PDM PDM systems enable companies to take

control of there Engineering Information ordata and manage overall engineering process.

PDM addresses issues such as control,

quality, reuse, security and availability of

engineering data.

Why to Manage Product Data?

Large volume of data

Data is on different media

Data is used by many people for different functions maybe at different sites

Data is used by many computer programs

Data exists in many different versions

Data has multiple relationships

Data may need to be maintained for many years

Product Structure

Break-down structure of a Product It provides Where-used information

Bill of Materials for the Product or Sub-assemblies in differentlevels

Car

Engine Assy. Gearbox Assy.

Cylinder Piston Assy. Speed Gear 1

Speed Gear 2

Counter Shaft


15/47

PEMP- AME2501


Product Structure Management

Product structure management facilitates the creation and

management of product configuration and Bill of Materials

(BOM)

Typically Product Structure (PS) contains attributes, instance

and location information of an assembly in addition to standard

BOM data

Standard BOM can be generated from Product Structure

automatically

Product Structure and parts can be associated with product

definition data like drawings, documents and process plans

Version Control

Version of a document is created.

Between saves (immediate instances of documents).

Independent of review process.

PDM keeps a copy of all versions till the document is

released (optional).

PEMP AME2501


24/47

PEMP- AME2501


Revision Control Deals with the modification of already released data / document.

Modification is not allowed on a released file. PDM vault maintains multiple revisions of same data.

To use the released data as the basis for new work PDM will copy

the file and places it in.

next revision code in the sequence. the initial status code in the status level of life cycle

Revise a document

After the document is released

Base-lined What is essential?

Revision sequence

Baseline

Baseline is a snapshot of the Data at a particular

instance of time

Baselines are created at important stages of the

product life cycle

PDM allows users to retrieve a particular product

configuration by baseline query

Work Management

Data undergo changes continuously

Work Management is what happens to data when

someone works on it A mechanism to capture all the changes to data

without affecting the original data

Ability to roll back the changes

PEMP AME2501


30/47

PEMP- AME2501


Check Out and Check InCheck out

For doing any modification on the PDM controlleddocument, user must check out the file from PDM

The user must have sufficient privilege to Check out the

document at the current state

When checked out, the particular document is locked for allother users for modification

Others can have read only access

Check In

Once the user completes the modification, the file can beChecked in back to EDM.

This action will release the lock for other users

Ownership of the checked in file changes from user to vault

Application Integration

How does the PDM system interact with data

authoring tools ?

Not all PDM systems integrate seamlessly withauthoring tools like CAD systems, Viewers, Editors

etc

Workflow Management Data flows around in the department depending on the

development technique and lifecycle

Work flow management is flow of data between people

Dependency between data is complex and change in one data

may have a far reaching effect on others

A triggering mechanism controls the progress of the work along

with a routing list Many people participate in chiseling a Part

Sequentially and concurrently How work flows between people involved

Sequential, Automatic, Conditional

Reviews (electronic voting) Who can do what

User access control Notification Warnings

Lifecycle Lifecycle represents different states the product goes

through from concept to becoming obsolete

Lifecycle will have many states

Each state in lifecycle will have a associated workflow.

Change in lifecycle state will usually involve a review

process

Change Control

Change control is the process through which

design changes are implemented.

Any change required for the released design data

will have to go through the change process.

Concurrent Engineering is a systematic approach tothe concurrent design of products and their related

processes, including manufacture and support

The objective of Concurrent Engineering, is to

command all the stages of the product developmentprocess simultaneously and to concentrate onshortening the development process and reducingdevelopment costs.

The idea is also to preserve the high quality of

production by constantly developing themanufacturing process

PEMP- AME2501

The idea of CE is very design and designer oriented. The

design, production, and marketing of products havetraditionally been carried out consecutively as a series ofrepeated functions.

The product goes through the different stages of designconsecutively;

the product designs are moved to production planning,which designs the production and the necessarymanufacturing software for the manufacturing process.

The procurement organization can then carry out materialacquisitions and production can begin on the actual product.

According to the principles of CE the whole process ought tobe carried out simultaneously in order to achieve the bestresult overall.

The idea is to make the totality efficient rather than torationalize individual sub processes
