Designing a product is only part of the process. Now, can that product be manufactured? A CNC machinist works with computer numeric controlled (CNC) machines from generating the machine code to machine setup and run. Understanding both CAD and CAM is essential to this portion of a design. Even if you are not the end user who programs a machine, it is invaluable to know how it’s done. This knowledge translates directly to part design by helping make intelligent design decisions with manufacturing in mind. This course introduces you to the integrated CAD/CAM approach behind Fusion 360 CAD/CAM as well as 3D printed design setup and finally assembly and testing. All stages of product design in one place! After completing this course, you will be able to: • Explain the Fusion 360 integrated CAD/CAM manufacturing workflow. • Summarize the trends that are influencing the future of manufacturing. • Demonstrate knowledge and skills in foundational concepts of Fusion 360 CAD/CAM software. • Set up a Flight Controller. • Assemble a quadcopter. • Fly the final design.

Quadcopter Assembly

You finally have a complete design and all the parts in hand, now what? This stage of the process can be a rather large task the first time through. From complex wiring, cable management, and overall assembly, we will step through the process. Even if you aren’t designing and building your own quadcopter, this is great information to have for when you do.

In this lesson, we'll be talking about Airframes.

After completing this lesson,

you'll be able to visualize

airframe options and understand function-based airframe design.

Throughout our course, we've been designing our own airframe,

but there are plenty of them that are available off the shelf.

The airframe is important because it holds all the components together,

such as the motors,

the flight controllers, as well as the batteries.

But why would you want to design your own airframe

if there's one already available off the shelf?

This specific one is a super light series and

allows you to create essentially a racing drone.

It weighs about 125-130 grams,

so it's a little bit lighter than ours,

but it lacks a few key things.

We don't have any protection for the motors or props,

and we don't really have

any surrounding geometry to help protect all the other components.

Now there are some pleats here that can allow you to keep the flight controller safe.

But in general, it's a fairly open design because it's meant to be as light as possible.

Earlier on in our course,

we used a smaller modular type 3D printed arm.

Now this one was printed on a micro 3D printer,

which has about a five-by-five inch build volume.

You can get a small desktop 3D printer like this and

create your own designs without having to print a rather large design.

The one that we designed for the course however,

had a very specific design intent.

We wanted to make sure that the motors were upside down and that we

protected the props as well as the motors and all the components.

We have this large airframe to allow us some flexibility when

we land or also if we bump into anything, walls or ceilings.

We made sure that the entire top of the design was nice and smooth,

so that we didn't hit the obstructions if we were flying inside of buildings.

Now that's a big difference between a lot of the off the shelf components

because our motors are upside down and the props are facing down.

That means that we can fly directly up to a ceiling without

fear of crashing or damaging any components.

So when you consider designing

your own airframe as opposed to buying an off the shelf one,

you need to consider what's available and what

type of functionality you want to add that it's not currently available.
