Siemens 840D user guide: 6 "Program" operating area 6.8 Program simulation 01/2008 6

6 "Program" operating area 6.8 Program simulation 01/2008 6

Additional information

1. Changes to the blank dimensions in the infeed axis (min or max) are automatically traced in the depths for color separation (min or max).

2. High values for the interpolator approximation accuracy cause increased distortion of the geometry representation (e.g. in details and rounded sections), but also reduce the amount of graphics memory required and increase the speed of the simulation.

Recommended settings

3. Recommended setting for group "simulation mode":

   • .. in production
     • Always reload tool "off" and store tool path "off"
     • Block by block preparation "on" and wait with dwell times "off"
   • .. in program mode (default setting)
     • Always reload tool "on" and store tool path "on"
     • Block by block preparation "off" and wait with dwell times "off"
   • .. In training operation
     • Always reload tool "on" and store tool path "on"
     • Block by block preparation "off" and wait with dwell times "on"

4. The following settings are recommended for demonstrations with endless program loops (accelerated execution of simulation with reduced demands on the graphic memory):

   • Always reload tool "off" and store tool path "off"
   • Block by block preparation "on" and wait with dwell times "off"

and additionally:

• Blank "without model" (no memory used for graphic!)
• Or "without tool data", if representation of the tool center-point path (broken-line graphics) is sufficient.

If the blank model is active ("cuboid", "cylinder"), reduced graphic memory capacity might result, which, depending on the complexity of the part and model resolution set, could exhaust the graphic memory despite the save tool path setting "OFF".

6.8.3 Setting downtimes

Timing mode Setting timing for downtimes:

Settings. Downtime settings

OFF (default setting) Central timing does not include fixed downtimes or the processing of information for tabular "Time analysis".

Per program Central timing includes the elements listed in "Inclusion on" in the downtime analysis. The tabular "Time computation" is processed once per program in each case with M30, for example.

Per section with labels Effect as for "per program", only that processing of the tabular "time computation" is also performed when freely definable program labels occur or in combination with the path labels displayed in the simulation graphic (see ..\ Display and colors...\ Manage path labels).

Inclusion Enabling and setting of fixed downtimes in seconds

Tool changeON/OFF

• Definition of a fixed downtime for tool changes

Settings.

Display and colors...

Rapid traverse dashed line Alternatively, rapid traverse as a full line, as used for feedrate

Scale at edge of window Alternatively, as scale on the coordinate axes

Path labels Offers various possibilities under "Manage path labels" for displaying program labels, which have been inserted freely to identify specific points in the NC program (observe label syntax), as path labels at the corresponding point in the simulation graphics and then storing the associated graphic model in the buffer. Program labels can also be used to mark program sections, which can then be included by the central timing facility (see .. \ Downtime settings \ Timing mode \ In sections with labels). Path labels are specified in "Channel/spindle" as delimiter for section-by-section simulation in the same or different channels. You can save section models and use a search run to start again at that point without needing to repeat the preceding sections.

Use of color palettes

• Select a color with the cursor keys and press the Select key. The color of the focus frame changes.
• Use the cursor keys to select the object and press the Select key again. The object displays the selected color..

General colors In addition to the standard VGA colors, the color elements black and transparent to hide graphic elements are available in the color palette. Color selection option for background, blank, axis intersection, tool holder and tool edge.

6.8.5 Section-by-section simulation

Function

A procedure in which first the individual sections of a program are optimized one after the other without collision consideration is the preferred method for testing part programs graphically.

Section by section simulation allows the user to go to the individual section of the program via reference points (using block search).

The reference points are always defined by path markers (program labels).

6 "Program" operating area 01/2008 6.8 Program simulation

Prerequisite:

• In order to manage path markers (program labels, e.g. MARKER1), they must be programmed at the required position in the program.
• Using the "Manage path markers" setting (Settings -> Display/Colors -> Manage path markers) you can decide whether – the path markers are to be displayed in the graphic and/or – the associated intermediate model is to be saved.

Settings. Display and colors...

Intermediate stages of the simulation model can be stored next to the path markers, allowing synchronized resumption of simulation without resetting the graphic that already exists. You can skip any sections that are already optimized.

Block search: In the menu "Block search" you can select the path marker you wish to jump to.

Search run

Additional information

• You can also load the machining list in menu "Channel/spindle" directly from the current workpiece via the "Program selection" softkey or from a JOB list.

6.8.6 Quick display in the simulation for mold making

Target The function offers quick display of machining paths, e.g. like those used by CAD systems. Generally these part programs are very large.

Any existing work offsets, G0, G2, G3 are not taken into account, only those axis paths resulting from G1 are displayed.

Characteristics of quick display

• Simulation for mold making is a standard function
• Switching between 2D and 3D is supported
• Rotation of workpiece in 3D view
• Representation in the various different planes
• Size scaling, zoom for the displayed workpiece
• Search via row number/string
• Search via machining block which traverses marked positions
• Progress bar
• Execution of part program blocks
• Distance measurement
• Can be interrupted by other operating areas/can be aborted
• The programs to be simulated can be executed from external drives
• The NC interpreter does not take part in the simulation.

6 01/2008

6.8 "Program" operating area Program simulation

Activating Operation for mold making simulation is available in the Program operating area if display machine data 9480: MA_SIMULATION_MODE is set to a value between 0 and 2. -1 Standard simulation 0 Selection between standard simulation/mold making G1 blocks via operation 1 Mold making only, G1 blocks 2 Automatic mode selection via program size. The limit value for the program size is specified in the display Machine data 9481: MA_STAND_SIMULATION_LIMIT.

Size scaling The following scaling settings are available: Zoom in, Zoom out and Automatic fit window. The automatic scaling function "Fit to size" uses the part program to take the largest expansion of the workpiece in the individual axes into account.

Search In the submenu Details, the search function displays the part program block whose machining path traverses the position (which was previously marked using the cursor keys or softkeys) in the workpiece representation.

First activate Block search then use the cursor keys or softkeys to move the cross-hair to the desired location. Press the input key to search for the required block and display it. The cross-hair must be positioned in the area of the displayed workpiece section.

In the submenu Edit you can choose whether to search for a block designated by a block number or a block which contains a specified string.

The search function will return the blocks that match the criteria and display them in the 2-line program section above the graphic display and highlight them.

Progress bar The message line shows the percentage value of the entire part program which is displayed in the graphic. Loading the workpiece graphic can be cancelled at any time by pressing the End softkey. Changing to a different operating area interrupts loading the graphic. When you return to the Program operating area, the loading process is continued.

6 "Program" operating area

6.8 Program simulation

Rotation In 3D representation the displayed workpiece can be rotated around any of the axes. The rotation instructions become active after you press Accept to confirm.

Distance measurement In the graphic display you can use the Mark point A and Mark point B softkeys to enter two markers at the positions you have set via the cursor keys. The direct path (space diagonal) between the points is output in the message line.

6.8.7 Simulation with external network drive

Function

With the SINDNC software, you can link your control to external network drives or other computers and use this facility for program simulation. It is possible to access files on network drives from a part program using the EXTCALL command.

• With EXTCALL, the drives in the network are also searched for subprograms (SPF only) if the program is called without a path. Subdirectories are not searched. The program will also be found if the search range is defined with the variable $SC_EXT_PROG_PATH or if a path to a file in the network - even in a subdirectory - has been defined.
• Programs in the network drives (with the extension MPF and SPF) can be simulated.
• If write access is set for a network drive, file DPWP.INI is created and the current directory is treated like a workpiece.
• If write access has not been set, a DPWP.INI is created for each network drive in the TEMP directory of the HMI irrespective of the current directory. In this case, the simulation settings are lost when the directory on the drive is changed.

6.8.8 Simulation for orientable toolholder

Function

You can process part programs for orientable toolholders using the simulation function. The following boundary conditions must be observed:

• The simulation distinguishes whether a toolholder Y has been activated for a tool x.
• Changes in the active toolholder are not detected. This is why the simulation uses the toolholder kinematic set initially for a tool y.
• Changes made after first activation (TCARR=x) are not considered.
• To use several toolholder kinematics for one tool y, create several identical tools with different toolholder settings.
• Inactive files are grayed out.

6.9 Managing programs

Function

To allow you to handle data and programs flexibly, you can organize, store and display them according to different criteria.

The memory is divided into:

• NC memory (main memory and program memory) containing the active system and user programs as well as all part programs for immediate execution and
• Hard disk

Programs can be exchanged between the program memory and hard disk.

Part programs may be stored either in the program memory of the NC or on the hard disk, but they are always executed from the program memory.

The "Load" and "Unload" functions are used to load or unload programs to or from the program memory (see Chapter 9.3 NC).

Select a workpiece: A workpiece directory can be selected for machining in the currently active channel.

Use the cursor keys to select the workpiece

in the workpiece overview and then

press the "Selection" softkey.

• If only one main program (MPF) exists in this directory, it is automatically selected for execution. If the directory contains several main programs, the main program with the same name as the directory is automatically selected for execution (e.g. if you select workpiece SHAFT.WPD main program SHAFT.MPF is automatically selected). The program name is output along with workpiece information in the "Program name" window at the top right. You can start the part program you have selected by pressing the "NC Start" key.

• If an INI file of the same name exists (e.g., SHAFT.INI), it will be executed once at the first part program start after selection of the part program. Any additional INI files are executed in accordance with machine data 11280 $MN_WPD_INI_MODE.

When you select workpiece directory SHAFT.WPD you implicitly select program SHAFT.

If a .JOB file with the same name is stored in the workpiece directory, it is executed immediately.

See also Chapter "Job list" and "Sequence of operations" "Executing job list".

Find path for program call

If the call path is not explicitly specified in the part program when a subprogram (or an initialization file) is called, the called program is located according to the predefined search strategy.

Case 1: When a subprogram is called by name with specification of the data type ("identifier" or "extension"), e.g. SHAFT1.MPF the system searches through the directories in the following sequence:

6.9.5 Loading/unloading a program

Function

Programs can be stored in the NC memory ("Load") and then erased from it again ("Unload") after execution. This prevents the NC memory from being overloaded unnecessarily.

Sequence of operations

Position the cursor on the program to be loaded.

The highlighted program is loaded from the hard disk to the NC memory.

The selected program is deleted on the hard disk.

See also Chapter "Job list".

If enable is set "(X)", the program can be executed.

The highlighted program is unloaded from the NC memory to the hard disk.

The selected program is deleted in the NC memory.

Additional information

Programs which have been loaded to the NC memory are automatically marked with an "(X)" (in the "Loaded" column) in the program overview.

If the file is located both on the HMI and the NC, the identifier "X" is only removed when the files are no longer identical.

If the files have different time stamps or are of different lengths, the identifier is "!X!".

If you want to "load/unload" a workpiece directory and a job list with the name of the directory exists in the directory, then this job list is processed.

If no job list exists, all the files in that directory are loaded/unloaded (working memory of NC might overflow!).

6.9.6 Manage programs

Function

You can reorganize programs and files in the "program overview" using the "Manage programs" function:

• New... Select new workpiece/part program

6.9.7 Copying/inserting

Function

This section tells you how to copy files from a source directory to an existing destination directory.

Except when overwriting workpieces, the files are copied from the NC program memory or from the hard disk to: Hard disk (HD) or NC memory (NCK) or Buffer or Diskette (is specified as network drive) or Network drive (Network1 to Network4)

All directories with the exception of compile cycles can be copied to the destinations specified above.

Copy/insert

Several selected files or workpieces can be copied together in a single operation.

When copying workpieces: All associated files are copied too. All files with the workpiece name are automatically renamed to the new workpiece name. Files from the Workpieces directory can only be overwritten in another directory. All workpiece files of type .WPD can be copied from one drive to any other drive.

Specify the file name and file type

Copying from network drives: All data types known to the HMI are set according to their extension and the data management scheme. A dialog box is opened for files with an unknown extension. You can enter or change the name and file type - up to 3 characters are permissible.

If a file of the same name is already stored on the hard disk or in the NC memory, a dialog box prompts you to change the name and file type. If the source file and destination are identical, the existing file is not overwritten. The copy operation can either be canceled or an integer is added to the existing file name in ascending order.

6.9.9 Renaming

Function

As regards files, you can alter their name as well as the associated file type.

Sequence of operations

Manage program

The "Manage programs" softkey must be pressed.

Position the cursor on the file you want to rename.

Rename

The "Rename" dialog window opens.

Enter the new name.

When you rename a workpiece, you can also change the file type with the "Toggle key". File types are matched automatically in the part program and subprogram directories.

SELECT

There are two ways of renaming files:

• Renaming the workpiece directory
• Renaming a directory in the workpiece directory

Rename a workpiece directory:

When you rename a workpiece directory, all the workpiece files under that directory that have the same name as the directory are renamed. If a job list with the name of the directory exists, the instructions in that job list are also renamed.

Comment lines remain unchanged.

Examples:

Workpiece directory A.WPD is renamed B.WPD:

All files with the name A.XXX are renamed as B.XXX, i.e. the extension is retained.

If a job list called A.JOB exists, it is renamed as B.JOB.

If this job list contains instructions of file A.XXX and these are located in this workpiece directory, then that file is also renamed B.XXX.

6 01/2008 "Program" operating area 6.9 Managing programs 6

If job list A.JOB contains an instruction LOAD/Work.DIR/A.WPD/A.MPF it is renamed as LOAD/Work.DIR/B.WPD/B.MPF However, if a job list contains the instruction LOAD/MPF.DIR/A.MPF or LOAD/Work.DIR/X.WPD/A.MPF the files are not renamed.

Rename a directory in the workpiece directory: If you rename the files in the workpiece directory, all files with the same name but a different extension are renamed. Exception: If a job list of the same name exists in the directory, then this one is not renamed.

6.9.10 Enabling

Function

The program overview indicates whether a workpiece or part program is enabled. This means that: it may be executed (e.g., because it has already been tested) by the control after you select the "Program selection" softkey and the "NC Start" key. If you set up a new program, it is automatically enabled.

Sequence of operations

To set the enable for a program or abort it, position the cursor on the desired workpiece or part program in the program overview.

Press the "Change enable" softkey. A cross indicating "Enable issued" appears behind the workpiece or part program.

Function

If you are working on the hard disk, the following data are included in the log:

• Name of program currently being executed (execution from external source)
• Names of previously executed programs
• Prompts: e.g. "Do you really want to delete job?"
• Error list: Names of previously executed programs in which an error occurred.

Sequence of operations

Press the "Log" softkey. The "Job log for programs" window opens.

Depending on the status of the current program run, the following functions can be executed by means of the vertical softkeys (e.g. when prompt "Really delete?" is displayed in the "Query" window):

Function

With the SINDNC software, you can link your control to external network drives or other computers. The following conditions apply:

• The SINDNC software is installed.
• The computer or drive which you want to link up to is accessible/enabled.
• A connection to the computer/drive has been established.
• The softkeys to select the drive/computer connection have been configured by making entries in the file "MMC.INI".

See: Commissioning Manual HMI-Advanced (IM4)

Sequence of operations

You can access network drives 1 to 3 from level 0 of the Program operating area using horizontal softkeys 4 to 6. With the "ETC" key, you can access network drive 4 from level 2 using horizontal softkey 7. The cycle directories are also stored at level 2 and are assigned to softkeys 4 to 6.

When you press a softkey, e.g., "Drive F.:" or "R4711" the Explorer appears on the screen with the data of the external drive, e.g. "Drive F" or of computer "R4711".

You can perform the following operations (in addition to paging) via the vertical softkeys in the Program operating area:

• Copy/insert files (not directories) from network drives in the data manager. A type conversion cannot be performed according to the destination directory.
• Copy/insert from the data manager or a network drive to network drives. The files are set up on the network drive using DOS naming conventions. The file name used in the data management (source) is maintained.
• Deleting files (no directories) on the network drives
• Simulation
• Editing files (find/go to, mark block, edit) if write access to the drive is enabled.
• Files on the network drives can be simulated. This applies to files with the identifier MPF or SPF.
