An all-digital machinery development process accelerates new

product introduction, promotes development team collaboration

and fosters an environment of continuous innovation that keeps

you a step ahead of competition.


Increasingly complex

business challenges

Industrial machinery is so critical

to a company’s success that it has

been called “the lifeblood of the

production process.” Because

companies can’t thrive without

fast, reliable, state-of-the-art

machines to manufacture their

product innovations, they place

extreme demands on their

machinery suppliers and in-house

machinery developers.

If you’re in the business of

producing industrial machinery,

you know about these extreme

demands: nearly impossible

delivery schedules, increasing

quality requirements and lower

price expectations, to name a few.

As you work to meet these

demands, you face your own

challenges as well.

In many cases, you’re facing

new competition, forcing you

to reduce prices and deliver

more value. By now you probably

have a supply chain that’s spread

throughout the world, which

helps reduce costs but brings its

own challenges.You may also have

your own global design and

manufacturing facilities you need

to integrate. And as you strive to

meet these challenges, you must

still be able to respond quickly to

new conditions in local markets

with timely and winning proposals

and quotes.

Digital product development

meets the challenge

Digital product development can

help you meet and excel at all

of these challenges. An all-digital

machinery development process

enables you to accelerate the

introduction of new products

while still promoting innovation

and maintaining the flexibility

and speed to react to changing

requirements.Working digitally

within a managed product

development environment, your

entire development team can

collaborate from a continuously

up-to-date digital product model.

This eliminates a high percentage

of development costs that are

currently wasted, and removes

activities that don’t add value.

And, most importantly, digital

product development helps you

foster an environment of

continuous innovation – an

environment that consistently

results in products and services

that clearly differentiate you

from your competitors.

Siemens PLM Software

production-proven applications

and process automation tools

give machinery developers

everything they need to manage,

automate and optimize product

development. In the following

pages, we’ll show you how digital

product development based

on Siemens’ applications can

transform each step in the

machinery development process.


Knowing where, when and how to compete

Digital product development is not just a process that begins

with the CAD modeling of a new machine. Digital product

development encompasses the entire range of development

activities, including business planning. By providing a single

source of product information in a format that makes sense for

each individual user, digital product development optimizes

decision making.

For example, the Executive Dashboard, powered by Teamcenter ®

Community software, provides senior management with real-time

visibility into the business information they need.With an instant

snapshot of current operations, managers can see whether critical

workflows have been executed as planned, whether deliverables

have been met and where the bottlenecks are.They can use these

same tools to measure the success of completed programs.

Did the programs meet cost and delivery schedules? Did they

satisfy requirements for performance, safety, reliability and other

compliance metrics?

Digital product development brings the ability to implement

requirements-driven design, where product requirements flow

through the product development process and directly influence all

product development decisions. In many cases, requirements-driven

design begins with a request for proposal or quote. Let’s look at

how this is handled in a digital product development environment.

Faster responses to customer requests

When a bid request comes in, it is entered into Teamcenter

and forwarded to the appropriate executive.The new request is

color-coded for immediate attention. Most bids contain multiple

documents such as functional specifications for the new machine,

general terms and conditions of the project and sometimes other

information such as a CAD file showing site layout.

Using the Executive Dashboard to review current and historical

data, the executive makes the decision whether or not to

follow up on this RFQ.Then the executive assigns a routing

slip (a standard template) to the relevant manager, asking the

manager to perform a feasibility study and prepare a response

for the RFQ.

Once managers log in to their own workspace, they can view the

feasibility analysis as a new task. In the managed development

environment, the necessary information to support this request

has been automatically routed to the manager, eliminating time that

would otherwise have been wasted searching for it or waiting for

someone to collect and send it.This is a major factor supporting

lean design initiatives. As a result of these streamlined workflows

and captured knowledge for best practices, the feasibility study

is completed very quickly.The project is ready to move on to the

next step, concept engineering.

P R O V E N R E S U LT S

“We have a lot of competition, so we always have

to be one step ahead in terms of product development.

Our knowledge of customers' needs, combined with

the managed development environment we have with

Teamcenter and NX, helps us do that.”

SylvainTalbot

Designer and Teamcenter Implementation Leader

Concept engineering in the managed development environment

The managed development environment keeps the project moving

along and on schedule by ensuring that all necessary information

automatically travels to the next participant in the process,

at this point typically a product engineer. As individual engineers

review this information, they can search the product information

database, where they might find that a similar machine has been

built in the past. Up to this point, it’s possible that the engineer

hasn’t even worked in the CAD system. And if the job is simply

a matter of configuring the machine to order, with no required

engineering work, it would be unnecessary to enter the CAD

system at all, thanks to Teamcenter’s digital mockup capabilities.

If the customer’s request requires some conceptual design work,

NX ® software allows the designer to get started quickly with a

platform engineering approach. Platform engineering works with a

template containing only the components and geometry that will

become common to all variations of a machine. It provides an easily

configured starting point that is enough for preliminary design

investigations. Later, this template will also be used to drive the

detailed assembly design.

The platform engineering capability of NX differs from most

CAD systems, which encourage designers to dive into details

at an early stage, linking geometry, adding constraints and driving

multiple dimensions and variables with little regard for downstream

application of the model.With this uncontrolled approach,

product-level issues only become apparent relatively late in the

process when the digital mockup is well populated and changes

become difficult and costly.

Fast feasibility studies

With NX, proposed machine layouts are captured in the Visual

Editor, which allows the engineer to input different dimensional

information and perform “what if” analyses. Once the driving

parameters are entered, the engineer can propagate changes to the

entire assembly in a controlled manner. For even greater control,

NX can provide visual feedback of the before and after states,

so designers can easily determine the impact of any changes.

It could be that certain modules meeting the specifications

and requirements for the new machine already exist in the

database. It is easy for the engineer to find and attach them to

the preliminary machine configuration because Teamcenter allows

components and modules to be saved and searched based on

functional requirements and purpose. Also, if the customer’s request

includes specifications created in a different product development

system, such as an AutoCAD drawing of the proposed machine’s

location in a factory, Siemens’open systems philosophy allows access

to this data, regardless of its source, without the need for costly and

risky data translation.

With the feasibility stages complete, the engineer signs off and

approves the next step in the development of this new machine.

It is now time to begin the detailed design.

P R O V E N R E S U LT S

Sauer-Danfoss, Inc. leverages the NX open application

programming interface – called NX Open – to develop

custom applications using many of today's most popular

programming languages.The result is an environment that

enables virtual product optimization.

Detailing the design

After getting off to a rapid start with platform engineering and

having confidence that the product direction is feasible, the next

step is detail design. At Siemens, we recognize that in many

companies product design fuels the entire development effort and,

with this in mind, we continue to invest heavily in the ergonomics

of our software to deliver the most intuitive user interface that

can be used out-of-the-box. But we also make sure that NX

has the flexibility to be tailored to the individual preferences

of each designer.

The NX user interaction model uses dynamic techniques for

feature creation and editing, so designers can concentrate on

creating the geometry they need without being forced to interact

with obtrusive windows and dialogs.Through this approach, NX

offers productivity through ease of use that is typically associated

with less sophisticated systems, while removing the traditional

barriers to learning the kinds of advanced functionality that

NX delivers.

A significant advantage of digital product development is the

ability to establish a managed parts library.This helps ensure

that any component used in a design meets

company and program requirements.

Once components have been

classified in a part

dictionary,

they can be identified and located quickly.This not only eliminates

redundant component design efforts but also accelerates design

cycle time and sourcing lead time by re-using preferred parts and

existing supplier relationships. Inventory costs can also be reduced

by minimizing part proliferation, lowering inventory levels and

eliminating excess and obsolete inventory.

Creating virtual assemblies

NX offers proven assembly management tools that make

working with the large and complex assemblies typical of

machinery development easy and efficient. For example, a number

of innovative selection and display options make it possible to

eliminate clutter and quickly isolate focused design areas.

With virtual assemblies, machine designers can optimize not just the

fit, but also the function of moving components. NX offers a fully

scalable solution ranging from simple motion studies with

clash and clearance detection to full analysis of mechanisms with

joint considerations, linked to structural analysis for loading

studies. Because these simulation tools are fully integrated with

NX, this motion analysis can be done as part of the design effort,

rather than waiting until the design has developed to the point that

engineering changes are costly in terms of both time and money.

Another important part of digital product development is the use

of NX DesignLogic, which lets engineers embed design knowledge

and engineering rules into NX models, rather like having a builtin

engineering handbook to monitor, check, advise and

validate critical engineering features and components in

each design. And, unlike most capabilities with this level of

sophistication, they can do this on the fly, without resorting

to custom programming. Once created, these knowledgeenabled

design features can then be made available to the

entire development team. DesignLogic allows companies to

capture lessons learned for potential re-use, promoting the use

of best practices without placing additional burdens on

the designers.

Simulating and validating the design

With digital product development, it is possible to simulate and

validate products early in the design process, while the machine

still exists only in software. NX Simulation Process Studio helps

companies reduce their reliance on expert analysts for common

design simulation tasks. Once analysts have created templates in

Simulation Process Studio, the templates can be easily used by less

experienced users.Templates are instantly loaded and automatically

executed as stored processes. Designers follow the prompts of a

wizard-like tool to run the preferred simulation process.

Moving simulation activities into the upfront design process allows

more concepts to be reviewed, reduces direct costs associated

with expensive physical prototypes and enables faster, more

informed decisions.The result is better performing products

and higher margins.

When drawings are necessary, NX facilitates the process

through the use of drag-and-drop drawing templates, simplified view

creation, interactive previews and multiple options for displaying

the model. NX drafting tools support all major national and

international standards for engineering drawings.

Once the views are in place, the designer can extract the product

manufacturing information with a single command.This not only

reduces the amount of annotation work required but greatly

reduces the potential for errors by improving communication

from engineering and design through manufacturing and inspection.

Documenting the design

With digital product development, the task of creating drawings

takes advantage of all the product information that has been

captured in previous stages. For example, while a machine is

being designed, NX continually promotes the re-use of any

information necessary for manufacturing and downstream

applications. It does this through the use of advanced tools

for creating “smart models” that include annotation and

product characteristics such as material and surface

finish embedded into the design data. In fact, Siemens

leads the development of standards for 3D

model annotation.

This product manufacturing information (PMI) streamlines

and simplifies the production of engineering drawings and

can also promote the use of drawingless design processes.

“The implementation of NX, Teamcenter and Tecnomatix

has resulted in a variety of benefits, including the realization

increased security and the reduction of hassles and errors

related to data transfer.”

Options and variants

To leverage long “service life” from a new machine, many companies

create options, derivatives and variants from an existing platform.

This is a good way to create a cost-effective mix of products and

maximize revenue potential. Digital product development in NX

supports this practice, providing all the functionality needed to

quickly develop a series of related products from the same platform.

Throughout digital product development, system-level parameters

and intelligent interfaces are established between the various

systems making up a new machine design.Changes in product

configuration are simply and easily managed, and interacting parts

continue to fit and function together properly.

Once created, any new options and variants can be saved with

a new name and description, making the new platform available

for other development teams in the future. As the platform and

module database grows in size and intelligence, it becomes even

easier for development teams to find and re-use product, process

and manufacturing information.

“In addition to helping compete in the international

CNC machine market, NX has helped open the door

for ANCA to make a move into other areas such as

medical equipment.”

Sourcing

The benefits of digital product development extend beyond the

company to its interactions with its supply chain.The key to

effective communication with suppliers is overcoming the

differences in development systems and surmounting problems with

data exchange.Truly effective communication includes all necessary

product information, not just drawings and model geometry.This

can include specifications, proposals, images and other documents.

XpresReview from Siemens PLM Software supports this critical step

in digital product development. XpresReview solves the problem of

how to share multiple documents in a collaborative environment

using the concept of packaged collaboration files. Designers create

“packages” for suppliers containing items such as: lightweight

representations of drawings and models, including all product

manufacturing information; spreadsheets containing specifications;

pdf files, image files and so on.

Sending a package file from XpresReview is similar to creating a

meeting request in Microsoft Outlook. An email is automatically

generated, and the package file is automatically attached to that

email.The recipient can then use the viewing, measuring and

sectioning tools in XpresReview to interrogate the contents of

the file, add some markup and comments along with additional

files if necessary and return the whole package.

The ease and openness of XpresReview allows extended

participants (such as sales and marketing organizations, partners,

suppliers and customers) to take part in the concept design

process early and often without incurring the cost or complexity

of lengthy review cycles.

Manufacturing in digital product development

Machining applications are fully integrated in digital product

development, leveraging existing design data for accurate and timely

creation of production tooling and machining toolpaths.There is no

need to translate, transfer or duplicate data and effort, which means

there is less likelihood of introducing errors.

NX machining applications incorporate highly automated toolpath

programming techniques that can reduce programming time by up

to 90 percent compared to traditional methods. NX also provides

fully integrated tools for simulation and validation of the entire

machining process.The solution is scalable from toolpath display,

through dynamic material removal, to full machine simulation.

Just as with design components,Teamcenter allows manufacturing

organizations to organize and classify tools, fixtures, processes and

other manufacturing information so they can be easily accessed and

re-used on multiple different projects. In addition, the combination

of NX with Teamcenter manufacturing applications offers a highly

effective capability for part process planning.The Part Planner

application allows the manufacturing engineer to create a process

plan defining all steps in the manufacturing process, and to associate

and assign resources and to create a variety of reports.This

solution helps provide overall process direction and management,

reduce errors, improve repeatability and increase the effective reuse

of proven methods.

Digital product development brings important benefits to bear

on the manufacturing process. In addition to leveraging design

data and eliminating data translation and duplication, digital product

development makes it possible for companies to understand the

impact of design changes on manufacturing resources and to

optimize manufacturing resources.

Transforming product development

Digital product development transforms every step of industrial

machinery development by providing a unified solution that covers

the entire process, from responding to a proposal, through design

and manufacturing of the machine, to leveraging the platform for

other uses. Digital product development is built on five key

elements of NX:

Unified product development solution. Seamless integration

of NX applications rapidly propagates changes of product and

process information, replacing point solutions with a unified

development system, from concept to manufacturing, ensuring

that design changes are accurately reflected in every

downstream process.

The managed development environment. NX solutions

include fully integrated, synchronized management of all product

data and process knowledge to transform product development

with a structured collaborative environment.This enables companies

to increase the re-use of product data and supports

lean processes by eliminating duplicate effort.

Knowledge-driven automation. With NX, companies can

apply product and process knowledge across all elements of

product development to automate processes and maximize

re-use, streamlining the product development process.

Simulation, validation and optimization. Comprehensive

simulation and validation tools in NX automatically check

performance and manufacturability at every step of the

development process for closed-loop, continuous,

repeatable validation.

System-level engineering. NX-structured conceptual models

standardize design practices and allow rapid creation of variants,

transforming development from component-based design to a

systems engineering approach.

Siemens in the machinery market

Siemens PLM Software has been transforming product development

processes for machinery companies worldwide for more than

5 years.We have more than 18,000 customers who design and

manufacture industrial machinery and more than 15,000 engineering

users working in this industry.

There are significant installations of Siemens software in every

category of the machinery market, including custom/special

equipment, commercial equipment, heavy industry and so on.

Companies in these industries rely on digital product

development to help them compete.

“We have a lot of competition so we always have to be one

step ahead in terms of product development,” says Sylvain Talbot,

lead designer at Rotobec, a manufacturer of continuous rotation

forestry attachments (grapples) based in Quebec.“Our knowledge

Business challenges resolved

With digital product development, industrial machinery

manufacturers have a comprehensive solution to the business

challenges they face.

Globalization and global development. Managed development

environments allow fast access to widely divergent types of product

and process knowledge generated by otherwise incompatible

applications and ensure up-to-date information flows on time to

users in all areas of a business.

The bidding/RFx process. Knowledge-rich templates automate

the bidding process for faster and more accurate response.These

templates manage the entire development process and improve

understanding of resources, costs and profitability.The modular

approach drives fast and accurate configuration of alternatives.

Modularization, standardization and re-use. A systemsbased

approach structures complex assembly design projects into

functionally self-contained modules that can plug and play. Managed

development environments make it easy for developers to find

and re-use product, process, manufacturing and service information

and re-use assets across multiple take-to-market programs.

Optimized or “lean” development. A unified development

solution streamlines processes from concept to manufacturing

and serviceability. It also helps companies avoid delays and errors

that result from data re-creation; by removing collaboration

barriers, it facilitates more effective data sharing.With a unified

development solution, it is possible to re-use designs across

product platforms and automatically communicate changes to

downstream processes.

Product quality and conformance. Requirements-driven

design transforms product requirements into quantifiable

constraints that are monitored and validated throughout the

entire development process.

Aftermarket business opportunities. Platform engineering

and modularization allows rapid delivery of product enhancements,

derivatives, niche offerings and add-ons. Managed development

environments provide on-demand information for teams that

maintain, repair and overhaul machines in service.

Supplier integration. An open systems philosophy enables

better communication and collaboration in the supply chain and

unites disjointed partners around product information. It enables

early supply chain participation in the product development process.

Cost of ownership for new technologies. Scalable solutions

permit a company to begin by addressing a specific issue or area

of the product lifecycle and build upon that foundation. Open

systems maximize the value of current information and technology

investments. Prepackaged solutions consolidate and integrate

disparate systems and limit implementation costs and risks.
