generally describes these from the
stand–point of the CNC. So, for details on a particular CNC machine
tool, refer to the manual issued by the machine tool builder, which
should take precedence over this manual.
2) Headings are placed in the left margin so that the reader can easily
access necessary information. When locating the necessary
information, the reader can save time by searching though these
headings.
Machining programs, parameters, variables, etc. are stored in the CNC unit
internal non–volatile memory . In general, these contents are not lost by the
switching ON/OFF of the power. However , it is possible that a state can occur
where precious data stored in the non–volatile memory has to be deleted,
because of deletions from a maloperation, or by a failure restoration. In order
to restore rapidly when this kind of mishap occurs, it is recommended that
you create a copy of the various kinds of data beforehand.
This manual describes as many reasonable variations in equipment usage
as possible. It cannot address every combination of features, options and
commands that should not be attempted.
If a particular combination of operations is not described, it should not be attempted.

Feedrates can be specified by using actual numerics. For example, to feed

The function of deciding the feed rate is called the feed function (See

Reference Position

Explanations
A CNC machine tool is provided with a fixed position. Normally, tool
change and programming of absolute zero point as described later are
performed at this position. This position is called the reference position.

Table
Fig. 1.3 (a) Reference position
The tool can be moved to the reference position in two ways:
(1)Manual reference position return (See III–3.1)
Reference position return is performed by manual button operation.
(2)Automatic reference position return (See II–6)
In general, manual reference position return is performed first after the
power is turned on. In order to move the tool to the reference position
for tool change thereafter, the function of automatic reference position
return is used.

Coordinate system
The following two coordinate systems are specified at different locations:
(See II–8)
(1)Coordinate system on part drawing
The coordinate system is written on the part drawing. As the program
data, the coordinate values on this coordinate system are used.
(2)Coordinate system specified by the CNC
The coordinate system is prepared on the actual machine tool table.
This can be achieved by programming the distance from the current
position of the tool to the zero point of the coordinate system to be set.

Methods of setting the
two coordinate systems
in the same position
The tool moves on the coordinate system specified by the CNC in
accordance with the command program generated with respect to the
coordinate system on the part drawing, and cuts a workpiece into a shape
on the drawing.
Therefore, in order to correctly cut the workpiece as specified on the
drawing, the two coordinate systems must be set at the same position.
To set the two coordinate systems at the same position, simple methods
shall be used according to workpiece shape, the number of machinings.
(1) Using a standard plane and point of the workpiece.

Command for moving the tool can be indicated by absolute command or
incremental command (See II–9.1).
The tool moves to a point at ”the distance from zero point of the

CUTTING SPEED –
SPINDLE SPEED
FUNCTION
Examples
The speed of the tool with respect to the workpiece when the workpiece
is cut is called the cutting speed.
As for the CNC, the cutting speed can be specified by the spindle speed
in rpm unit.

Spindle speed N
rpm
Workpiece
Tool diameter
φD mm
V: Cutting speed
m/min
<When a workpiece should be machined with a tool 100 mm in
diameter at a cutting speed of 80 m/min. >
The spindle speed is approximately 250 rpm, which is obtained from
N=1000v/πD. Hence the following command is required:
S250;
Commands related to the spindle speed are called the spindle speed
function ( See II–10) .

SELECTION OF TOOL
USED FOR VARIOUS
MACHINING – TOOL
FUNCTION
Examples
When drilling, tapping, boring, milling or the like, is performed, it is
necessary to select a suitable tool. When a number is assigned to each tool
and the number is specified in the program, the corresponding tool is
selected.
Tool number
01
02
A TC magazine
<When No.01 is assigned to a drilling tool>
When the tool is stored at location 01 in the ATC magazine, the tool
can be selected by specifying T01. This is called the tool function (See
II–11).
