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.

Waterjet Program

Most retail production quad and multirotor chassis are made of flat plates of carbon fiber or injection molded plastic. Flat plates of composite materials are often cut on a machine that uses high pressure water and abrasives. This allows you to cut almost any material without introducing heat, which could affect its structure and properties. In this week's lessons, we'll explore how to setup and validate a 2D waterjet cut on a quadcopter chassis.

In this lesson, we'll be updating a parametric design.

After completing this lesson, you'll be able to update a parametric feature,

create a toolpath, and simulate a toolpath.

Now that we have our two profiles created,

let's go back to the model workspace and let's make some adjustments to the shape.

I want to start by editing the original sketch.

Now I'm going to adjust this 50 millimeter dimension to be 60.

That'll make the side bolsters a little wider,

and it's going to adjust some of the cut-outs.

We also have some various other options that we can change,

but let's go ahead and navigate back to the CAM workspace.

And notice that we have to regenerate these toolpaths.

If we take a look at where the original toolpaths were,

you can see how the size of the body has changed.

I'm going to press, Control,

G on the keyboard to generate the toolpaths again.

And once they're done,

we can take a look and make sure that they've updated to the new shape.

So, now let's create another 2D cutting operation.

I want to talk a little bit about the selection process.

Initially, we selected all the internal contours.

If we select the top face,

we'll automatically grab the internal and external contours.

If you left-click on one of them,

it'll bring up the selection options.

Now these change based on your original selection.

You can see here, that we can change whether or not we want internal and external,

internal or external only.

We can also trash it, remove, or add.

If you select an edge and you select it again,

you have the available option to select or add loops,

as well as open contours.

If we select open,

and we select an additional edge,

we hit the plus sign,

we now are creating a toolpath just for this path of edges.

Now in these cases,

you'll have to make sure that you use an adequate lead-in and lead-out radius,

as well as sweep, so we can see what the toolpath looks like.

With those values, you can see that the tool does a nice arc in,

it cuts that section and arcs out.

If we simulate this,

we're looking at just cutting that one section of our geometry.

So in some instances,

you might want to simply select a face to grab all internal and external contours,

or just the internal or external ones individually,

or manually select them,

by changing the selection options by holding down the left mouse button.
