Curso 3 de 9 en SpecializationDigital Manufacturing & Design Technology

There are opportunities throughout the design process of any product to make significant changes, and ultimately impact the future of manufacturing, by embracing the digital thread. In this course, you will dig into the transformation taking place in how products are designed and manufactured throughout the world. It is the second of two courses that focuses on the "digital thread" – the stream that starts at the creation of a product concept and continues to accumulate information and data throughout the product life cycle. Hear about the realities of implementing the digital thread, directly from someone responsible for making it happen at a company. Learn how the digital thread can fit into product development processes in an office, on a shop floor, and even across an enterprise. Be prepared to talk about the benefits, and limitations, of enacting it. Main concepts of this course will be delivered through lectures, readings, discussions and various videos. This is the third course in the Digital Manufacturing & Design Technology specialization that explores the many facets of manufacturing’s “Fourth Revolution,” aka Industry 4.0, and features a culminating project involving creation of a roadmap to achieve a self-established DMD-related professional goal.

The focus of module three is technologies used in the design process and

the insight they bring to the process.

We will examine certain tools, their specifics and their usefulness.

The first technology up for exploration is Computer-Aided Design or

CAD, a widely known digital tool.

After this lesson, you'll be able to state at least one limitation

of using paper drawings to communicate design intent and annotations.

And present an informed,

evidence-based case for implementing CAD and maximizing its use.

Why use computer tools in the first place?

Let's look at two business figures to think this question through.

The first figure is committed costs versus incurred costs.

This figure shows the relationship between committed costs and the project time span.

Even though the costs have not actually been expended, much of a project's costs

are typically committed early in the design and manufacturing process.

This second figure we'll look at is design freedom versus design knowledge.

This figure shows the relationship between knowledge and the project time span.

As the figure demonstrates at the beginning of the process

when we have the most design freedom we know the least

about the performance of the product in question.

What those two figures mean together is that

the period where we're typically spending or committing the most money

is also the period where we know the least about our product.

We want to shift the knowledge and design freedom curves by reducing the need to

align physical object to learn more about our product.

Digital tool enable us to do just that,

CAD helps us to do just that.

The CAD acronym can mean a few different things depending on who you ask, Computer

aided design, computer aided drafting or computer aided drawing just to name a few.

For purposes of this course we'll use the following working definition.

CAD is the use of computer capabilities to create and

edit geometric product models both 2D and 3D.

When an idea is formed it exist nowhere but in the mind.

That vision needs to be communicated to others in order to solicit input and

improve the design and ultimately to produce a product.

The communication can be a drawing or

a simple sketch, sometimes the proverbial sketch on the back of an envelope.

Imagine paper drawings.

Now, imagine digital drawings.

Compare these approaches as you contemplate storing drawings,

reworking drawings,

locating specific drawings, repeatedly using drawings for various purposes.

Some thoughts that come to mind when contemplating paper might be, lost,

damaged, degraded, and incomplete, among others.

With the evolution of computing technologies,

designers were no longer limited to pen and paper.

These sketches could be produced in a computer first in two dimensions,

then eventually in three dimensions.

Using specialized features, geometries can be generated defining the object

as either a cloud of points or the result of some set of equations.

In the resources section of this module, we have shared a link to a video that

features the transformative potential of CAD from an SME perspective.

If you're looking to learn more about commercially available CAD packages,

there are many offerings, including AutoCAD for 2-D applications.

For three-dimensional modeling, AutoDesk Inventor, SolidEdge, or SolidWorks

may be of interest as entry-level solutions for CAD, especially for SMEs.

For more capabilities PTC Creo,

Deso Catia and Siemens NX are frequently used higher end offerings.
