Hello there,

Tory at MyDIYCNC here. Today I want to show you how to use a very useful piece of software from Autodesk called: Fusion 360. With this software you can create simple 3D Models, to elaborate and complex 3D models.

What I hope to teach you today is how to create a simple model on Fusion 360, and then create a tool path in which you can then run the G Code on your MyDIYCNC machine or another CNC machine.

Let's get started!

Step 1: Open Up Fusion 360, and Begin Creating

First of all, go ahead and install Fusion 360. After you have installed the software, open it up and move to the next step.

Step 2: Create Your Simple Model

Follow the directions for this step.

1. Select the drop down menu CREATE, we are going to use just a simple cylinder model.

2. Select the face of the model, the X and the Y axis are the RED and GREEN lines, and the Z axis is the BLUE.

3. Specify the diameter of your model, we are going to make it 3 inches.

4. Specify the height of your model, we are going to make in .5 inches.

5. With your model base created you can then modify it with a number of tools, we are just going to use the Fillet tool

to demonstrate, and give the model a little smooth curve to it.

Step 3: Save Your Model and Begin Creating a Tool Path

In this step we will now create our tool paths. Follow each direction closely.

1. Save your current Simple model to keep it on file.

2. Select from the drop down menu CAM, now you will enter into the Cam section of the program.

3. Select from the drop down menu SETUP,this will start a new setup for your tool paths.

4. First you will set your Stock Point, set it at the top bottom corner of the model.

5. Under the STOCK options you will define the size of your stock, L x W x H.

6. You also want to offset the model to the bottom of the stock instead of center of the stock.

Step 4: Creating a Tool Path CONTINUED

Continue creating your tool paths. Follow the directions.

1. Select from the drop down menu 3D Pocket Clearing, other options can be used but we will use this to demonstrate.

2. First in the tool path setup you want to select a tool, we must create a new end mill now.

3. Now you will enter in the specs of your new end mill, size, diameter, shaft, flutes, so on and so forth.....

4. After you have created your new end mill, you can move over to retract and safety heights. Just make sure and inspect that the heights do not conflict with the model.

Step 5: Creating a Tool Path CONTINUED

Continue to follow directions.

1. Now you will edit your passes.

2. Be sure to set machine shallow areas, as this will give a better quality cut.

3. Set your manual Step over to the correct specs according to your end mill size.

4. Set Direction the Conventional.

5. Press OK once all Specs are set. Now Fusion 360 will generate your tool paths.

Step 6: Post Process

Now with your tool paths generated you will take the last step which is the Post Processor.

1. Select from the drop down menu POST PROCESS

2. In the Post Process menu, you will select the MYDIYCNC Post, or what ever other post you are using.

3. Save the Post and VIOLA! You are done!

Step 7: Good Job, Well Done!

Nice Job!

You have successfully created a model in Fusion 360, created tool paths, and completed it with the post processor!

You can now use your G Code file that you have created, as you can see it is successfully loaded into FabCam. Creating a model and learning how to create tool paths can be easy, with some patience and imagination you can make anything! Be sure to look at my other tutorials here on instructables, and check out our site at MyDIYCNC.com

Thanks for participating guys! Enjoy the CNC world!

Very helpful! Thanks for sharing this information.

Hi! Thanks for sharing this ible. Is there a way to specify drilling a holes of the model separately from milling; let's say for step one - drilling, for step two - milling?

superviser (author)2016-01-06

nice work dude your instructions need a update you have one step missing, what is a best practise, start with a component and name then activate it, once you have finished the sketch name it as well, then the body after it.

buy the way you always get jumper in people who don't know what they are talking about fusion is free for hobby and start ups or $300 US a year

stumitch (author)2015-12-15

Correct me if I am wrong but Fusion 360 for Mac is free, yes? Are the steps you outline compatible with the free version? My thought is to generate the code than use Universal G-Code sender to use my Arduino shield to run my machine.

DavidS40 (author)2015-03-26

Fusion, pricey... If you come out with one on something free, I bet you'd get more attention from the not so rich club (lot of folks on instructables would appreciate it).

I could be wrong, but I think Sketchup 'make' can do this.

LOL Sir...... you again..... I think the instructable is just how I want it, If you want to do it then feel free to make one yourself :D

If you do your research as well, Fusion 360 is actually free to a lot of people.

DavidS40 (author)Tory MYDIYCNC2015-05-05

Yep, I'm a great fan of the 'free tools and information' club.

Here's a great one for folks... best I've found yet.

Try not to take my comments as anything but helpful to others, as add-ons to yours. This being a public forum, is the concept... so don't feel personally bad when someone adds a suggestion. Posting an instructable invites the public to comment and improve... a very positive thing.

Hi again,

I feel its 100% true,

Thanks for your great information.

Tory MYDIYCNC (author)DavidS402015-05-11

LOL

Syed imran (author)DavidS402015-09-14

Hi there,

Yes i agree with you.

Thanks.
