Programming Instructions

Preliminary remark

The present manual refers to the "Z25 NJ" software version of the CC 220/320 M control.

NOTE!

Information on the current software version of ’your’ control can be found in the DIAGNOSTIC group operating mode after pressing the DIAGNOSTIC CONTROL and SOFTWARE VERSION softkeys.

It contains − with regard to the manual title − the information required for the proper operation of the control. For reasons of clarity, however, it does not contain all details of all possible function combinations. Likewise, since the control is as a rule a part of larger installations or systems, it is not possible to cover any imaginable case of integration or operation.

If, however, you should wish to get further, more detailed informtion, or in case if special problems occur in the operation of the control which are not, or not detailed enough, covered in this manual, please address your questions to your local Bosch service department or to our customer consultation department.

The present description does only apply to DIN programming of the CNC. For CPL programming, a separate manual is available. For programming the machine−tool manufacturer cycles, please observe the corresponding description of the machine−tool manufacturer.

Programming the control allows you to influence the axis movements (e.g. positions etc.), machining technology (e.g. feed, rpm, etc.), machining sequence (e.g. tool change, compensation, help−function output, etc.), and even the interaction between CNC and drives (e.g. KV programming). All this requires general programming knowledge on the one hand (e.g. for the logic program sequence, the description of the contour, etc.), and on the other hand knowledge of the technology of CNC lathe−turning/milling (e.g. for the selection of the correct feedrate for machining a certain material).

Therefore, programming must only be performed by correspondingly trained personnel.

CAUTION!

Programming by insufficiently or even untrained, or unexperienced, personnel

!may result in severe damage to machines, drives, tools, workpieces or even bodily injury!

Test the programs first without axis movement! The control provides for such tests

!the TEST ON softkey in the AUTOMATIC (NC) group operating mode. If this softkey is displayed in inverse video, no movements directly initiated by a part program will be performed.

BOSCH excludes any liability for subsequent damage resulting from processing

!an NC or CPL program or of an individual block, or from manual traverse of the axes! And neither will BOSCH be liable for subsequent damage which could have been avoided by appropriate PLC programming!

Please note in this context our extensive training offer. An seminar overview can be found on the inside of the manual’s cover sheet. For details, please contact our training center (Telephone: −6062/78258).

Definitions

System of coordinates

The explanations contained in these instructions follow DIN 66217. This standard standardizes the direction and arrangement of the coordinate axes.

The coordinate system used is a right−handed, right−angled system with X, Y and Z axis.

+Z

+X

+Y

Axis identification

The coordinate system is correlated in relation to the working spindle to which the Z axis runs in parallel. Positive axis direction runs from the workpiece to the tool. The X axis is parallel to the tool clamping surface and horizontal. X and Z define the location of the Y axis.

Further independently controlled axes, arranged in parallel to the main axes, are referred to as U, V, W. Rotary movements performed by machine components around the main axes (e.g. rotary axis) are referred to as A, B, C.

Programming Instructions

After power−up, the CNC requires an electric signal indicating the accurate posi tion of each axis. This signal is provided by adjustable cam switches. The indicated

position is referred to as reference point (R) and identified as follows:

R

The position of the reference point of each axis is measured exactly from the ma chine zero point, and its position is memorized in the CNC.

In these instructions, all axis movements are represented as a relative movement of the tool.

In this context, the diameter and length of the tool are generally not considered. The position of the tool on the programmed path corresponds to the

tool set point (N) and is identified as follows:

Fundamentals

Essentially, programming CNC controls defines the following processes:

‘Workpiece machining

‘Tool selection and change

‘Workpiece change

‘Workpiece and tool measurement.

For these definitions the CC 220/320 M features two programming options:

‘According to DIN 66025

‘CPL

Except for the drilling cycles, this manual covers programming according to DIN 66025 only. Machining is its major subject. Tool and pallet changes are machine− dependent cycles, and are not discussed here.

Part programs can be created as follows:

‘Directly on the panel of the machine via the standard arithmetic keypad or optional ASCII keyboard

‘In office−based programming stations

Programming Instructions

Program structure

The program represents a sequence of machining steps and is divided into blocks.

These blocks contain preparatory functions, path information, auxiliary and supplementary functions. They provide information on:

‘the position

‘the technology

‘the program sequence

The number of programs is only limited by the available memory space.

Program start

During reading in, the first character of a program has to be an end−of−block character. This allows the control to recognize the start of a program. The pro gramming code (EIA/ISO) will be determined as a function of the parity of this first end−of−block character:

‘Even parity = ISO code (8 bits incl. even parity)

‘Odd parity = EIA code (8 bits incl. odd parity)

ISO and EIA code tables can be found in the annex to these instructions.

NOTE!

All characters programmed before the first end−of−block character will be ig nored by the control during data in.

Program sequence

Without corresponding program instructions the program blocks will be executed one after the other. However, it is possible to influence the program sequence using the following options:

‘Subroutine calls

‘Repeat instructions

‘Jump instructions

‘"Block slash" function

End of program

The end of program is identified by

‘M30 and end−of−block character or

‘M02 and end−of−block character or

‘M2 and end−of−block character.

The effects of M02, M2 and M30 are absolutely identical.

Apart from M02, M2 or M30, no other information may be contained in the last pro gram block. M02/M2/M30 always sets power−up state except in the case of G14/G15 and G70/G71.

At the end of subroutines, M02/M2/M30 causes only a return to the calling pro gram.

Program block

A block is made up of the block address, one or more words, and the end−of− block character.

The end−of−block character must always be written (ISO code: LF, EIA code: CR), but will not be displayed. The blocks may be of different length, but are limited to 128 characters per block. The block address forms the beginning of the block. As a principle, more than one G or M words are allowed within one block. The block address and the words may be preceded by "BLANK" and "TAB" special charac ters.However, programming "BLANKs" and "TABs" requires a lot of memory space and furthermore prolongs the block cycle time.

If a slash is programmed ahead of the block address (e.g. "/N100"), this block may be skipped during the program sequence. For this purpose the "/BLOCK SLASH" function in the "NC" group operating mode or the related interface signal must be activated (also see CC 220/320 Operating instructions, chapter 6: "Program−se quence interventions" and Interface conditions, chapter 5.1.: "Inputs of the con trol").

Example:

/ N100 G1 X255.3 Y−3240 Z20.78 F600 LF

ID

Block address

Words

End−of−block character

The block numbers should be programmed in ascending sequence. It is recom mended to avoid gaps in this sequence.

When editing the program later, up to 99 additional blocks can be inserted between two individual blocks.

Example:

N1
N1.1
.
.	may be inserted
.
N1.99

NOTE!

When omitting the block address the program’s readability and flexibility (jump commands) becomes worse, but the block cycle time is slightly improved.

Program word

A word is made up of the address letter, the sign and a numerical string. A posi tive sign can be omitted during input. Depending on the format (integer/real), the numerical string may contain a decimal point. Within the defined limits, words of any length can be programmed. It will, however, suffice to indicate only those nu merals actually containing information.

Files

The systems contains several file groups:

P:Part programs, CPL, dialog programs

K:Compensation tables

V:Zero offset tables

W:Communication store tables

G:Graphic files (presently not used)

D:Diagnostic programs

L:System files

S:PLC programs (PIC 200)

For workpiece programming (application), the first 5 of the file groups mentioned are of relevance.

With regard to the file groups, the system does not distinguish between main pro grams and subroutines or cycles, respectively. All 3 program types are identified by the P file group. It is thus possible to call up an existing main program as a subrou tine.

NOTE!

The display of individual blocks of subroutines can be suppressed in the "EXECU TION" operating mode. To do so, the read protection (cancel R) has to be activated using a softkey.

The D, L, S file groups are special files and subject to special rules.

If a file with the T identification is being read in, the CNC will display its contents only on the screen. The file will not be taken over into the part program memory.

File header

Each file has to contain a defined file header, the so−called DFS identification. This makes it, i.a., possible to protect files from unauthorized access. The file header has to be preceded by an end−of−block character or STX.

Format of the DFS identification:

(DFS, P 123456789, TEXT, R W E D)

File protection

File name (30 characters max.)

File number (9 characters max.)

File group identification

Comma, ")" and LF are not allowed in the file name. File name and file protection do not have to be specified. If the file protection is missing in the DFS identification, standard "RWED" will be defaulted.

Notes on files

Leadscrew error compensation

The values determined by a laser interferometer are a function of the machine or axis, and can be permanently stored in the CNC system (EEPROM).

The data is stored in the L files L100 to L108 (1st to 8th axis).

Machine parameters

For editing machine parameters, an L file, L444, is created in the part program memory; however, after editing, this file will be deleted again (refer to the "CC 320 Machine Parameters" manual, P.−No. 4180).

E code

The "E code" option can be used to increase the reliability of reading in data from external media into the program memory (for a description, please refer to pages 5−6).

OPERATION

Program selection

When selecting a program − manually or externally, a linkage run is started, and a link table is created. This link table is used to perform jump addresses to various subroutines, calculations, etc., which are no longer to be executed during the ex ecution of the program.

This speeds up the program run.

The link tables are listed under "GOM AUTOMATIC" (ref. to the CC 220/320 M oper ating manual, P.−No. 4181).

Link tables are assigned to the L1 to L99 range. They can be deleted or permanent ly stored (in this case the linkage run prior to program execution will be omitted). It is furthermore possible to create link tables in advance. In this case, the linked program will not be selected after the end of linkage (background linkage).

Automatic deletion of programs and tables

Using the CLM command it is possible to automatically delete part programs, zero offset tables or compensation tables prior to reading in new programs.

(CLM, P...) (CLM, V...) (CLM, K...)

Delete part program Delete zero offset table Delete compensation table

The LF (Line Feed) character has to precede the bracket expression. More than one CLM commands can be programmed in series.

Leader programming

An identification text (e.g. in the case of punched tape) can be programmed as a leader for the actual part program.

The leader text may be of any length. No end−of−block character must be pro grammed (within the leader). In this way the text will be ignored by the CNC and will not be displayed.

The first end−of−block character (LF) makes the CNC automatically recognize the code format (EIA/ISO). LF or STX sets the code format to ISO. Subsequently, a DFS identification is expected from the CNC.

Prompt programming (Prompts before read−in of the program)

Applications

Prompts for the operator, before one or more programs are read in. In the case of more than one program stored on one and the same storage medium, in order to permit a table of contents to be displayed.

If only a single text is to be displayed, the leader of the file containing the text has to be written as follows:

(DFS, T) <CR> <LF>

.

.
.	Text
.
.

<CR> <LF> M30 <CR> <LF>

Alternatively, T can be programmed with a number (e.g. DFS, T10) in order to dis tinguish between several "text files" on one and the same storage medium.

18 lines with 64 characters each are available on the screen for text. Individual lines are automatically separated after 64 characters (even within one word) or at a point defined by the end−of−block character (LF).

If M30 is detected, reading−in is stopped, and the programmed text (e.g. with op erating instructions for a part program) is displayed. The text will not be taken over into the program memory of the CNC.

Reading−in of the actual program can be restarted using a softkey. The display appears only in the program−memory mode. It will be deleted in case of a mode change and will not appear again, even if the same operating mode is selected again.

NOTE!

The combination of the M30 and end−of−block characters must not occur within the text. A programmed end−of−block character will not cause any display.

A gap of 110 <NUL> characters must be between the text and the following file.
