John. If I could make a few suggestions when you spot drill for a tapped hole use a spot drill a little bigger than the thread diameter. Say for your 1/4-20 thread .3125 or .375 and spot .010-.015 bigger than the thread, in this case .265 dia. this chanfers the hole as well as spot drills for the tap or thread mill. Also if you are going to do a lot of thread milling it pays to invest in the thread pitch gage to check the thread size. The reason the bolt is loose in the tapped hole is not the hole it is the bolts clearance. if you use a bolt to gage your holes they will be to small. On the thread milling profile you could use cutter comp, than you can control the size with a offset at the machine not with having to change the program.

[@Disillusioned_one]

I'd sit and watch your videos all day. Nice one John.

[@DStrayCat69]

Sheesh! Now I don't go out on Friday nights... You're really cutting into my drinking time... lol But I luv it :-) Great little video

[@nailedart4431]

Use advantage of CNC for tapping, this is great. Again thank you John for another great video.

[@EZ_shop]

Finally, I can dust off my single flute thread mill once again! Thanks John.

[@MOREENGINEERING]

Oh crap! I missed this one when it came out. But I got it now......another great Fusion 360 session. Thanks heaps.

[@Fromeco]

Figures! Spent 3 hours last night trying to figure out how to thread mill with a Lakeshore single thread 4 flute. You didn't cover it, but did mention it.. If you want to use the single thread type bit you have to select Slot Mill (which if you ask me is totally not intuitive), (NOTE: Selecting chamfer mill will give you an accurate tool rep. but it will not work (3 hours of wisdom on that one)).. Huge pet peeve that they will not do anything about Thread milling in Fusion 360. I guess not many people do it, if you have to thread bunches of stuffs it is the only way to go, specially if you need really really accurate tight threads. Great Video John

[@Fromeco]

+NYC CNC Crap that figures that seemed like it was so far out the the rehlm of possibilities I didn't even try it. I just cut a new water manifold for the Tmach, cut some 1/8th pipe threads. To get it to come out right, I had to have the pitch in there .03736 with a pitch diameter offset in there of .06 which took several tries to nail down. I think I am doing it wrong? And what is a pitch diameter offset?

[@KoenBrader]

This was exceptionally useful. Thank you.

[@ericbeckers2673]

Again a great video. Much appreciated. Have a good weekend

[@mountainmanfab]

Have you ever looked into using thread forming taps for your smaller holes? No chip loading to worry about and thread formers are a good bit stronger then traditional taps so less chance of breakage.For larger holes thread milling is definitely the way to go!

[@proteummachining]

Another important note to speed up and improve your threadmilling, if you calculate how far you have to travel radially you can divide it up better and use less passes. Since your major is .250 and you are drilling .201 you only have .0245 a side to take (probably even less with the drill not drilling on size). That's why your first 2 passes didn't even cut and the other 2 were progressively heavier.

[@proteummachining]

Also great video! Can't wait for custom form tools as well

[@matthews8704]

Great video. I finally convinced my boss to get the shop some thread mills after some very inconvenient broken taps in parts. When a tap breaks in a part it can be very difficult to remove and might scrap the part. I like using thread mills for blind holes or threading very hard materials.

[@corleythomas]

Hey John. Very informative videos. Good luck with your projects ...

[@wagglebutt]

Nailed it. Great video.

[@SublimatedIce]

Awesome Videos. Keep them up!

[@ruben-yrcnc2029]

Very nice John!!

[@GregsGarage]

The slo-mo was a great touch John.

[@Impyman18]

+NYC CNC Felt like an 80's movie with the slow-mo

[@GregsGarage]

I was thinking more like Yasmine Bleeth but whatever!!! :D

[@DonDegidio]

John, Nice video. I like watching CNC machines at work. :-) On the first tapped hole, does the tap have a grading for the fit. On hand taps, you can get them in H1, H2, and H3 with H1 being the best fit for the bolt.

[@uzkanda]

To bypass incremental with of cut you can split one operation into many manually setting stock to leave in each one. also do you have a video how correctly lead in, ramp in and plunge?

[@craigsmachineshop2040]

Wow, perfect timing John! I get my tension compression tapping head from Tormach tomorrow.

[@craigsmachineshop2040]

+NYC CNC - Help Please. I followed the tapping part exactly but Pathpilot is saying "Unknown M-code used: M29" I have the most recent version of Pathpilot and the Pathpilot post processor.

[@craigsmachineshop2040]

+NYC CNC - Sorry, I figured it out. Had to have Pathpilot post processor and use tapping not right hand tapping. Worked great! Thanks!

[@chillierdavro]

Nice video loved the slow mo action :)

[@k5at]

Awesome, John. Makes me wish I had a Tormach!

[@jedbramley5951]

NYC CNC

[@TheWidgetWorks]

If you have a hole modeled to the tap drill diameter (or any other diameter) then you can use the pitch diameter offset to correct the offset of the cut.

[@KerryHarrison-Woodturning]

What are you using for a Fusion 360 Path Pilot post? I can't seem to find one. Thanks

[@ambadassonawane6586]

Great video

[@Tigglebitties]

Have you done an update to this video? I think 7 years later fusion wjll handle thread milling tools

[@sebastienbily2331]

Hi from France, The one Thing I hate with being a subscriber of your channel is how it makes me feel that my shapeoko 3 is a toy... For the rest boy do I learn ! Thank you for your time spent sharing.

[@lensherman6242]

Maybe dumb question, but why is the tap wobbling when it's not in the hole? Seems like it should run true. Does the Tormach tapper also have side-to-side allowance as well, so the tap doesn't have to be perfectly centered?

[@dustinwalden7091]

Can you get the fusion folks to let you set height presets? I like to use reference height of .1 vs their R.2. Also on the drill break thru they need to calculate from the cutting edge and not the point. That's all for now.

[@jarisipilainen3875]

5:48 yeah. once you have makro that work it works allways. no need cam. even with multiple cuts. part is here tool is here stock is here. cut it. thats how my makros work. no need cam. how but square pocket that have round on midle. or round pocket that have square inside or even any feature like hex. pocketing everything else leave hex. its funny but it will be 1 line code. do that operation vs multiple hundreds on cam.if pass redred collision error

[@Duraltia]

@03:35 That Speeds & Feeds Spreadsheet... Is it of use ( and publicly available ) for other materials than Metals like Woods and Plastics? I just ordered an X-Carve last week and while I'm waiting for it to arrive in two weeks or so I'm learning about it and Fusion 360 which is going well. What worries me so far is my utter lack of knowledge on what to keep an eye out for when it comes to using the proper settings for the various Bits / Materials.

[@flyincivic]

John I'm in need of a generic post for an old Okuma lathe ( 2 axis). Who would I need to contact for that in Fusion 360? Thanks Les

[@makirompe]

can you use the same trick for external thread milling on f360? such a good software but form tools are a must have

[@makirompe]

Oh you replied me here too. So kind! The first two examples that cross my mind are dovetail cutter and hobbing cutters for splines and gears. Or the strange cutters used to make broaches for gun rifling. I know they might be off the goals Autodesk had for f360, but it'd be nice having them.

[@mazzullaoffroad5562]

John, how in the hell do I create a ANSI tap!

[@BarsMonster]

How do you translate "Poker factor?" 8:22

[@ChrisDePrisco]

Pucker factor indeed, I found even I was tensed up while it was running; I've seen what those things cost! lol

[@X_Studios]

This would be a good update video

[@alexgroeger326]

John, If you had your stock mounted on a rotary table set to rotate around the Z. Could you lock the spindle and feed that tap down at 20 ipm, providing of course your rotary table could get to 400rpm? But seriously, you probably could rigid tap like that at say 5ipm and rotate the table about 100rpm, right? I was hoping to see something like this. Perhaps using a 4th axis rotating about the x or y maybe? Haven't seen much information about tapping with a fourth. But it's synchronized 2 axis interpolation so in theory, it should work.

[@sunshinecoastmakerspace3500]

John, I use the On-line thread milling processor on the Guhring website. It has a nice easy to use graphic interface and gives options for multiple passes; www.guhring.com/Tech/ThreadMillCNC/Default.aspx It is designed to support the Guhring products but you could make it work with what you have easy enough. Then copy & paste the code into your program where ever you need it. I don't know if Tormach has the capability, but you could write a custom macro for thread milling and assign it to a spare G-Code. I've been using Haas machines and it has this capability, but I think they really should provide a factory G-Code for thread milling. Using G02 and G03 uses a lot of code to complete a simple operation.

[@matze1508]

why do you still not chamfer your threaded holes before tapping/thread milling? just center drill a little bit bigger than the nominal diameter of the desired thread and boom chamfer and centered in one pass. here in Germany every apprentice learns it this way. always chamfer before threading!

[@tomsplace239]

Where did you get your excell sheet from with your speeds and feeds?

[@tomsplace239]

Nvm I found it in the lakeshore carbide tooling series.mi knew I saw it somewhere. Thanks!

[@marshallengland6527]

Hi John, Is it possible to print out / save a Fusion 360 part to a 2D drawing? if so how ?

[@marshallengland6527]

You are too good to be true John. Oscar nominee for video shorts!!!

[@tacitus101010]

Nice macro shots!

[@CncObsession]

A thumbs down? Somebody has some splaining to do!

[@Impyman18]

+CncObsession Brad @ TacticalKeychains.... I kid I kid :)

[@molitovv]

Hi John, just an idea but it might be awesome if you made one of these? I'd love to see the process, would be an awesome paper weight/talking point for your office. Cheers for the videos! kzbin.info/www/bejne/i57agp2rf9mnrc0

[@LumaLabs]

Tried a form tap yet? Once you switch to form taps, you will never use cutting taps ever again!
