How To Model a Feed Screw Or Golf Ball - Fusion 360 Tutorial -

[@richardturnnidge]

I thought (but may be wrong) that a golf ball was more like a geodesic pattern, but with dimples, rather than a rotation around a vertical axis. How would you tackle a repeating pattern for something geodesic? Like some of the large green houses or botanic garden domes (eg. Eden project, UK)?

I don't want to learn how to make a golf ball. But I do like how by teaching me something I don't want I learned things that I need to know. I love the idea of making a design without making a single sketch . I think I will try that challenge. Keep up the great work Lars

[@cadcamstuff]

That is awesome to hear Sean O'Brien .Thank you for watching the videos

[@craigmck7271]

Hi Lars, Thanks for the help on the split / cut / spring washer :) Normally I would use your closed suggestion, but in this case it was an exploded view and it looked better with the open washer. Although now you have shown the coil function I could make them with the centre mark already in place. So another helpful video. Thanks again, Craig

[@cadcamstuff]

Hi Craig McKee Thank you for watching! and for the topic!! Have an awesome day!! Best, Lars

[@caspar3152]

Excellent Tutorial. Thank you for sharing, Lars

[@jpmcsweeney7156]

Not a golf ball, because all dimples are spaced proportionally, but you did a good job anyway. You got the point across!

[@almonster2066]

Thank you for making these videos! So helpful!

"CAD software doesn't like zeros" Can you elaborate on this please? Thanks 👍🏻

[@kevCarrico]

great format - great stuff - great video, thank you!!

[@cadcamstuff]

Hi kevCarrico Thank you for watching!!!!! Best, Lars

[@johnhildebrand8635]

Once again for the awesome video. I have learned many tricks and techniques which have improved my efficiency. I was wondering how you would project a sketch on to the curved surface so that i could make the indent pattern on the ball custom. As if i could draw on the surface of the ball with a specific design. The space mouse is wonderful.

[@cadcamstuff]

Hi John Hildebrand Thank you for watching! I need to do a video on the different projecting tools :-) Coming soon!!!

[@bharathrajashekar834]

sir , can you teach me double coil feed screw design. Generally its used in rubber industry for extrusion

[@edman2740]

Please do an advance tutorial of some-kind where it really imposes you a challenge. That would be awesome!

[@cadcamstuff]

Hi Ed Man Thank you for watching! What would you like to see?

[@edman2740]

After several days of thinking, I finally made up my mind, and found what I think is a good challenge, the front ailerons of a F1 car. Do you think, you can make that possible?

[@varazir]

I didn't know about the selecting faces inside a body, thanks To show the Pattern on Path better is to use a cylinder if you do this again

[@cadcamstuff]

Thank you Daniel Söderlund

[@dtesta]

Lars! Your videos are awesome. However, I would like to know how you would model a nut that fits a "lead screw" for 3d printing. As you want an easy way to change (and test) different tolerances. Just picking a lead screw and nut from McMaster-Carr will make it too tight. Just scaling it up 1% (or so) in the slicer is an ugly solution in my opinion and probably will not even work for more advanced lead screws like with 8 starts.

[@JustAlb1n]

Daniele Testa you can create a hex body then use the lead screw to cut in to the hex body and then select the inside of the nut and hit Q on your keyboard then drag it to the tolerance you want.

[@dtesta]

Hi, how to model variable pitch feed screw?

[@kobalasteriyan378]

The dimples on the ball aren't evenly spaced as on a real golf ball. How do I space them evenly, as a dodecahedron would be?

[@nanovac]

Awesome as usual! Keep up the good work! :)

Thank you Nanovac AB

What is that device mounted on the shelf on the wall behind Lars?

[@pratap3369]

I think it is a CNC controller

100% good man ty

[@landlockedviking]

Good stuff! How about for a variable pitch feed screw and caming for the lathe? Pretty please... :)

[@cadcamstuff]

Hi landlockedviking Thank you for watching! Yes, that is on the list!!! Best, Lars

15:13, 1/8 of the ball.

[@johnbickford9221]

Most golf balls on sale today have about 250-450 dimples. Looks like by my math yours has 107 but who's counting. I guess I am. Looks good though.

[@cadcamstuff]

lol, John, proving how much I know about golf :-) Thank you for watching!

[@johnbickford9221]

I know nothing about golf either (mini golf excluded). I was just doing some research about it after watching.

[@edizfer7946]

DO more TUTORIALS on the newer version!!!!!! please, u just disappeared ..

nice, i learned something new ,im starting to like fusion more and more, im hardcore Inventor Lars, what are you doing to me.LOL

[@garywood9119]

No success in downloading and installing Fusion 360 on my MacBook Pro, Mojave OS. Autodesk help, knowledge base, Etc. Useless. Help?

[@hotcols1171]

This is 4 months old, but have you got this sorted?

[@hannibal1212]

Split washers are all lock washers but not all lockwashers are split washers.

[@cadcamstuff]

Hi Hannibal Thank you for watching! Sometimes I get so easily confused :-) Have an awesome day! Best, Lars

[@jarisipilainen3875]

8:32 cool. now make it variable thread and slope and make that is posting under 50lines code i hand wrote makro LOL

[@fosscadbot5439]

For the feed screw, why not use the HelixGenerator Addin ( github.com/tapnair/HelixGenerator ) to make a helical path and then sweep? Is there a better way to make a helix path without such a plugin?

[@cadcamstuff]

Hi fosscad bot Thank you for watching! Well the plugin is written by one of the smartest people I know :-) I think I need to do another livestream on this topic Best, Lars

[@jbpan8669]

非常棒的视频

[@hotasfireph]

We call that a lock washer.

[@jarisipilainen3875]

26:42 you just did it use coil lol

[@vernonleeper7788]

LOL crazy

[@jenspetersen5865]

Sikke en skuffelse Lars! (What a disappointment!) I was exceedingly happy when I saw that you would make a tutorial for a feed screw, but very disappointed that this was only covering simple revolve profiles - ie - cannot transport solid bodies. Any machine where you transport bottles, cans, screws.... you name it, needs both the machining and shapes - a company LD Cad builds plugins to Inventor for making this kzbin.info/www/bejne/namwdISEbLOloNE, but your video here does not even come close to being helpful for designing something like this. Also TopSolid and SolidWorks have great videos out there - TopSolid - very advanced and SolidWorks a lot of manual work but great results. I hope you will make a video of how to do a BOTTLE feed/timing screw.

[@DeadlyRabbit]

I found it disappointing to see what was done with the feed screw as well, I make feed screws at work on a daily basis for the food and beverage industry, make the blanks, program and setup the screws in a cnc mill. It is understandable that what was shown is limited to what is actually needed for a feed screw (other names are timing screws, or scrolls), not many companies are needed to supply the demand for them, even in the company I work at only a few people fully understand all the aspects to them. The person that asked for a tip on how it is made should have given more of a description and explanation of what they wanted, outside diameter of the screw, root diameter, length of screw, go with a round package to make it simple and what the diameter of the package is, how many sections, what the infeed pitch and discharge pitch would be to get the basic idea of what would need to be done. Without all that info it would be difficult for someone that doesn't understand what is needed for a feed screw to come up with numbers.

[@cadcamstuff]

Well, I am so sorry about the disappointment. This is what happens when someone does not totally understand what they are doing :-) lucky for me....This gives me an opportunity to do another livestream :-)

[@DeadlyRabbit]

Yeah it does, feed screws are so specialized that companies make them using custom built machines with custom software. With custom software they can be programed including the tool paths in minutes, using regular CAD/CAM can take a day or longer for a basic package in a simple feedscrew. A basic round pocket while being machined with a ballnose endmill doing a top cut with a 4th axis should be possible in Fusion. Doing a side cut with an endmill is probably too complex.

[@JulioCesarSilveira_adv]

@@cadcamstuff - your videos are too long, not objective, your language is complicated to understand for non-Americans. It would be good to try to improve diction, to articulate each word individually. Your personal presentation matters little. It's constructive criticism, unless you're not interested in audiences outside the United States ...

[@henuli]

I can understand him and I'm non-American, non-native speaker. And about the length, I find it better that he shows every single step to create things. There's enough 1 minute "tutorials" with captioned shortcuts to magically do stuff with steps missing on editing table and then you end up googling the steps not shown. I've been doing 3D modeling for about 15years and just recently started to use Fusion, and I get useful tips and tricks from every single video I watch. Thanks for all the awesome stuff, keep up the great work
