1.1The system's description

The C-502 is a computerized turning machine system for sliver processing plastic, hard wood and soft metal products. The system enables us to manufacture products from these materials. The system includes a spindle motor operated by a DC motor.

The processed material is tightened into the spindle bore. The turning tool is installed on a table, which moves on two axes (X and Z).

The processed material is a round rod that rotates and the turning tool movement on X direction cuts it on its perimeter.

The turning tool movement on Z direction is along the rod.

The movement of each axis is done by a DC motor, which includes a magnetic encoder with hall effect sensors. The encoder outputs pulses according to the motor's rotation.

The system is located inside a metal structure with a transparent door in the front. The door operates a magnetic switch when it is closed.

The system includes a computerized control unit. The control unit operates the motors, receives the pulses from the encoders and operates the DC motor of the spindle. The system stops each time the front door is opened.

A computerized system for sliver processing is called CNC (Computerized Numeric Control). The system's controller receives data, which determine the movement of the turning tool (location and speed) and moves it accordingly in a controlled manner.

A special language was created for CNC machines called G&M-Code. This language is a universal language and despite this, each machine has its own unique commands. This book describes the C-502 command set and the system's programming method.

The programming language enables us to create programming files, where each file is designated to manufacture a certain product (or part). The files are saved in the computer's disk. In this way, we can manufacture a certain part in the same level of accuracy and unity at each manufacturing, even if the first manufacturing was a long time ago.

The CNC system enables us to manufacture the exact amount of products we need. All it takes is to load the computer with the appropriate file and run the program. This process turned the manufacturing significantly flexible. Flexibility means an easy transfer from one product to another. These machines are called FMS (Flexible Manufacturing Systems).

The C-502 system is accompanied with the S-LATHE software. This software enables us to create and edit a G&M-Code file and run it.

Running the file can be done in two ways by simulation or by operating the machine.

In the simulation method, the software draws the turning tool movement on the screen.

In the machine operation method, the computer sends a movement commands to the system's control unit and the control unit executes the processing.1.2G&M-Code language

The G-Code language is a very simple programming language and this is the secret of its popularity.

The programming file is a text file written by a text editor (a simple word processing).

The programming rules are as follows:

Every instruction to the machine should start with the letter G or M (this is the reason for the name G&M-Code).

The software ignores lines that do not start with the letter G or M.

For example, G1 X10 Z-35 F250 meaning:

Move in straight line (on X-Z plane) to point X, Z = 10,-35 from the current location at feed of 250 millimeters per minute.

All the parameters should be given in millimeters.

S-LATHE software allows using the decimal point. i.e.: G1 X10.5 Z20.7Important Note

S-LATHE uses point as decimal point. Computers that are set to comma as decimal point must be changed to point as decimal point. It is done in the 'Regional and language options' on the 'Control Panel'.

The parameters are optional. It means that the current value of a parameter that is not indicated in an instruction remains without change.

We use the '/' sign to indicate relative values.

i.e.: G1 X/7.3 Z/-5 which means:

move 7.3 millimeters forward on X and 5 millimeters backward on Z from the current location at previous feed.

The S-LATHE G-Code instruction set:1) G0 Xxx Zzz: Idle movement on straight line (in a Cartesic axes system) to point xx,zz at maximum speed.

Examples:

G0 X2 Z-30

G0 Z15.2

2) G1 Xxx Zzz Fff:

Turning movement on straight line (in a Cartesic axes system) to point xx,zz at ff speed.

Examples:

G1 X1 Z-30

G1 Z15.2

3) G10 Rrr Ccc Iii Kkk:

Idle movement on straight line (in a Polar axes system) to point on a circle's perimeter at maximum speed.

R is the circle radius.

C is the angle (in degrees) of the point.

I and K are the X,Z coordinates of the center of the circle.

Examples:

G10 R10 C30 I25 K20

G10 C180

4) G11 Rrr Ccc Iii Kkk Fff:

Turning movement on straight line (in a Polar axes system) to point on a circle's perimeter at ff speed.


C is the angle of the point.

I and K are the X,Z coordinates of the center of the circle.

Examples:

G11 R10 C30 I25 K20 F2000

G11 C180

5) G02 Iii Kkk Rrr Ccc Eee Fff: Clockwise turning circular movement (arch) at ff feed.


C is the angle (in degrees) of the starting point.

E is the angle (in degrees) of the ending point.

Note:

The instruction G02 means move in a straight line to the arch starting point (indicated by C) and then to the arch ending point (indicated by E).

Examples:

G1 X-5

G1 Z-30

G2 K-30 I-6 C90 E0 R1

G2 Z2 X-6

6) G03 Iii Kkk Rrr Ccc Eee Fff:

Counter clockwise turning circular movement (arch) at ff feed.

Examples:

G1 X-5

G1 Z-30

G3 I-5 K-31 C180 E220 R1 F150

G3 Z2 X-6

7) G4:"Wait" instruction, usually applied for stopping in order to replace the turning tool or the processed material.

A message appears on the screen and the PC waits for clicking OK to continue.

M-Code instruction set:

1) M4 Sss - Command to start the spindle Motor CCW at ss speed in RPM.

2) M5 - Command to stop the spindle Motor.

1.3Installing the S-LATHE software

The S-LATHE is a WINDOWS application turning program.

1) Turn ON the PC.

2) Using "My Computer" functions, copy the S-LATHE sub-directory from the diskette to the hard disk.

3) Create a short-cut to the software S-LATHE.exe, which is in the S-LATHE sub-directory.

4) Move this short-cut to the desktop window.

To run the S-LATHE software you have to double click over this icon.

1.4Operating the system

The C-502 power supply is an external power supply that supplies low DC voltage to the C-502 controller. The C-502 controller communicates with the PC in serial communication (RS232 or USB).

The power supply is connected to the C-502 by two wires.

The C-5021 controller communication socket and RST pushbutton are located on the right panel.

Step 1:Connect the red wire to the + (red) terminal of the power supply.

Connect the red and black wire to the (black) terminal of the power supply.

Step 2:The serial communication cable (CBL-1) is a 3 wire cable with a D-connector on one side and an earphone plug on the other side.

Connect the D-connector to the serial communication outlet of the PC (COM1 or COM2) and the earphone plug to the earphone inlet.

Experiment 1.1 Turning Processing

Objectives:

Writing the first turning program according to a drawing.

Understanding turning processing.

Running the program on simulation.

Equipment required:

PC computer

S-LATHE software

Discussion:

In turning we have several processing types: Turning, Grooving and Threading.

The processed material (a rod of metal, plastic or wood) is installed in the spindle bore and rotates fast.

When the turning tool goes on Z dimension, it removes slivers from the perimeter of the rod (like peeling).

The turning tool speed on Z direction should not be faster than the spindle rotation.

When the Z movement is faster than the spindle rotation we get a thread.

When the turning tool goes on X direction only into the rod, it creates a groove along its perimeter.

The turning drawing shows only half of the part projection. This is enough because of the complete symmetry. The drawing includes a symmetry axis.

In the experiments that follow we will process the part shown in the following figure.

Figure 1-1

The symbol indicates the project home position. It is also the origin of the axes. The X,Z absolute values relate to this point.

The numbers a he right show the distance from the home project on X axis.

The processing process is done by turning one millimeter at a time as described in the figure 1-1.

With a special turning tool and on grooving process we cut off the required processed material from its base. The rod is cut when the groove depth is equal to the rod's radius.

We define the starting point outside the main material.

We turn an extra part in front of the required processing area. This part is called 'Face' or 'Forehead'.

Usually, we use a rod with a diameter greater than required and we turn it to the required diameter, in order to ensure straight and symmetrical rod.

In this experiment we will turn a 20 mm rod into 18 mm rod above the cut off position. This also processes area No. 1.

Important note:

Because the setup of the turning tool can be done only on the unprocessed rod, we will run the program on simulation until we have a complete turning program.

Warning:

Dont cut more than 1mm each time.

Cutting more than 1mm can brake the tool or jam the machine.

Procedure:


An introductory screen will appear on the screen.

Step 2:Select the FILE function and the NEW sub-function.

An editor window appears and more functions are added to the menu line.

The added functions are EDIT, VIEW, and RUN.

Step 3:Type the following G&M-Code turning program for range 1:

M4S2000;start spindle motor at 2000 RPM

G0X-9; range 1move to 9mm from the rod center

G1Z-66 F200;move to point 2

G1X-10 Z-70;move to point 1

G0Z0;return

M5;stop spindle motor

Step 4:Compare the program with the drawing. Check each instruction.

Step 5:Select the function FILE and the SAVE AS sub-function.

A dialog window is opened requesting the file name.

Step 6:Type the name PART1 and click OK.

The program is saved under the name PART1.TAP.


Select the SIMULATION sub-function.

In simulation mode, the software simulates the machine behavior on the screen, without processing the material.

This option enables us to check our program before turning the material.

Step 8:Select the function RUN and the RUN sub-function.

A graph window appears.

The program is executed step by step graphically on the window.

Observe the drawing.

Step 9:If the graph is not correct according to the program, correct the program and run it again.

Step 10:Add to the program the instruction for range No. 2.





G0Z0;return


G1Z-38;move to point 4


G0X-10;move out

G0Z0;return



Step 12:Select the FILE function and the SAVE sub-function or click [Ctrl+S] for saving the program.






Experiment 1.2 Arches

Objectives:

Understanding arch programming.

Understanding arch processing.

Equipment required:

PC computer

S-LATHE software

Discussion:

An arch is part of a circle. To define an arch we define the center of its circle and the starting point on the circle's perimeter (see the description of G2 and G3 instructions).

Figure 1-2

Area No.3 includes an arch and its center is at points X=-8 and Z=-36. Check that.

Because the radius of the arch is 2mm only, we will process the arch in two stages.

The arch at the first stage is from 150o to 180o.

Figure 1-3

The arch at the second stage is from 150o to 90o.

Figure 1-4

The second arch at range 6 has 4mm radius. We shall divide the arch to 4 stages.

Figure 1-5

The angles are: 14.5o, 30o, 48.6o and 90o.

The arch at the first stage is from C = -48.6o to E = -90o.

Figure 1-6

The arch at the second stage is from C = -30o to E = -48.6o.

Figure 1-7

The arch at the third stage is from C = -14.5o to E = -30o.

Figure 1-8

The arch at the fourth stage is from C = 0o to E = -14.5o.
