- This is lesson 7 of 9 on Fusion 360 Turning: Threading - Turning Threads onto the end of the shaft. An introduction to Turning for job shop parts. These lessons are designed to show you the complete "step by step" process of programming for CNC 2 axis lathes using Fusion 360.
Superb Mike! I've just started playing around with F360 CAM for our FANUC 0im - I'll do a video on this one showing the machining. Thanks for the tutorial, it was very helpful, the thread depth explanation in particular was useful.
great tutorial, Thank you! I have the Tormach slant lathe, and have only made a few parts with Fusion on it, manly simple profiles/tapers. The rest I've been doing with their conversational. I came across your video looking for help with internal profiling. Gold Jerry! Anyhow, thank you for videos, and you sir, have another subscriber.
Why did you choose 2mm pitch for a 1.5mm thread? I have been working on getting Fusion 360 CAM to create a threading cycle, but following your instructions results in no tool path whatsoever. In fact, I have tried many variations of settings and I'm getting nothing. I can write a threading cycle on my lathe in 25 seconds. But 2 hours of attempts on F360 resulted in a headache. So, what am I missing?
i can write cycle in less than 10 second. that include calcularing depth and minor dia.
1.5*0.65=0.975 * 2 - 20 =-18.05 SO height P975 minor dia X18.05
Thank you for this video, i'm learning fusion and i find your way of talking very clear to understand.
But did you recognize you leaved 2mm in passes/pitch? :)
Just a comment. In metric countries (Germany, Italy etc) we use the rule that any metric thread depth is equal to half the pitch. So the thread depth of a 20x1.5 Metric Thread is 1.5/2=0.75mm. Tapping diameter will therefore be 20-1.5= 18.5mm. For example, when drilling a hole to be tapped M8 (1.25mm pitch) we use a 6.75mm/6.8mm drill. This works for coarse and fine threads alike. No need for charts. Although not accurate to the hundredth of mm, it is within the required tolerance and will produce excellent threads. We consult charts only for extremely accurate threads, but even so, like any machined feature, any thread must be checked after cutting, either by means of thread mikes or fixed thread gauges. Therefore it is not important to get the correct depth of thread first time, it will have to pass the test of the measuring instrument. Use this rule to pick the correct tapping drill easily. Remember that the old MA, MB thread profile has been updated to the new Metric profile in order to improve the life of the thread cutting tools and to facilitate the life of the operator. In addition, a theading canned cycle automatically calculates the correct depth of pitch, I cannot see why this feature is not included in Fusion 360.
That is a "general" rule of thumb that will get you CLOSE. But that is NOT the correct formula exactly. It will just get you very close. That works fine for manual, but on a CnC machine you aren't getting the correct depth.
Proper Metric thread depth is Pitch X .5413. That's it... If you are doing a 2 pitch thread just multiply 2 X .5413. You will be given the S.T.D (Single thread depth) In metric, so convert that to Imperial. You will notice the depth you get is *not* the same as half the pitch. This has been the proper formula since 1986 in the Machinsts hand-book.
I'm getting a .855 as my thread depth... I don't know where you're getting .81?
When you have time, could you please change the pitch to 1.5?
When the tool finishes traveling to the end, I get an error on my computer since the output collides with the material in the final part. This could be explained by the lead out.
Thank you.😀👋
does the fusin has a stand alone lathe cam or uou need to buy the whole bundle? how do they match you a post processor?
How to change thread direction? Mine plunges into the front of the thread not the back
You did left 2mm on the pitch that why thread look thick
M20x1.5 pro machinist just do depth is 1.5*0.65=0.975
minor dia = 20-(2*0.975)
i do not need charts or even measure thread. i know it go tolerance if i measure tool correct lol

Hello and for multiple threads ? can you have 1 ex. thx :*
Why are you using a 40 year old Formula?
Depth for a metric thread is P X .5413.
The formula you are using was changed in 1986 when they discovered a more accurate and better formula to what I just listed.
@@Cody-ox2uu Hi Could you please provide a link to the value of .5413 I would like to understand this more Thx.
