Thank you. Maybe you should consider buying a lathe 😁

I actually decided to convert my mini lathe to CNC so this video comes in useful@@MechanicalAdvantage

Excellent. That’s what I like to hear.

Hi Brett. I decided to add something around turning. It would be nice if there were a bigger percentage of lathe to mill people but I think the ratio is pretty skewed. I'll see what ideas I can up with in the future.

I run into this a lot. CAM software can do a lot of things that wouldn’t be done when writing code by hand, such as the lead ins and lead outs as an example. Have you tried running a part from Fusion? Did the program do what it was supposed to? You can also contact a post editor that can format the output of the code to be more what the operators expect. I know this last part seems crude, but often I tell them to hit the green button.

Hi CodeAdze. Glad you like it, let's see if I can think of some additional ideas for the future.

One thing I would like to know is how to change the rough grooving cycle so it roughs side to side instead of plunging. eg: feed in on the right side of the groove, machine across to the left wall, feed in and machine back to the right wall (rinse and repeat until at depth). Is this possible in Fusion. Thanks

@@MachinedComponents Start a grooving operation. Go to the passes tab. Make sure Roughing Passes is checked. Hover your mouse over the Grooving Pattern dropdown and you will see the option you want listed there with a visual in the tooltip.

@@MechanicalAdvantage Thanks for taking the time to teach me this, I very much appreciate it.

I think it has a lot to do with machine usage. I still see a lot of lathes being programmed by hand since profiles are generally fairly simple. I also think there are a lot more mills in the world compared to lathes. That being said, I plan to do more lathe content in the future.

Hi Jamie. Any interest in a lathe class if I put one on the schedule? I’m thinking it would be two 4 hour sessions.

Hi Steve. I’m considering putting a lathe training class on the schedule. Probably two 4 hour sessions. Any interest?

Well look at you guys go up there! Or I guess down there? haha Let me know when you get that thing in the shop. Say hi to the wife for me.

Hi Sean. Thank you! Hopefully you found it helpful.

Are you talking about grooves on an end face? If you have a specific example, you can email me info @ mechanicaladvatnage.com (remove the spaces obviously)

Hi Murray. Derived means I want to make a copy of what I just did but change from one machining strategy to a different machining strategy. Rest machining looks at what stock has been removed and what stock is remaining at that point. When I cleared the bore I know the bore is 1 inch in diameter and the drill used was 61/64. So there is about .050 left or .020 left per side. So a derived operation won't know how much material remains. It only knows what selections were used in the previous operation. Hopefully that helps explain it.

@@MechanicalAdvantage Ah, so at 18:03 you selected rest machining so it knew where the drilled bore was and how much to remove, if I understand correctly. Thanks for taking the time to explain! It starts to make sense now.

Hi Murray. Not in this case. I didn't use rest machining at all because I knew that between the front bore rouging and the drilling operation there wasn't much material left anywhere in the bore of the part from front to back. So the finishing profile didn't need to worry about taking multiple passes or anything like that.

It was modeled as a component in the design, not a function of CAM.

Hi Bruno. Hopefully it got you started. Thanks for the comment.

Hi Craig. Hopefully you picked something up.

by putting offset -0.05, isnt that the part model id will be smaller of 0.05?

Sorry, this was a tutorial file that I used that Autodesk created. It wasn't exactly set up to make the part easily changeable or the chuck adjustable.

Hi Nicola. Good news, this file is already accessible by you. You can find it in the CAM Samples directory and the file name is 2X Turning - Quick Release

I’m sorry, but not. Can KZfaq real time caption it in Spanish?

Yep. The g-code is created by Fusion using a post processor to output the code in the format a machine requires.

@@MechanicalAdvantage are you able to view this in fusion 360?

You can simulate the tool paths in Fusion. When you export the code, it opens in an editor where you can view the lines of code that have been output by Fusion. That code can also be loaded into a back plotter (not included with the software) for further verification.

I don’t recall without watching the video, but probably. Not sure the reason, I think I probably assumed that people were familiar with the drilling toolpath.

@@MechanicalAdvantage Looks like some radial holes around one of the thin walls. Great vid though!

Yeah missed those for sure. I was more focused on the lathe toolpaths. Are you familiar with drilling ops in Fusion? If you are, good news they work exactly the same when doing a lathe part. The post tells the live tools to fire up if the hole isn’t on the z axis. If you aren’t, let me know and I can do a follow up video.

@@MechanicalAdvantage I can program them longhand but not familiar in Fusion. Would love a video.
