II. Programming

2.1 General

2.1.1 Axes Definition

In this CNC system, the main two axis of motion of the lathe machine is referred to as X and Z axis in a right hand coordinate system. Since the spindle of the lathe is horizontal, the Z axis is horizontal as well, the cross axis is denoted by X.A positive motion in both X and Z direction moves the tool away from the workpiece. The figure below shows the coordinate system of front toolpost lathe system and rear toolpost lathe system. In the front toolpost system, a positive command moves the Z axis from left to right and the X axis from back to front. In this CNC system we use front toolpost system for introducing the programming. Front toolpost system Rear toolpost system

2.1.2 Reference Point (Machine Zero Point)

Reference point is a fixed position on a machine tool which the tool can easily be moved. Usually, the reference point is set at the max. travel position of each axis at positive direction. Don’t use the reference point return function (such as G28).if the reference point is not available on the corresponding machine tool.

2.1.3 Coordinate value and direction and dimension

In this system, there are two ways to command the travels of the tool, the absolute command and incremental command, the using of the absolute command and the incremental command depending

GUANGZHOU CNC EQUIPMENT CO., LTD.

GSK980T CNC SYSTEM USER MANUAL

on the address used. Absolute and incremental commands can be used together in one block. The format of the address is as follows:

X axis X U Z axis Z W

Address Absolute command Incremental command

2.1.4 Unit and Range of coordinate

The least input of this system is 0.001mm and the maximum input is ±9999.99.

Axis Least input unit Least motion increment

0.001mm(Diameter program) 0.0005mm X axis

0.001mm(Radius program) 0.001mm

Z axis 0.001mm 0.001mm

2.1.5 Initial and Modal Status of the Command

Initial status is the status of the control before it is programmed. Modal status means after the command is specified; it is effective until another command in the same group is specified .

2.1.6 The Start of a Program

At the beginning of program executing, the tool tips of the first programmed tool(standard tool)should be the start point of the programmed workpiece coordinate system. Usually, the first programmed tool is used as a standard tool which its offset compensation value is (0,0).

2.1.7 The End of a Program

Command code M30 is specified in the last block of a program to end the executing of a program. Before ending the executing of grogram by M30, the tool must be programmed to return to the start point of the workpiece coordinate system, and the corresponding tool offset compensation must be cancelled.

2.1.8 Program Configuration

The definition of the work coordinate system is depending on the start point of the tool in the corresponding work program by specifying a value after G50 is a floating coordinate, if G50 is not commanded the current absolute coordinate value is treated as the start point of the program. After a workpiece coordinate system is set, a point on the tool, such as the tool tip, is at specified coordinate.

2.1.9 Program Configuration

When machining of the same pattern appears at many sections of a workpiece program, a program for this pattern is created first, this is called the subprogram, on the other hand, the original program is called the main program. When a subprogram execution command is executed during the executing of the main program, commands of the subprogram are executed. When the executing of the subprogram is finished, the sequence returns to the main program.

In general, the thread cutting need to repeat along the same path in rough cutting through finish cuts for a thread. Since the thread cutting starts when a I-revolution signal is output from the spindle position encoder, thread cutting is started at a fixed point and the tool path on the workpiece is unchanged for repeated threading cutting. The spindle speed must remain constant from rough cutting through finish cutting. if not, thread lead error will occur.

2.3.7 Work Coordinate System Setting(G0)

A work coordinate system can be set using the following the blow command:

G50 X(x) Z(z); Use this command to set a coordinate system ,this coordinate system is referred as a workpiece coordinate system, so a point on the tool, such as the tool tip ,is specified as coordinate value(x, z). Once a workpiece coordinate system has been set, the absolute position of following blocks is specified according to this coordinate system When diameter programming, X address is specified by diameter value. When radius programming, X address is specified by radius value.

As illustrated in above figure, the reference point on the turret is superposition with the start point, and the coordinate system is set by G50 at the start of the program. Thus, when an absolute command is carried out, The start point will move to the position commanded. In order to move the tool tip to the position commanded, the difference between the reference and the tool tip is compensated by the too offset.

Note: If the coordinate system setting is carried out by G50, a coordinate system in which the position prior to the effecting of the offset becomes the designated position, is set.

2.3.8 Feed per Minute (G98)

G98 specify the feed per minute, a number follows F specify the amount of feed of the cutting tool per minute. G98 is a modal code. Once a G98 is specified, it is available until a G99 (feed per revolution )is specified.

2.3.10 Constant Surface Speed Control(G96, G97)

When the surface speed is set by a value after address S, and the spindle speed is calculated according to the relative position between the tool and the workpiece to keep the surface speed always the specified value, so-called constant surface speed control. Voltage is fed to the spindle control section so that the spindle rotates to produce the correct surface speed. The units of the surface speed is as follows:

Input unit Surface speed unit Metric system m/min

The units of the surface speed depend on the setting of the machine tool builder. The Constant surface speed control is specified by the follow command:

G96 S__; The surface speed is set after address S. The constant speed control can be canceled by the following command:

G97 S__; The spindle speed is set after address S. It is necessary to apply the constant speed control on Z axis.

The CNC use the programmed coordinate value on the X axis to calculate the surface speed. When offset compensation is valid, this is not the value calculated according to the X axis coordinate after offset. At the end point N15 in example above is not the turret center, but the tool nose, that is to say at 600dia, the surface speed is 200m/min. If X axis coordinate value is negative, the CNC uses the absolute value.

2.7 Program Configuration

2.7.1 Program

A program consists of group of blocks, which contains addresses information necessary for machining. One block is separated from another with and End of block code (For ISO code is LF, for EIA code is CR).

(1) Main Program and Subprogram (a) Subprogram

Program can be divided into two types, main program and subprogram. Normally, the CNC operates according to the main program. When a calling subprogram command is encountered in the executing of the main program, control is passed to the subprogram. When a return to main program command is encountered in the subprogram, control is returned to the main program.

Main Program Subprogram

Command 1

Command 2

... ... ...

Subprogram Calling command

Command n

... ... ...

Comman

... ... ...

Return to the main program

The Memory of CNC can store up to 63 main program and subprograms(standard specification). A main program can be selected to operate the CNC machine.

(b) Subprogram

If a fixed sequence appears repeatedly in a program, this sequence can be stored as a subprogram in the memory to simplify the program. The main program can call a subprogram called .subprogram can also call another subprogram. When the main program calls a subprogram, it is regarded as a one-level subprogram call. Thus, subprogram calls can be nested up to two levels in this CNC system as show below:

One –level nesting

Subprogram

O2000； ... ... ... M98P3000; ... ... ... ... M99;

Two-level nesting

When the macro function is effective, the subprogram nested up to four levels. A single call command can repetitively call a subprogram up to 999 times.

1) Subprogram configuration

Format of a subprogram:

0□□□□; Subprogram number

……………………;

………………………..;

………………………

……

Subprogram

…… …… ……………………….;

………….. .;

M99 ; Subprogram end

A subprogram starts with a program number which consists of address O following by a-digit number and ends with M99 command. M99 can be specified in the same block with other command or specified separately as one block.

(Example) X……M99;

Note 1: For compatibility with other device, N□□□□ can be used at the start of a program instead of a subprogram number that follows O(:), the sequence number after N is registered as a subprogram number.

2) Subprogram execution

A subprogram can be called by a main program or another subprogram, the format of the call subprogram command is as below:

M98

Called Sub

Number of times the subprogram is called repeatedly

ram Number

When the number of times is omitted, the subprogram is called just one time. (Example) M98 P51002; This command specifies call the subprogram Number 1002 five times repeatedly. The subprogram calls command M98 P_can be specified in the same block with move command.

Same way as the main program calls a subprogram is used for a subprogram calls another subprogram.

Note 1: If the subprogram number specified by address P can not be found, alarm number PS078 will be output. Note 2: When Command M98 P0000 is input by MDI mode, the subprogram will not called.

3) Special Usage The following special method can be used in calling subprogram: If address P is used to specify the sequence number, control doses not return to the block after the calling block when the execution of a subprogram is finished, but returns to the block with the sequence number specified by address P. P code is not effective if the main program is operated in a mode other than the memory operation mode. This method takes much more time than the normal return method.

2.7.2 Program Number

Many programs can be registered in the memory of this CNC system. In order to identify one program from another, address O followed by a 4-digit number is specified at the beginning of each program registered in the memory.

O □□□□

Program number (1~9999,leading zero can be omitted)

Address O

A program starts by a program number and ends by command M30 or M99.

2.7.3 Sequence Number and Block

A program consists of several commands. One command unit is called a block. One block is separated from another with an End of block code. Notation “;”or “;” is used as an End of block code in this operation manual. At the head of a block, a sequence number consisting of address N followed by a number not longer than four digits can be specified. Sequence number may be specified in a random order and any numbers can be skipped. Sequence can be specified for all the block of a program or only for desired blocks of a program. For normal machining procedures, the sequence number should be arranged blocks in ascending order. It is convenient to specified sequence number for the blocks specifying important machining step (such as tool change or machining proceeds to a mew surface with table indexing).

Note: Because 0 can not be as program number, 0 must not be used for a sequence number for the reason of compatibility with program number.

2.7.4 Word and Address

Word is the basic of a block, a block consists of one or more words. A word consists of and address followed by a number (the plus sign (+) or minus sign (-)may be prefixed to a number).

X 1000

Address Number

Word

One of the letters A to Z can be used as an address. An address defines the meaning of a number that follows the address. The addresses and their meanings used in this system are as showed as the below table: Depending on the preparatory function, the same address may have deferent meanings.

2.7.5 Basic Addresses and Ranges of Command Values

Basic addresses and the ranges of values specified for the addresses are as follows. All these values are the limits of the CNC side, which are totally different from the limits of the machine tool side. For Example, the CNC allow a tool to traverse up to about 10 meter along the X axis, but for a machine tool, the actual stroke along the X axis may be limited to 2 meter. Similarly, the CNC allow a cutting Feedrate up to 15000mm per minute, but the machine may not allow cutting federate more than 4000mm per minute. When programming, the user should read the operation manual issued by the machine tool builder carefully as well as this manual to be familiar with the limits.

Table 2.7.5 Basic addresses and ranges of command values Function Address Input in mm Program number O 1~9999 Sequence number N 1~9999 Preparatory function G 0~99 Dimension word X,Z,U,W,I,K,A,R ±999.99mm Feed per minute F 1~~~500.00mm/rev Feed per revolution/lead of thread Spindle function S 0~9999 Tool function T 0~9932 Auxiliary function M 0~99 Dwell X,U,P 0~~~9999.999s Designation of program number or number of repetitions Sequence number P,Q 1~9999

Note: Actually, feed per revolution and the lead of thread are calculated into feed per minute depending on their relationship with spindle speed, and then restricted by the limit on feed per minute.

F 0~9999

P 1~9999

2.7.6 End of Program

By specifying one of the following codes at the end of a program to indicate the end of the program:

ELA ISO Meaning M30 CR M30 LF End of main program and return to the start of the program M99 CR M99 LF End of subprogram If one of the program end codes is encountered during the executing of a program, the control will stop the execution of the program and the reset state is set. When M30 CR or M30 LF is executed, control return to the start of the program (automatic mode). When the subprogram end code is executed, control will return to the program that calls this subprogram.

2.8 Coordinate Values and Dimensions

The following address can be specified with decimal point:

X, Z, U, W, R, A, K, I, F

2.8.3 Diameter Designation and Radius Designation

Since the cross section of the workpiece of lathe machine is usually circular, In CNC lathe control system programming, the dimensions can be specified in diameter and radius.

D1,D2 ..... Diameter Programming

R1,R2 ..... Radius programming

Z axi

X axis

When the diameter dimension value is specified, it is called diameter designation. When the radius dimension value is specified, if is called radius programming. Diameter or radius programming can be specified by parameter(ParameterNo.001BIT2=1). When using diameter designation, note the conditions listed in the below table:

Item Notes Z axis command No relation with diameter and radius X axis command Specified in diameter Incremental command U

Coordinate system setting(G50) Specifies a coordinate value of X axis in diameter Tool offset compensation value X component Cutting depth along X axis for command G90,G92 G94 Radius designation in circular interpolation(R, I, K ) Feedrate along X axis Change of radius/rev.

graduation indicates a diameter value in diameter programming and a radius value in radius programming. Note 2: When a diameter value is specified for the tool offset value, it indicates that when the outer diameter is cut by a new tool offset value changed by 10mm the otter diameter changed by a diameter value of 10mm. Note 3: When using a radius value for the tool offset value, the tool length itself can be set.

2.9 Tool Offset

Actually, the amounting position of tool used in machining a workpiece is different from the position of the standard tool used in programming. The different amount of distance between the standard tool and the actual tool (usually between the tool noses)is regarded as the tool offset value. In this system, tool offset is specified by T code; there is no G code to specify tool offset. There is only one types of tool offset can be specified in this system. Geometry offset.

2.9.1 Geometry Tool Offset

Standard tool

The task of a CNC program is made the tool nose of a standard tool to move along a specified path, It need all the tool to be mounted correctly to ensure the tool noses are at the same point as the standard tool. Actually, there is difference between the tool noses of the mounted tool and the standard tool, Geometry tool offset is used to compensate the difference when the tool actually used differs from the standard tool used in programming.

2.9.2 T Code for Tool offset

Meaning of T code:

T ○○ ○○

A) Tool Selection Tool selection is made by specified the T code corresponding to the tool number. Refer to the operation manual issued by the machine tool builder for the relationship between the tool selection number and the tool.

GUANGZHOU CNC EQUIPMENT CO., LTD.

GSK980T CNC SYSTEM USER MANUAL

B) Tool Offset Number

A tool offset number is used to select the tool offset value corresponding to the tool number that is selected to begin the offset function. Tool offset value must be input by keyboard. There are two offset amounts corresponding to one offset number, one X axis, one Z axis.

Offset number

01 02 03 … … …

When T code is specified and its offset number is not zero, the corresponding tool offset is effective. A tool offset number of 00 means that the tool offset is cancelled. Ranges of offset value: 0 to 999.999mm Diameter or radius designation can be selected for offset amount on X axis by setting Parameter No. 004: ORC

2.9.3 Tool Offset Value Input by Moving the Tool To a Fixed Point

When setting the tool offset value, press the [IN] key when an address(U, V, W) but not a number has been keyed in, the corresponding relative coordinate value is set as an offset value. This is used as following procedures to set the tool offset values conveniently:

(1) Move the tool tip of a standard tool to the standard point manually. (2)Reset the relative coordinate values U and W to 0. (3)Select the tool offset number of the standard tool. (4)Press [X] [O] [IN], and [Z] [O] [IN] to set the tool offset value of the standard tool to 0. (5)Move the tool to set an offset value to the standard point. (6)After selecting the tool offset number, the corresponding relative coordinate value will be set

as the desired offset value by pressing [U] or [X], and [W] or [Z] and then [IN].The different between the standard tool and the actual tool is indicated accordingly.

(7)Repeat procedures(5) and (6), offset value of other tool can be calculated and set

automatically.

Note: this input method is effective or not, depends on the setting of NOFC of Parameter No.010.

2.9.4 Direct Input of Tool Offset by Trial Cutting

To set an offset value, use the following convenient method. Suppose that a work coordinate system has been set according to a standard tool, move a actual tool to cut the surface A and B, input the measured values, the deference between the actual tool to cut the surface A and B, input the measured values, the deference between the actual tool and the standard tool will be calculated automatically and used as the offset value:

GUANGZHOU CNC EQUIPMENT CO., LTD.

GSK980T CNC SYSTEM USER MANUAL

Surface A

Surface B

(1)Setting the work coordinate system using a standard tool: (a)Cut surfaces A in manual mode with the standard tool. (b)Release the tool in X direction only, without moving Z axis and stop the spindle.

(c)Measure the distance βfrom the zero point of the workpiece coordinate system to surface A, select MDI mode, Press[PRG], key in: G50 Z “β”，Input this value as the desired X axis work coordinate value for current surface B, and set the address of this offset number(Standard tool offset number+ 100)Z=“β”.

(d)Cut surface B in manual mode with the standard tool. (e)Release the tool in Z direction only, without moving X axis and stop the spindle.

(f)Measure distance α, select MDI mode, Press[PRG], key in:G50 X“α”,Input this value as the desired X axis work coordinate value for current surface B, and the address of this offset number (Standard tool offset Number=100) X=“α”

(2) Offset value input of non-standard tool (a)Cut surface A in manual mode with the this desired tool. (b)Release the tool in X direction only, without moving Z axis and stop the spindle.

(c)Measure the distance“β”from the zero point of the workpiece coordinate system to surface A, and the input this value as a measured value data for Z axis in the desire tool offset number, this address of this offset number satisfies:

Address of offset number =the desired offset number+100

(d)Cut surface B in manual mode (e)Release the tool in Z direction only, without moving X axis and stop the spindle.

(f)Measure the distance“α”,input this value to address X, this address=the desired tool offset number+100.

Example: in order to set the offset value to the address corresponding to offset number 03, the measured values“α”and “β”should be set to address 103. If the coordinate value on surface B is 105.00,and the measured value is 104.00, the setting value of address should be 104.0, and the offset value corresponding to offset number is set to 1.0 automatically.

(3)Repeat the procedures (2) to set the offset value of other tools.

Note1: Direct input of the tool offset value is effective when the parameter DOFS(parameter No.12) is 1. Note 2: Distance“α”is always measured in terms of diameter.

2.10 Automatic Acceleration and Deceleration

Acceleration/deceleration is automatically applied at the start/end of a tool movement to prevent a mechanical shock, resulting in smooth start and stop of movement. Automatic acceleration/deceleration is also applied when federate change, so the change of speed is also smooth. Rapid traverse: Linear type acceleration/deceleration (Time constant is set by parameter common to all axis ) (parameter No.029) Jog feed: Exponential acceleration/deceleration(time constant is set by parameter common to all axis) (parameter No.029)

2.10.1 Speed Control In the Corner Between Blocks

As automatic acceleration and deceleration being adopted after interpolation, arcs will appear in the corner between blocks during cutting. a quasi-stopping command（G04）can be inserted to cancel these arcs. For example：there is one motion only in X axis in one block and another motion in Z axis in the other block. During the deceleration in X axis, acceleration being done in Z axis, then the trace of tool is below：

If a quasi-stopping command being inserted, the tool will move along the solid line above according to command. Otherwise, larger the cutting speed is or larger the time-constant in acc&dec is, larger the radian of the corner. In G02 or G03 command, the radius of actual tool trace is shorter than that specified in block. In order to reduce the error, the time constant should be smaller to the best under permission in machine system.

Note: The following disposal will be adopted in CNC between blocks

2.11 The Macro Program to User

Store some function realized by a set of dictate to memory as a subprogram and use a command to stand for this function, which can be transferred in program. This set of dictate is called the macro

program body, sometime being called macro program. The corresponding command is called “macro command to user”,sometime being called transferring command.

GUANGZHOU CNC EQUIPMENT CO., LTD.

GSK980T CNC SYSTEM USER MANUAL

The programmer only need to remember the macro command, not the body of the macro program. The greatest characteristic is using variable in the macro program body, which can be in operation and evaluation.

2.11.1 The Macro Command

Format :M98 P□□□□；

Use the above command to call the macro program body specified by P.

Program number of the macro program body being called

2.11.2 The Macro Program Body

General CNC dictate and variable, operation ,transfer dictate are usable in the macro program body, which being started with the program number following O and ended with M99.

（1） The using method of variable

Address in the macro program can be specified by variable. The variable value can be specified by evaluation in main program or setting in keyboard, or by evaluation in calculating during doing macro program body. Several variable can be used, which is differentiated by variable number. （a） expression of variable

symbol“#”is to express variable, the format is following： #i（I=200,202,203,204……）

Eg.#205,#209,#1005 （b） citation of variable variable can replace the value of address If there is <address>#I or <address>-#I ,then the positive or negative value of variable is taken as address value. Eg.F#203…if #203=15,it’s same as F15. Z-#210…if #210-250,it’s same as Z-250. G#230…if #230=3,it’s same as G3. When taking variable to replace variable number, not ##200, but #9200 is used, that is “9”behind # meaning replacing variable number. For example:

O8000； G65 H01……； G00 X#101……；
