From figure above one can see, a CNC system consists of basic function, optional functions and interfaces, etc., different machines will have different optional functions and interface designs. Please look up the manual from the machine builder.
(2) As mentioned above, KND 1000 CNC system is a universal system. This manual provides a general description about various functions of the CNC system. For a machine designer, in addition to read this manual, he shall also read the connection manual, only in this way can he understand in an all-sided way the functions of the system. And only based on above, can he give play to these functions optimally so that the machine tool can reach its optimal performance. In addition, this manual is only a description about functions, for a certain function, it is different on different machines, and it’s impossible to present all examples for concrete use, so please do refer to the manual from the machine builder.
(3)This manual is prepared based on system main board version 0012I-0000- W01Z-0108, and system software version K1000TA A01_060817.
(4)As for the differences of systems with other software versions, please refer to “Additional Description”.
(5)If program the PLC procedure by yourself, please read PLC USERS
MANUAL carefully.
Important:
K1000T system is of electronic disk function. After commissioning the machine, please save current data of the system into the electronic disk. In this way, it is possible to restore the system rapidly when current data of system is lost and becomes disorder hence can’t work. As for the operating way please refer to “Operation 12-2”.

1. GENERAL
1.1 TOOLMOVEMENT ALONG WORKPIECE PARTS FIGURE——INTERPOLATION
The tool moves along straight lines and arcs constituting the workpiece parts figure
(See II-4).
1.1.1 Tool movement along a straight line
Fig. 1.1.1 Tool movement along the straight line which is parallel to Z–axis
1.1.2 Tool movement along an arc
Fig. 1.1.2 Tool movement along an arc
1.1.3 Thread cutting
Threads can be cut by moving the tool in synchronization with spindle rotation.1 Straight thread cutting
PROGRAMMING 1 GENERAL 1 2
2 Taper thread cutting
The term interpolation refers to an operation in which the tool moves along a straight line or arc in the way described above.
Symbols of the programmed commands G01, G02, ... are called the preparatory function and specify the type of interpolation conducted in the control unit.
PROGRAMMING 1 GENERAL 1 3
1.2 FEED–FEED FUNCTION
Movement of the tool at a specified speed for cutting a workpiece is called the feed.
Feedrates can be specified by using actual numerics. For example, the following command can be used to feed the tool 150 mm/s——F150.
The function of deciding the feed rate is called the feed function(SeeII–6).
1.3 PART DRAWING AND TOOL MOVEMENT
1.3.1 Reference position (Machine–Specific Position)
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.
The tool can be moved to the reference position in two ways:Manual reference position return
Automatic reference position return
1.3.2 Coordinate system on part drawing and coordinate system specified by CNC coordinate system
PROGRAMMING 1 GENERAL 1 4
The following two coordinate systems are specified at different locations: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.
Coordinate system specified by the CNC
The coordinate system is prepared on the actual machine tool. 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.
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.
PROGRAMMING 1 GENERAL 1 5
Methods of setting the two coordinate systems in the same position
The following method is usually used to define two coordinate systems at the same
location.
1. When coordinate zero point is set at chuck face
Fig. Coordinates and dimensions on part drawing
Fig. Coordinate system on lathe as specified by CNC (made to coincide with the coordinate system on part drawing)
2. When coordinate zero point is set at work end face.

(made to coincide with the coordinate system on part drawing)
1.3.3How to indicate command dimensions for moving the tool absolute, incremental commands
Coordinate values of command for moving the tool can be indicated by absolute or
incremental designation (See II–9).Absolute commands
The tool moves to a point at ”the distance from zero point of the coordinate system” that is to the position of the coordinate values.
( ) Incremental comands
Specify the distance from the previous tool position to the next tool position.
PROGRAMMING 1 GENERAL 1 7
1.3.4 Diameter programming /radius programming
Dimensions of the X axis can be set in diameter or in radius. Diameter
programming or radius programming is employed independently in each machine. 1. Diameter programming
In diameter programming, specify the diameter value indicated on the drawing as the value of the X axis.
2. Radius programming
In radius programming, specify the distance from the center of the workpiece, i.e. the radius value as the value of the X axis.
PROGRAMMING 1 GENERAL 1 8
1.4 CUTTING SPEED –SPINDLE SPEED FUNCTION
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. EXAMPLE:
<When a workpiece 100 mm in diameter should be machined at a cutting speed of 80 mm/min. >
The spindle speed is approximately 250 rpm, which is obtained from N=1000v/_D. Hence the following command is required:S250
Commands related to the spindle speed are called the spindle speed function (See II–10)
The cutting speed v (m/min) can also be specified directly by the speed value. Even when the workpiece diameter is changed, the CNC changes the spindle speed so that the cutting speed remains constant.
This function is called the constant surface speed control function.
PROGRAMMING 1 GENERAL 1 9
1.5SELECTION OF TOOL USED FOR VARIOUS MACHINING – TOOL
FUNCTION
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. EXAMPLE:
<When No.01 is assigned to a roughing tool>
When the tool is stored at location 01 of the tool post, the tool can be selected by specifying T0101.
This is called the tool function.
1.6 COMMAND FOR MACHINE OPERATIONS MISCELLANEOUS FUNCTION
When machining is actually started, it is necessary to rotate the spindle, and feed coolant. For this purpose, on–off operations of spindle motor and coolant valve should be controlled.
The function of specifying the on–off operations of the components of the machine is called the miscellaneous function. In general, the function is specified by an M code. (See II–11)
For example, when M03 is specified, the spindle is rotated clockwise at the specified spindle speed.

A group of commands given to the CNC for operating the machine is called the program. By specifying the commands, the tool is moved along a straight line or an arc, or the spindle motor is turned on and off. In the program, specify the commands in the sequence of actual tool movements.
A group of commands at each step of the sequence is called the block.
The program consists of a group of blocks for a series of machining. The number for discriminating each block is called the sequence number, and the number for
discriminating each program is called the program number (See II–13.)
1.7.1Block
The block and the program have the following configurations.
Each block starts with a sequence number which identifies the block, and ends
with an end–of–block code which indicates the end of the block. This manual indicates the end–of–block code by ;
PROGRAMMING 1 GENERAL 1 11
1.7.2 Program
Normally, a program number is specified after the end–of–block (;) code at the beginning of the program, and a program end code M30 is specified at the end of the program.
1.7.3 Main program and subprogram
When machining of the same pattern appears at many portions of a program, a program for the pattern is created. This is called the subprogram. On the other hand, the original program is called the main program. When a subprogram execution command appears during execution of the main program, commands of the subprogram are executed. When execution of the subprogram is finished, the sequence returns to the main program.

1.8 TOOL COMPENSATION FUNCTION
1.8.1 Tool offset
Usually, several tools are used for machining one workpiece. The tools have different tool length. It is very troublesome to change the program in accordance with the tools.
Therefore, the length of each tool used should be measured in advance.
By setting the difference between the length of the standard tool and the length of each tool in the CNC (data display and setting : see III–15), machining can be performed without altering the program even when the tool is changed. This function is called tool length compensation.
1.9 TOOL MOVEMENT RANGE—— STROKE
Limit switches are installed at the ends of each axis on the machine to prevent tools from moving beyond the ends. The range in which tools can move is called the stroke.

3.PREPARATORY FUNCTION G FUNCTION
A number following address G determines the meaning of the command for the concerned block. G codes are divided into the following two types.
Type
One-shot G code
Modal G code
Meaning
The G code is effective only in the block in which it is specified.
The G code is effective until another G code of the same group is specified.
Example:
G01 and G00 are modal G codes in group 01.
G01X _;
Z _; G01 is effective in this range.
X _;
G00 Z_;
NOTE
1. Modal G codes have the following initial conditions when the power is turned on or the system is reset to the clear state.
1)Those G codes marked* in Table 3 are specified automatically.
2)G20 and G21 retain their original conditions.
3) G00 or G01 is automatically selected according to parameter setting.
2.The G codes of group 00 are one-shot G codes.
3.If a G code that does not appear in the G code list is specified, or a G code whose options are not supported is specified, alarm No. 010 is displayed.
4.Multiple G codes of different groups can be specified in a single block. When multiple G codes of one group are specified in a block, the G code specified last is effective.
5.G code can set the max speed of spindle in constant surface speed control.
6.A G code is displayed from each group.
