At 2:21 there's a graphic error of ".2325", which is wrong. It was supposed to display ".257" for the drill size. Sorry for the mix up!

[@Lepp004]

Hi Titan how can I use this technique for a single point thread mill?

[@CNCVMCTECHNOLOGY]

Hello Titan, please explain about external thread milling 1/2"-14 NPT , X and Y starting position.

[@cdquintin3635]

I was going to point that out lol

[@cdquintin3635]

@@Lepp004 no there are many more lines needed for a single point thread mill. I was hoping this video was for a single point treadmill normally programming a single point takes me close to an hour without CAM. I was hoping he had a cool trick like the last 3D roughing video.

[@cdquintin3635]

@@CNCVMCTECHNOLOGY it's the same principle only you're comping in not out, but if you're approaching a hub with clearance room personally I would use a lead in.

[@keathpolyak6469]

Titan, learning manual programming is the best. Thank you for your very generous contribution to an industry that has treated me very well. I am a certified general machinist, working on CNC since the beginning for over 30 yrs. A simple trick or saying I learned for using I&J in G02/G03 is, (remember it as you are the cutter) "Where is arc center to me"? This number is the actual distance (incremental) from where you the cutter are, to the center of the arc that you are programming. Titan, I noticed a safety area that I always use to this day (which has saved me more than you know) is on the G43 line, [ G43 H12 Z5. ] the "Z5." used in conjunction with single block, gives a safe position to stop that a tape measure or gage block can tell you if you are at 5.0" or something is already wrong. Even Z2.0" is better than running in rapid to Z0.10" of within the part. I even have the posts for cam programs changed to output this as a master start point! With the speeds of the machines these days, we all need habits in programming that build in safety to help reduce hitting the parts or worse crashing the machines.

[@frankr608]

I do the same but with a 1." above part or fixture, clamp which ever is the tallest.

[@keathpolyak6469]

@@frankr608 excellent, I remember programming 1.0" or 2.0"...easy to check with gage, or 1x2x3 blocks. I have migrated to 5" or 10", as I am on large format horizontal boring mills now. This as you suggested, is safe to clear a number of obsticals. Programming manually or with cam packages, I feel there must be safety built in to the programs until fully proven.

[@gangleweed]

Never having been exposed to any CNC expertise in my working life and being a retired fitter and turner now for last 20+ years it never ceases to amaze me that a threaded hole can be milled this way.........10 years back I indulged myself and bought a CNC mill from over the pond just to experience the G code moves for fun and get a big kick out of learning to write G code to make the machine do what I want......no cutting anything it's just for the fun of watching the wheels go around.....I don't have parts to make as all my bits and pieces or one offs..

[@TITANSofCNC]

IX eleven thank you G13 is something I have to look into I use a Brother cnc and I believe it supports g13 and g14

[@nathanhood4800]

How about programming a counterbore?

[@Vytor01]

How about starting with the basics since you are teaching CNC. Every student should understand what all of the basic G&M codes do so they can read a program. Although you can get a list and read it, actually seeing it in a program and understand how it is used is a good thing. Tie the codes together and make a part that uses them so a new student can read, understand and see the codes in action line by line.

[@johntunnard7328]

Titan, these g & m code vlogs are excellent. Banking all this valuable information. Moving shops next week, to a company who have the largest number of haas machines in the uk. Been using cam and conversational last 5 years, so these videos are really giving me a way back in. Thank you so much Titan, love you man!

[@adamdolga6485]

Awesome video, like how you explain each part of the g code. Quick question, what diameter did you put in the tool offset?

[@neilmcdonald3473]

This example is basically the same as my technique but i was taught to roll on,roll off with an 1/8 pitch movement in z instead of of a g01 linear movement and also i noticed no cancellation of cutter comp,but hey if it aint broke dont fix it,love the vids,keep it going Titan.

[@johnlarock4486]

When the D value is zero it wouldn't matter, I wonder if the comp would move the cutter off the centerline and leave a line in the thread, I guess it depends on how the HAAS handles that back and forth movement between passes. I noticed he had some code covered up maybe it was the G40s and he cut them out to simplify things.

[@paulcnc4041]

Great video thank you for the info grow up just like u run a shop and learning everything I can

[@Daniel-lq5rg]

From experience, it's usually best to arc into and out of the cut instead of going straight G01 into the part for an improved tool life.

[@shawn01707]

That is correct but for the purpose of training via KZbin it will likely confuse people and add to the complexity of the program. For a Beginner program it is perfect.

Can you do a VLOG sometime on using a SINGLE POINT THREAD MILL? I am generally cutting threads ranging from 4-48 and 4-40 to 10-32. I would like to use a thread mill or thread mills if possible to avoid having broken taps scrapping parts. You whole web presence has been so helpful. Thank you.

[@raider1628]

love the manual programming videos!! could you do a video on how you guys go about aligning the tail stock to the 4th axis in the mill. alignment is crucial to making perfect parts!

[@brianheath4884]

Just use round stock with center drill . Or just find center of index head. Then take half the diameter of tail stock . Now just tap to distance of half the diameter using a indicator. Then indicate tail stock straight. It's not to hard after doing this a few times you will get fast at doing it.

[@kelly63C10]

Great Video Titan. Can you go over why you choose to thread mill vs. rigid tapping with an M29?

[@martinconnelly1473]

Since you have not had an answer I will give you a few reasons that may help. One is that when tapping blind holes you can get a fully formed thread nearly to the bottom of the hole. If you were rigid tapping you would normally start with a taper tap then use a bottoming tap which requires two tools so adds time to the operation since the tool has to be changed. Another reason is that using rigid tapping for blind holes it can be hard to get all the debris out and the tool can jam and then snap off. This is usually a major problem if it happens as the broken tool will be stuck in a hole and can be hard to remove, a thread milling tool is a smaller diameter than the drilled hole so is unlikely to snap and is also a lot easier to remove if it does. A third reason is that a thread milling tool can be used for different sizes of thread, This tool, for 18 threads per inch (0.555" pitch so why wasn't that used in the demo instead of 0.55" as it will produce a loose and badly formed thread that will pass the go/no go test) can be used for any thread diameter with this pitch, a standard tap can only be used for one size. If you had a single point tool it can be used for a range of TPI/pitches and diameters. This means that if you have a tool changer with limited spaces you can use a single threading tool for many different thread sizes where standard taps would take up many stations. Fourth reason, you can produce left and right hand threads with a single thread milling tool. The final reason I can think of at the moment is for large diameter threads. There are two problems with these, one is the torque required goes up to the point where it may move the workpiece or stall the spindle on some machines and the other is the cost of large standard taps is usually high compared to a thread mill. Hope this helps

[@caploader111]

Why no G40 to cancel cutter comp? Is there a parameter to avoid an alarm? Im thinking that if theres no value for D4 there will not be an alarm but if there was a value in tool geometry the machine would have alarmed out.

[@chrisranly5952]

Been looking for a while... Titan love your work, show me how to program an NPT thread with a single point thread mill. I use edgecam and it doesn't have anything for this. I'd like to just program it by hand at the control. Can ya do it??

[@woodwindfixer]

Re: cutter comp. the ancient machines at my school (fadal) require a 90 degree x or y move to the first cutting plane (larger than the radius of the tool) to engage cutter comp. it doesn’t look like you needed to do that with your controller. Am I seeing/understanding this correctly? I know all machine controllers have their own ways of using/requiring the input to some extent.

very nice video. we don't need to put a G40 going back to the center of the hole?

[@mactec98]

Titan, If you could go over manually programming a 82 degree countersink. A lot of haas guys have told be it can’t be done. I don’t believe that. I’m thinking setting up a sub program would be the place to start and knowing the change in the radius for each change in z. Not sure how to format it. Thanks for your dedication to the trade

[@davemcclue6226]

Hey Titan, thanks for all the videos. I’ve tried using this exact code on my haas at my work, but I get a compensation alarm. I have the correct information in my offsets page, is there a setting I need to change to get round this. Also no G40 either, how does that work. Relatively new to this, so any help would be appreciated. One last thing, I thought you have to comp on at least half the radius of the tool. Sorry this is such a long comment. Boom!!

[@timdavis5707]

Dave, you can use as little as a .0001 comp value when using the (hole dia. minus tool dia.) / 2 formula as long as you set your dia. to zero in the offset page. Hope this helps.

[@davemcclue6226]

Hi Tim thanks for the reply. I didn’t know that was a thing you could do. I always thought you needed correct tool info in geometry page. What about not needing a g40?

[@chasen4l]

I just barely saw this trying to figure out how to do thread milling.. The way titan explained it was as if you are programming without tool compensation.. that is why there is a tool compensation error.. take out the g41 and try the same code

[@robindriscoll]

Also, how small a thread can you make with a thread mill? My smallest hole is 4-48. I am cutting into M42 tool steel and would like to thread mill it instead a tapping.

Amazing wow But i have dout were you put in cuter copnsetion cancelled code (G40) and another one is. What's the actual diameter of the tool and what input on D4.

[@manmachinemake3708]

If you don't use .000 on the tool diameter offset, You get 369 Cutter comp alarms. I think the fact that the offset is .000 means you don't need to cancel the G41 since it's technically 0 He would have done well to include that bit regarding the actual offset he used and why.

[@manmachinemake3708]

Set your Cutter offset to .000 and the rest of the numbers as calculated, then run the tool .200 above the hole and see if it works before dropping it in and crashing a $250 thread mill. He fails to mention the offset needs to be .000 to start

Thank you so much but I've never used a L value? I've been learning so much from your videos and made me such a better operator could you use an example?

I believe that you missed z-.055 end of the pass. finish pass started at .165 above the started depth....
