Create the Simulation

Overview In creating a simulation of an assembly process, the manufacturing enterprise gains valuable information regarding the optimization of the process. Best trajectories to avoid clash conditions and part assembly sequencing are among the first, most critical information to be obtained. Now that the structure is set and the data ready, the movements of the simulation can be added. For the examples shown here, entire subassemblies are moved and conflicts will necessarily occur.

Objectives Topics in this module are:

Create move activities Use Dynamic clash to identify conflict conditions Edit and Delete move activities Add advanced part motion Run, Compile and Replay the simulation

Create Basic Moves

About Move Activities Creating movement is the basis of the simulation. Movements generate the shots and tracks that the simulation will replay for analysis and visualization.

Because it is a virtual world, a basic move can be constructed without reference to other elements in the world. This can be refined with other tools.

Moves can only be created with reference to a process activity. They can be inserted before, after, or as a child of the process activity. This restriction guarantees that the process plan accurately reflects the intended movements of the parts for the assembly or disassembly sequence. This creates a valuable asset in Design for Assembly discussions. It also forms the preliminary information for the generation of work instructions for the shop floor production effort.

Add Dynamic Clash Detection

About Dynamic Clash RECALL: A basic move activity can be created without consideration of other elements in the world. Dynamic Clash is a function that will identify clash conditions as a move is being performed. Critical information regarding the direction, axis orientation, and path that the part must travel to locate properly without conflicting with any of the surrounding geometry is obtained .

Activating Dynamic Clash when creating movements will assist in determining the viability of the intended movement by providing feedback when a clash condition is present. This information allows modification of the move before it is recorded and becomes part of the simulation. Using this functionality when creating moves in a simulation greatly reduces the need for editing later. Dynamic Clash can also provide early indicators of deficiencies in the process plan by demonstrating unsolvable clash conditions, thereby allowing modification of the process at an early stage of effort. While Dynamic Clash offers a great deal of visual input, it does not analyze or generate reports. This functionality will be addressed later in this course. © DELMIA Corp. 2005

Edit and Delete Moves

About Editing and Deleting Move Activities The ability to modify movements greatly enhances the speed and utility of doing simulation studies. It is not uncharacteristic for a completed simulation study to be modified and reused in a slightly different context in order to have multiple scenarios to compare and evaluate. It is also not uncharacteristic for a simulation under construction to require modification based on information that becomes apparent with the use of Dynamic Clash or other downstream analyses. Whether using Hub or file based systems, this iterative interaction with the process plan is crucial to the development of a viable study. EXAMPLE: Dynamic Clash may reveal that the process activity calls for the movement of a sub-assembly which cannot be accomplished with the sub-assembly intact. In this case, the process plan requires modification to include process activities at the component level. Once accomplished, move activities can then be generated for individual parts, or part groups, in a sequence that will prevent clashing.

Moves can be modified or deleted at any point during or after construction of the simulation.

Add Advanced Part Motion

Create the Simulation

About Adding Advanced Part Motion Precision and efficiency are gained by using advanced part motion when creating move activities. Advanced part motion comes from sophisticated manipulation of the Compass. In an assembly study, if a part must end up in an absolute location, the move activity can be pre-set to that location. This eliminates the need for multiple move activities. If it is desirable for movements to be a some standard incremental unit of rotation (like 90 degrees) or translation (like 2 meters), then it is far more efficient to preset moves to meet these requirements. In some cases it is necessary to manipulate the part with respect to a local axis like a robot or human. In this case the part’s origin is not always useful and a change of placement of the compass is called for. Smart Target is a functionality that will permit the user to snap a move activity to an axis, a line or a plane. It gains efficiency by snapping into alignment rather than forcing the user to try to find it.

Add Advanced Part motion

About - Refine moves with Compass Manipulation Editor Basic moves are created by grabbing the geometry and moving it to a location that appears to be visually acceptable. This is called relative placement. If the geometry must move to a known location, it is far more efficient to define that location and eliminate the need for visual guesswork. Efficiency is also gained in the reduction of moves thereby influencing cycle time. Likewise, if parts must rotate or move along an axis in specific increments as in automated assembly, compass parameters can be set to reflect such situations. Compass manipulation refinements can be made at the shot level of a move activity and are available as part of shot modification with editing and deleting move activities.

About - Refine moves with Compass Manipulation Editor The top part of the box indicates the current location (relative to the world origin) of the part involved in the move activity.

The bottom part of the box permits the designation of the linear distance and/or the rotational angle for each compass move.

© DELMIA Corp. 2005

Revising these settings to a known set of coordinates will cause the part to move to the identified location and angle. Click Apply once changes are made.

Defining the position and angle of the move does not consider clash conditions.

If multiple moves are required, the absolute position can be set as the first or last shot of a move activity.

In this example any move activity that is initiated will only be able to move in 500 mm increments and any rotations will occur only every 45 degrees. The constraint was applied to every direction. R15AP2

When creating basic move activities, the part is manipulated with the part’s origin relative to the world origin. If there is another influence in the manipulation of the part, like a human hand, or automated pick and place, it will be more effective to see the move from the vantage point of the physical contact. Moving the compass to the location where the part will be handled will allow the simulation to represent more realistic visualization of the process, even without the resources being present.

About – Using Smart Target Smart target is a functionality that will allow the user to snap a move activity to a plane, line or axis. It is useful for aligning a move with a location rather than estimating it visually. This reduces the recording and editing of unnecessary move activities, again influencing cycle time. As part of the Manipulation toolbar, once activated, the Smart Target function has a selection of ways to align a part location to the target location. The selection can be chosen to constrain the type of targeting or it can left at the default “any geometry.” The cursor will display the type of selection that will be made as it identifies legitimate selections for targeting.

The part can be inverted by symmetry which creates a mirror image but changes the data

The Dynamic Smart Target function will not display a dialog box because it permits free selection of a series of constraints to align. These constraints must be selected between the part to be moved and the final location of the part. All of the same features can be selected; lines, planes, axis, points, etc. Once selected, moving the part to proximity of the target will cause the part to snap into place. © DELMIA Corp. 2005

Run, Compile and Replay

About Running, Compiling and Replaying Simulations Once move activities for a simulation have been created, the simulation can be run. Each move activity is viewable separately. However, the run simulation command will go through the process in the sequence called for by the process activities. Compiling a simulation is the means to save a simulation in its current state. This is useful if variations on a baseline process are part of the study as this will save time in recreation. Compiling each variation of the process will capture that variation’s advantages and disadvantages and offer a potent tool for discussion and evaluation. It is sometimes necessary to compile the simulation in order to conduct analyses. Replay is a means of viewing a compiled simulation. The replay of a simulation can be captured as an AVI to facilitate communication.

Create the Simulation

Run, Compile, and Replay

Replay the Simulation - Procedure A compiled simulation is viewable through replay.

1

From the Simulation toolbar, select the Replay icon.

The Replay toolbar appears. It works like the other player toolbars.

The Replay options will allow you to change replays and the speed selection will allow you control the speed of the replay.

2 Play the simulation in the desired mode. A replay is a captured state of a compiled simulation. Changes made to the process after the replay was created will not be included. It is not unusual to have multiple replays of the process in various stages of development or in the context of various scenarios. © DELMIA Corp. 2005
