1.2 CNC System of Machine Tools and CNC Machine Tools
CNC machine tool is an electro-mechanical integrated product, composed of Numerical Control
Systems of Machine Tools, machines, electric control components, hydraulic components, pneumatic
components, lubricant, cooling and other subsystems (components), and CNC systems of machine
tools are control cores of CNC machine tools. CNC systems of machine tools are made up of
computerized numerical control(CNC), servo (stepper) motor drive devices, servo (or stepper) motor
etc.
Operational principles of CNC machine tools: according to requirements of machining
technology, edit user programs and input them to CNC, then CNC outputs motion control commands
to the servo (stepper) motor drive devices, and last the servo (or stepper) motor completes the cutting
feed of machine tool by mechanical driving device; logic control commands in user programs to
control spindle start/stop, tool selections, cooling ON/OFF, lubricant ON/OFF are output to electric
control systems of machine tools from CNC, and then the electric control systems control output
components including buttons, switches, indicators, relays, contactors and so on. Presently, the
electric control systems are employed with Programmable Logic Controller (PLC) with characteristics
of compact, convenience and high reliance. Thereof, the motion control systems and logic control
systems are the main of CNC machine tools.
GSK980TDc Turning Machine CNC system has simultaneously motion control and logic control
function to control two axes of CNC machine tool to move, and has nested PLC function. Edit PLC
programs (ladder diagram) according to requirements of input and output control of machine tool and
then download them to GSK980TDc Turning Machine CNC system, which realizes the required
electric control requirements of machine tool, is convenient to electric design of machine tool and
reduces cost of CNC machine tool.
Software used to control GSK980TDc Turning Machine CNC system is divided into system
software (NC for short) and PLC software (PLC for short). NC system is used to control the display,
communication, edit, decoding, interpolation and acceleration/deceleration, and PLC system for
controlling explanations, executions, inputs and outputs of ladder diagrams.
Standard PLC programs are loaded (except for the special order) when GSK980TDc Turning
Machine CNC System is delivered, concerned PLC control functions in following functions and
operations are described according to control logics of standard PLC programs, marking with
“Standard PLC functions” in GSK980TDc Turning CNC System User Manual. Refer to Operation
Manual of machine manufacturer about functions and operations of PLC control because the
machine manufacturer may modify or edit PLC programs again.

1.3 Programming Fundamentals
1.3.1 Coordinates definition
Sketch map of CNC turning machine is as follows:
Fig. 1-3
GSK980TDc uses a rectangular coordinate system composed of X, Z axis. X axis is
perpendicular with axes of spindle and Z axis is parallel with axes of spindle; negative directions of
them approach to the workpiece and positive ones are away from it.
There is a front tool post and a rear tool post of NC turning machine according to their relative
position between the tool post and the spindle, Fig. 1-4 is a coordinate system of the front tool post
and Fig. 1-5 is a rear tool post one. It shows exactly the opposite of X axes, but the same of Z axes
from figures. In the manual, it will introduce programming application with the front tool post
coordinate system in the following figures and examples.

1.3.2 Machine coordinate system, Machine Zero and machine reference point
Machine tool coordinate system is a benchmark one used for CNC counting coordinates and a
fixed one on the machine tool. Machine tool zero is a fixed point which position is specified by zero
switch or zero return switch on the machine tool. Usually, the zero return switch is installed on max.
stroke in X, Z positive direction. Machine reference point is located at the position at which the
machine zero value adding the data parameter No.114/No.115 value. When No.114/No.115 value is 0,
the machine reference point coincides with the machine zero. The coordinates of machine reference

point is the No.120/No.121 value. Machine zero return/G28 zero return is to execute the machine
reference point return. After the machine zero return/machine reference point return is completed,
GSK980TDc machine coordinate system which takes No.120 value as the reference point, which is
referred to I Programming, Section 3.13.
Note: Do not execute the machine reference point return without the reference point switch installed on the
machine tool, otherwise, the motion exceeds the travel limit and the machine to be damaged.
Ⅰ Programming
1.3.3 Workpiece coordinate system and Program Zero
The workpiece coordinate system is a rectangular coordinate system based on the part drawing,
also called floating coordinate system. After the workpiece is installed on the machine, the absolute
coordinates of tool’s current position is set by G50 according to the workpiece’s measure, and so the
workpiece coordinate system is established in CNC. Generally, Z axis of the workpiece coordinate
system coincides with the spindle axis. The established workpiece is valid till it is replaced by a new
one. The system can set 6 workpiece coordinate systems G54~G59 in advance. Refer to I
Programming, Section 3.18 about the details of workpiece coordinate system.
A sub workpiece coordinate system is created in a workpiece coordinate system, which is called
as a local coordinate system. Refer to I Programming, Section 3.17 about the details of the local
coordinate system.
The current position of workpiece coordinate system set by G50 is the program zero.
Note: Do not execute the machine reference point return without using G50 to set the workpiece coordinate
system after power on, otherwise, the alarm occurs.

1.3.4 Interpolation function
Interpolation is defined as a planar or three dimensional contour formed by path of 2 or multiple
axes moving at the same time, also called Contour control. The controlled moving axis is called link
axis when the interpolation is executed. The moving distance, direction and speed of it are controlled
synchronously in the course of running to form the required Composite motion path. Positioning
control is defined that motion end point of one axis or multiple axes instead of the motion path in the
course of running is controlled.
GSK980TDc X and Z axis are link axes and 2 axes link CNC system. The system possesses
linear, circular and thread interpolation function.
Linear interpolation: Composite motion path of X, Z axis is a straight line from starting point to
end point.
Circular interpolation: Composite motion path of X, Z axis is arc radius defined by R or the circle
center (I, K) from starting point to end point.
Thread interpolation: Moving distance of X or Z axis or X and Z axis is defined by rotation angle
of spindle to form spiral cutting path on the workpiece surface to realize the
thread cutting. For thread interpolation, the feed axis rotates along with the
spindle, the long axis moves one pitch when the spindle rotates one rev,
and the short axis and the long axis directly interpolate.

incremental programming and compound programming.
Programming with X/Z axis absolute coordinate value to program (present with X, Z) is defined to
be the absolute programming;
Programming with X/Z axis incremental movement (present with U, W) is defined to be the
incremental programming;
In the system, X, Z axis separately uses the absolute programming and incremental program,
which is called the compound programming.
Example: A→B linear interpolation
Fig.1-8
Absolute programming: G01 X200 Z50;
Incremental programming: G01 U100 W-50;
Compound programming: G01 X200 W-50; or G01 U100 Z50
Note: When there are command address X/ U or Z/ W at the same time, X/Z command value is valid.
Example: G50 X10 Z20;
G01 X20 W30 U20 Z30; 【End point of the block (X20, Z30)】
1.3.6 Diameter programming and radius programming
Programming methods of X coordinate values are divided into: diameter programming and
radius programming.
Diameter programming: when NO.001 Bit2 is 0, X input command value is in diameter and X
coordinate is in diameter at the moment;
Radius programming: when NO.001 Bit2 is 1, X input command value is in radius and X
coordinate is in radius at the moment.

Except for addresses and data in Table 1-1, others (arc radius, taper in G90) are unrelated to
diameter or radius programming, and their input values in X direction are defined by the radius.
Note: The diameter programming is used except for the special description in the following explanation.

1.4 Structure of an NC Program
User needs to compile part programs (called program) according to command formats of CNC
system. CNC system executes programs to control the machine tool movement, the spindle
starting/stopping, the cooling and the lubricant ON/OFF to complete the machine of workpiece.
Program example:
Ⅰ Programming
Fig. 1-9
The tool leaves the path of A→B→C→D→A after the above-mentioned programs are executed.
1.4.1 General structure of a program
A program consists of blocks. A block begins with a block number (it can be omitted) and several
words ending with “;”. General structure of a program is shown in Fig.1-10:

Program name
There are most 384 programs stored in GSK980TDc. To identify it, each program has only one
program name (there is no the same program name) beginning with command address O and the
following 4 digits.
○ □□□□

composed of an English letter (called command address) and the following number (operation
command with/without sign). The command address describes the meaning of its following operation
command and there may be different meaning in the same command address when the different
words are combined together. All words of GSK980TDc are in Table 1-2.
A word is the basic command unit to command CNC system to complete the control function,
