INTRODUCTION.

FANUC Offline software is a very powerful Educational and Industrial system. In Education students can learn to program GNG Machine Tools at the computer and prove the program through an animated graphical simulation of the cutter path. In Industry the ability to prove out Gnc part programs away from the machine in a clean and quiet environment and store programs on Disk media has many obvious advantages. The GNG Desk Top Tutor overcomes problems offering true M.D.I. programmimg at the computer.

OFFLINE PROGRAMMING

1.5 MACHINE LINK CONFIGURATION

The link to the enc Machine Tool depends on which controller has been fitted. Denford's provide a selection of controls to cover different levels of Training and Industry. To communicate to any controller there needs to be a physical connection between the computer and the control. This is done through the RS232 serial port.

COMPUTER SERIAL PORTS.

Computers can have several serial ports attached: Located at the rear of the computer a serial port can be either a 25pin or 9pin type. Some computers have one of each type. Serial ports are assigned a name (COM1 or COM2): You need to decide which port you will be using for communicating to the controller.

We supply cables already configured. All you need to do is to plug them into the computer and the controller. If you want to make your own cables because of distance or you require a 25pin - 9pin converter. Details of how to do this can be found in the cables section of this manual.

OFFLINE PROGRAMMING

11

CNC CONTROLLER SERIAL PORTS

The connection can differ between 7pin din plugs to 25pin serial connectors. Your Machine Manual will have more information on the control. Some controls need to be configured correctly, although this will probably have been done by Denford's. If you can't find the relevant information in your machine manual contact Denford's hotHne support team who will be glad to

help.

HOW HELP SCREENS WORK The Help file contains different types of information, to locate a particular entry you need to understand the structure of the Help file.

HELP FILE STRUCTUlRE

Comments Example (This is a comment Comments start with an open brack.et and can be inserted anywhere in the Help file. They are ignored by the compiler and are only to help the end user document the Help file. Page Start Example IHELP PAGE1 AI Example IG and M Code 'Errors I

Each Page Start begins with a tramline character followed by the Page name. Actual Help Pages have a page designated by a letter from A to Z. A page start can be a) Help section. b) Error section. c) Information. Important It is vital that the pages relating to error messages, fast key strips and text that are used directly by the software are not altered. The software relies on each line being in sequence. Help screens that are used with the F1 key can be placed anywhere, but we suggest you put them at the end of the program.

CONTEXT SENSITIVE HELP

HOW IT WORKS

To insert a new Help Page you first decide what type of help aAd where the help should be placed. For example we might like a lesson on Cnc programming to be available by pressing the F1 key during edit mode. At the moment pressing the F1 key during edit may display the paragraph below. EDIT AND SIMULATE You are now editing a CNC program. A variety of instructions can be keyed in on each line. At any time you can start a simulation of the machining of your program via the F9 m':3nu.

Whilst typing, characters will appear at the cursor position. The cursor is the flashing underscore or the steady blob. EDIT KEYS eNC INSTRUCTIONS

How to add a Cnc lesson as a sub menu: 1 - We decide what the menu option should be called, in this case we shall call it "Cnc Lessons".

2 - A name for the Help Page we want to display when we select Cnc Lessons. In this case LESSON1.

3 - Load the Help File into the Cnc Editor and locate the Help page displayed above. You will find the start of the page near to line 676, The page start is IEDIT AND SIMULATE I which is called up by pressing F1 when in the Edit and Simulate Mode. 4 - At the bottom of the Help Text you will see the sub menu's being referenced.

, 5 - Add #Cnc Lessons#LESSON1 A to the list

72

OFFLINE PROGRAMMING

6 ~ Go to the end of the file to write the Help screen for LESSON 1. 7 - Type I LESSON1 AI this is the start of Lesson1 and the page number is 'A'. Always use capital letters for Page Starts. 8 - On the next line write a titre for the Help Screen, try enc lesson One. 9 - Now you can write the actual text making sure the lines are no longer than 47 characters. 10 - If you want more room for the enc Lesson you can start a new page by typing I LESSON1 B I enc Lesson one Page 2 Followed by the Text. 11 - If you want sub~menu's to be displayed on your new Help page simply place the referencing commands at the bottom of the Help Page. Example #G and M code#HELP PAGE1 A 12 - Upon completion save the new Help File and compile to Disk. Run the software to test the changes. Good luck!.

CONNECTION PROCEDURE

Before running the Desk top version Offline programming software, the Desk Top Tutor must first be connected to the computer. CONNECTION PROCEDURE

The connection from the serial port of the computer to the Desk Top Tutor is via the cable provided. This cable is a 1 metre ribon type cable with a 25 way D type female connector at either end. Note: if the user's computer has a 9 pin serisl port then a 25 to 9 pin converter will need to be constructed or purchased from Denford machine tools (See cables section - section 1 for cable information ). Once the Tutor is connected to the computer, the qwerty keyboard becomes non-functional. To return to the qwerty keyboard then: Press ext/keybd.

3.1 WORD DETAILS

Although the Control will, in general, accept part programming words in any sequence, it is recommended that the word order for each block is used:. N.G. X or U.Z or W.I.K.F.S.T.M.

0: Program Number The : followed by a 4 digit numerical value is used to assign a program number. N : Sequence Number The N word may be omitted. When programmed, the sequence number following the N address is a four digit numerical value and is used to identify a complete block of information. Although ascending, decending, or duplicate numbering is allowed, it is best to program in ascending order in increments of 10. This allows for future editing and simplified sequence number search. ~

Preparatory Command The two digit G command is programmed to set up the control to pertorm an automatic machine operation. A full list of G codes are given. One G word from each modal group and one non modal G word can be programmed on the same block. G

EXAMPLE:

Valid N100 GOO G40 G90 G95 Nonvalid N100 GOO G4Q G41 G90 G95

.840 & 841 are from the same group. A retained G word (Modal) from one group remains active until another 8 word from the same group is programmed. One-shot G words (Non-Modal) must be programmed in every block when required.

NOTES FOR G CODE LISTING

Note 1:

G Codes of 00 group represent those non modular and are effective to the designated block. Note 2:

G Codes of differerlt groups can be commanded to the same block. If more than one G codes from the same group are commanded, the later becomes effective.

AxiS Definitions:

Z Axis

The Z axis is along a line between the spindle and the tailstock or the centre line of rotation of the spindle. Minus (-) movements of the turret are left toward the headstock; positive (+) movements are right toward the tailstock.

X Axis The X axis is 90 degrees from the Z axis (perpendicular to the Z axis). Minus (-) movements of tbe turret are toward the centre line of rotation, and positive (+) movements are away from the centre line of rotation. X : X Axis Command

The X word is programmed as a diameter which is used to command a change in position perpendicular to the spindle centreline. U : X Axis Command The U word is an incremental distance (diameter value) which is used to command a change in position perpendicular to the spindle centre line. The movement is the programmed value. Z : Z Axis Command The Z word is an absolute dimension which is used to command a change in position parallel to the spindle centreline. W : Z Axis Command The W word is an incremental distance which is used to command a change of position parallel to the spindle centreline.

Do not program X & U or Z & W in the same block. If an X axis command calls for no movement it may be omitted.

x JU

or P : Dwell The X word is used with G04 to command a dwell in seconds.

I WORD

a) G40 active

For arc programming (G02 or G03) the I value (With sign) is programmed to define the incremental distance parallel with the X axis between the cutter centre and the component arc centre at the start of arc.

92

OFPUNEPROGRAMMING

(

b) G41/G42 Active For arc progranming (G02 or G03) the I value (With sign) is programmed to define the incremental distance parallel to the X axis between the start of the arc and the arc centre. c) Used in automatic cycles KWORD

a) G40 Active For arc programming (802 or G03) the K value (with sign) is programmed to define the incremental distance parallel with The Z axis between the cutter centre and the component arc centre at the start of arc.

b) G41/G42 AcUve For arc programming (G02 or G03 ) the K value (with sign) is programmed to define the incremental distance parallel to the Z axis between the start of the arc and the arc centre. c) Used in automatic cycJes. The maximum arc for I & K programming is limited to the quadrant. If I or K is zero it must be omitted. FWORD

a) In G99 mode the F word is used to command feed/rev. b) In G98 mode the F word is lJsed to command feed/min. c) In G32 mode the F word specifies the lead' of the thread.

P WORD

a) Used in automatic cycles to define the first block of the contour. See Section 5.5 b) Used with G10 to define the offset number in the tool geometry file. c) Used to define a subroutine number.

OFFllNE PROGRAMMING

93

aWORD

Used in automatic cycles to define the last block of the contour. See section 5.5 RWORD

a) For circular interpolation (G02 or G03) the arc radius is to the centre of the tool nose radius (G40 active) ~ or the actual radius required (G41/G42 active). b) The R word is programmed with G10 to indicate the tool radius in the tool geometry/wear file for use with work surface programming (G41/G42). SWORD

a) In the constant surface speed mode (G96) the four digit S word is used to command the required surface speed in either feet or metres per minute. b) In the direct r.p.m. mode (G97) the four digit S word is used to command a finite number of spindle speeds in r.p.m. increments between the ranges available for the machine (see Machine Specification). c) Prior to entering the constant surface speed mode (G96) the S word is used to specify a speed constraint, the maximum speed allowable in the current gear range, or less, to prevent the spindle overspeeding. To command this restraint the S word is programmed in conjunction with the G50 word only. TWORD

Tool words are used to cause a tool change, and to activate tool geometry offsets to obtain the desired machining accuracy. The first two digits in the T word (01-16 depending on the

number of tool stations) are used to describe a turret station number.

The third and forth digits of the T word are used to activate a pair of offsets (01-16) that allow the operator to compensate for tool wear, tool length deviations, and tool deflections. The pair of offsets consists of one for X axis compensation and the other for Z axis compensation. These initial values are based on the incremental distance with sign from the tool tip to the turret datum. For the X value only the value is doubled (diameter programming). Programming 00 for these two digits cancels the tool offset.
