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.
We program at the lathe control panel and when software is used, operators freak out because it looks different from what they are use to. We use canned cycles and simply edit existing programs as needed. But for more complex stuff we'd like to use software of some sort. But again it doest post to what operators are use to seeing so they freak out.
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.
16:26 why didn't you use a derived operation so that the boring tool knew how much material remained? Perhaps you can't follow a drill with a boring tool? I'm never sure why derived is used and sometimes not. And then we have "rest machining" - how does it differ from derived?
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.
somewhy i dont have any affect on toolpaths by cheking on Tangential extention, it doesnt change the distanse between the part and the starting point in profile roughing and the toolpath falls down at front in the profile finishing. However, if I do same manipulations in original tutorial file, changes do affect, what may be the problem?
Thanks for the clear tutorial! Have you had any luck getting Fusion to post your roughing as canned cycles? I can’t seem to get it to work with any of the posts that Fusion provides.
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.
why do we need to put an offset for the inner radii. Cause don't seem to understand the purpose of it. When I tried to put a value, say -0.01. The tool couldn't do the finishing for the drilling leftovers. 18:45
I bought the Rapid Turn with my Tormach 2 years ago...I'm thinking it's time to start learning how to use it. Your vids are always a good place to start!
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.
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
Thanks Kevin!...this was a helpful overview. I'm just getting up to speed using Fusion CAM on a Trak 1630 lathe. There doesn't seem to be much out there on face profiling with the lathe in fusion. Any chance for some content that covers face profiling? Thanks for your efforts, and keep up the good work!
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)
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.
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.
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.
Good day, Is there any example of turning a casted or forged part, that is, the part is not machined out of a round billet, but from a casted or forged part. The roughing will then follow the casting profile and avoid to cut in the air. Hope I've been able to explain myself. Regards, Bruno
Super helpful. Thank you for posting. Would love more Lathe videos from you!
Please just like Steve said keep making lathe videos 100%likes.
Great video, lets keep the lathe content going, Video Idea... stock parameters, lathe templates.

very good - thanks - helped on internal bore
how did you get the chuck to show next to the model?
It was modeled as a component in the design, not a function of CAM.
i want to create a setup and having issues in setting up the axis X& Z
can you help me out?
Great video! Thanks for posting!
How do i add champhers to a part is this done in the design phase?.

I can’t get my boring operation to post a canned cycle, even with it being selected. OD roughing posts canned cycle just fine.

Excellent video! How about some millturn videos? Thanks!
Klasse! THX
Awesome video. I learned something new with your finish bore going back to front
Excellent. That’s what I like to hear.
How do I change out the part in chuck with my part?
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.
What I love fusion for is its repeatability)
Excellent video; thank you! I was rather hoping we’d get to see the part cut for real at the end!!!👍😁
Awesome Man! Keep making lathe videos!!
Hi Steve. I’m considering putting a lathe training class on the schedule. Probably two 4 hour sessions. Any interest?
Thank you so much for making this video

by putting offset -0.05, isnt that the part model id will be smaller of 0.05?
I learned so much from this video, Thank you
I bought the Rapid Turn with my Tormach 2 years ago...I'm thinking it's time to start learning how to use it. Your vids are always a good place to start!
Very good Kevin this will help me out to star making programs on fusion Lathe and stop using bob cad software.
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.
can i know what post did u use for nc code?
Is this video available in other languages? Like Spanish?
I’m sorry, but not. Can TH-cam real time caption it in Spanish?
Excellent tutorial , thanks Kevin. More turning videos please.

@@MechanicalAdvantage Thanks for taking the time to teach me this, I very much appreciate it.
Is it possible for you to share that component so I can use it for teaching so students can see the chuck fro better understanding.

Awesome video Kevin! We are close to pulling the trigger on a Haas TL2
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.
Thanks for the video!
Hi Bruno. Hopefully it got you started. Thanks for the comment.
Thanks, Kevin Don't see too many lathe tutorials.
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.
Quite possibly the best tutorial on youtube. I dont even have a CNC lathe!
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
Would you be able to get the CAM code which would be sent to the CNC?
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.
Fantastic video thankyou!
Hi Sean. Thank you! Hopefully you found it helpful.
Thanks for sharing!
Hi Craig. Hopefully you picked something up.
Didnt we miss some drilling here?
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.
Good day,
Is there any example of turning a casted or forged part, that is, the part is not machined out of a round billet, but from a casted or forged part. The roughing will then follow the casting profile and avoid to cut in the air. Hope I've been able to explain myself. Regards, Bruno
