I produce 99% of my turning progs at the machine or in a text editor in iso G code. Your canned cycles and a little (or in my case a lot) programming knowledge is really all you need. You can also save basic templates and edit them to suit. I use Fusion mainly for milling, then it really comes into its own.
Thanks John, I'm not a lathe guy either although I have a CNC converted Grizzly, Seems like it's harder to get my head around. I am always appreciative of any help I can get programming the lathe. BMac
The default for the clearance height on the boring toolpath can be set to be relative to your inner radius with a negative value by default. For example, I like my clearance to be about -.05" from inner radius.
Hello, thanks for the tutorial, is it possible to make the turning start from the outside in? I need to use a counterpoint and the trajectory that it generates collides with the tailstock ... Thank you!
Here is a trick we do, on parts like this we actually do the big side first since its close to stock size and use a tight 5c for the stock, turn the big feature, flip it then finish the back feature, this way we avoid having half done parts laying around! tryi it out!
You leave alot on the table as a job shop by focusing on mills. Motion transfer parts are most commonly cylindrical and often have stringent concentricity and circularity requirements that are sometimes not met by a mill without resorting to things like boring heads. Right now you're looking at 3 setups to complete the part (turn, axial holes, radial hole), but you could eliminate 1 setup with an ST-20 or 2 setups with a DS-30 with live tooling. 8 minutes per part in just turning would be cut down closer to 2 minutes with a professional grade lathe. You may not like lathes, but if you were to hire someone who loves lathes, you could expand the capabilities of your shop and provide more value to your customers...which is a core component of Lean, is it not? Why would a customer want to go to you for mill work and another shop for turning when the other shop is competent in both? How does that best meet their needs?
Kenneth Higley You'd be surprised how much more mill work there is vs lathe work lately. You can certainly maintain a business strictly on mill work alone. And a CNC mill can make short lathe parts easily. A lathe doesn't make milled parts too well unless you spend the $$$ on live tooling and Y axes
In my experience, the nature of work varies depending on the location. For here locally, the shop I work at usually employs nearly twice as many CNC mill men as CNC lathe men. The mills are somewhat nicer, while two of the three lathes are old and dilapidated. The three mills run almost every day, while typically only one lathe runs every day; the other two run every few days. I suspect John's world is similar. A nearby shop is the same way, if not moreso. They have three lathes (one being a Swiss), while they have six or slightly more mills. Then you look at a shop like where Adam Booth/Abom works, and it (seems) to be a vastly larger percentage of lathe work! Funny that way. I guess it depends on what work comes across your table. If folks send you 75% mill work, you oughta have more milling capability than turning. If you invest in a fancy new turning center without the work to back it up, that can be scary. Sometimes you gotta keep to your strengths.
Occams Sawzall yes, so you can stop wasting a ton of time on setups. Setups add exactly zero value to the customer. There's a very good reason live tooling is the most popular option on an industrial lathe.
Could you help with a lathe tool path? I somehow created a finishing profile cut on a lathe with two diameters that retracts in X and before a second diameter cut. I like this because it takes the backlash out of the X travel. I can't recreate that tool path.
Would it make more sense to just hand program this simple part instead of using fusion? I just wanted to know your thought process on approaching small lathe jobs.
I wish we had local compaines with the same level of support from suppliers like McMaster Carr and Online supplies like Alro in Australia. Would make life sooo much easier.
We can’t seem to get through a decent cam program in fusion without it constantly freezing and crashing. It’s nice for drawing models but the cam side of it is not so much. We’re looking at a alternative cam program for the lathe right now. We have Gibbs for milling side and it works well it’s an incredibly powerful tool.
Glenn Edward in my experience the modeling is very weak along with lathe CAM But fairly strong for milling. Not sure why you are crashing but you might wanna give tech a call cuz I’ve been using F360 since the beginning and only had it crash twice.
13:53 are you sure. it calculate all based on your tool that has spike. i try simpler OD roughing. it takes me 2 hour do get simulate without RED RED RED going in part (why it go in part) model is there tools is there stock is there. CAM isstupid. it take 10 seconds write that gcode hand. it is 10 lines. CAM output 1500 lines.
Do you think it possible to use the Lathe CAM with a 4th axis and a router head instead of a single point lathe tool? X & Z in my case...and then possibly cut threads with a 60 degree router bit?
I haven't tried Alro for metal yet. I usually get good prices with metalsdepot.com or onlinemetals.com for smallish quantities in steel and aluminum or hudsontoolsteel.com and get their oversize tool steel.
Hey John - any idea how I can get Fusion to cut on the negative X axis? My tools in my turret work fine but I'm trying to use a boring bar on the QC post and it WILL NOT cut in negative X! Thoughts?
Nice video! Do you have any easy trucks to program in an offset when you're lathe is cutting with an unintended slight taper? Thanks, your great are great education.
@@jasonlanning2394 Great to hear. Not done anything long in mine yet, but my very similar manual lathe cuts slight tapers, quite annoying if you're looking for accuracy. Hopefully my cnc lathe won't be the same.
You have a new fan. You were recommended from AvE..and as I mentioned in an earlier post....I love learning from energetic people who genuinely are excited about what they do....I'm a noob to machining coming from blacksmithing and woodworking and because I"m a home machine enthusiast, bought a combo mill/lathe...not anywhere close to the quality you have. For me, its perfect. Do you ever have classes?

there are contours which are rather hard or time consuming to program by hand
@@TheKeule33 agreed 👍🏻

Just spent two days on a course for HSM works....this makes so much sense now...
OMG thank you so much for the "spun Profile smoothing" tip, I thought I was loosing my mind. Excellent detective work John!

Hey John, to reduce the amount of screen artifacts you get with fusion and other CAD software, grab a Quadro graphic card.
Any graphics card. A nvidia gtx 1050 handles it like nothing. Doesnt take much.

Really appreciate this service. A question: why does the program name have to be a number (instead of a name) in order to export the .nc file?

What I liked was "you need a lathe!.... and then you need to add a bunch of milling options to said lathe!!"
😆

Because even lathes know mills are better.
Could always just get a turning option for a mill. 😝

Great stuff, thank you. CAM and excel info was great, I will be viewing several times.
What if you were using a tail stock and live center. How would you set the program up to where you wouldn't crash into it?

thank you so much..
Hi, could you please do a dedicated video on drilling on centre in the lathe with fusion 360.
Can we use FUSION 360 with Tornos Fanuc 32i?
Nice video! Do you have any easy trucks to program in an offset when you're lathe is cutting with an unintended slight taper? Thanks, your great are great education.
@Jason Lanning Did you ever solve this?
@@thomashenderson3901 I was not able to, I found a setting in my machine to make the correction.

Shout out yarde metals, drop zone I use all the time
Your 1/8" left on parting will not work, as you have drilled it out in a previous operation.
Exactly what i was thinking.
But, in my fusion 360 there is no CAM opinion show
I wish Fusion were better at programming lathes, it is so damn fussy and particular about you turn the part.
And it doesn’t work with gang lathes and right hand cutters upward running ccw spindle. Lots of issues like that besides it crashes too much.
Ya, lathe work!!!!! Woooo
I know your not a fan.....
6:69 75 hour its profit. if machine not do anything. works if client pay for it. or he do it them byself free
please never say "caming up" again
