True with so many things.

Cut. Measure. Adjust. Cut. Done. Kidding aside, it depends on the accuracy of your boring head. The one he is using looks pretty course compared to some I've used. I've used a D'Andrea head that moves .004" dia on one full dial rotation. In many materials you want to avoid "nibbling" away in tiny increments because it can work-harden the surface of the hole. This causes the cutter to deflect away from the work piece, to the point where you adjust and adjust and the hole stays the same size, until it gets enough pressure on it that it takes all of your previous adjustments all at once, causing the condition you described above ;-)

I'm actually a bit surprised it didn't go oversize since the second cut was a lot lighter than the first. You guys obviously know your tools/material though! If there was 0.008" material i would have gone .004-.005 radial cut first, then adjusted and cut the rest so that the cuts would be equal.

[@DawGGG85]

Exact what I do, it might be a little slower, but damn it's accurate!

[@zzzzBadBoyzzzz]

That hole went over size. That 1.0000 Deltronic certainly had more than .0002 clearance... and the 1.0002 NO GO pin was never aligned properly to test the fit.

[@The0_oface]

Got laid off couple months back but the learning never stops.. thank you titan and everyone!

[@DrW3ak]

In germany, one of the first things we learn using a boringhead is to take the play out of the dial, this generally means only adjusting the diameter up and if we have to adjust it dow, to first spin the dial backwarts for one round and then set the final diameter while adjusting the diameter up.

[@TITANSofCNC]

Agreed, which is standard if your boring head mechanics have play.

[@markmall5757]

That’s correct and even place some pressure against the bar so as to have a reliable adjustment all the time especially when using shitter boring heads. This man is using a fairly high end head so results are easier to achieve . This video has ignored spring cuts and amount of material removal of course.

[@eliascastillo1641]

On the boring head I use at work, locking the set screw moves the bar a thousand or two after you adjust it . It’s nice to not have to worry about that.

[@P8ntbaLLA56]

Bore gauge would be better than the gauge pins. Because you can "see" run-out. Gauge pins are good to know the smallest part of the bore, but do not tell the whole story. But I'm knit picking. Great work.

[@Factory400]

I don't think that is nit picking. Qualifying precision holes is difficult and Deltronic pins may or may not get you there.

[@UshouldTryReality]

Not really, most are 3 point contact and 2 people or even the same person often can't get .0001" consistency! For speed and accuracy pins rule, if your process is likely to produce holes that are not round production pins have relief ground on the no-go pin for 2 point contact. The pin bouncing in the hole proves it's round and precision holes always get a pin or shaft during assembly not a bore gauge!

[@calizess]

QC can also be a contactual condition. If the client is happy with gage pins - so be it.

[@P8ntbaLLA56]

@@calizess agreed. It was stated in the video that's the best way to measure a hole and I don't really agree because it doesn't tell you the whole story.

[@jeppoification]

An interesting approach which obviously works well for you, I'd love to know how much the initial cut was... Personally I'd leave around 0.2mm on, set the boring bar on the bore, take a 0.1mm cut, measure then take the rest... its been a while since I've been on the tools but I got pretty good at boring there for a while, never had the probe to be able to try what you've done here but even so I think I'd try to set it to take a semi finish then finish cut. The reason being is lets say you set it to 25.4mm but you've got a rough hole of 25.2mm. Your first cut would be 0.2mm approx and then lets say you have 0.02mm left, if you adjust your boring head by 0.02mm you run the risk of cutting oversize as you'll be taking 0.02 plus a spring cut... this is why I always try to keep my semi finish (trial finish) cut and finish cut the same DOC... you can also adjust you rpm to suit so your cutting forces are kept the same between semi and finish cuts.... High production I would approach different as well but for what looks like a 1 off part in titanium I'd have no problems explaining a trial finish cut to the Boss...

[@Chazzyp100]

You'd be better off just interpolating the bore, you can still achieve that limit and it is less setting up

Love the videos keep up the good work!! For those of you who can't rely on your bore dial just use a tenths indicator attached to your table. Sweep the highspot of the boring bar and adjust accordingly on the Radius.

[@dmtjuulpod]

Pins are fine for measuring a bored hole, especially if the tolerance isn't super precise and if you are on time constraints but I wouldn't go as far as to say they are the best way. Measuring on a CMM or using the in machine probe is much better because you can more accurately measure the size, circularity and taper between the top and bottom of the diameter.

[@TITANSofCNC]

[@rayballard8152]

Deltronic pins are perfectly acceptable for checking +/- .0005" tolerances. When you get down to +/-.0001 you need to use air gages or something like a Sunnen bore gage in a temperature controlled room/area. I use to do a lot of these kind of tolerances on a Sip Jig borer. Another acceptable measuring device for +/-.0005 is a Tri-mic or Intrimik. Like some have mentioned before, you need to be careful using pins for checking holes because they are only as accurate as the roundness of the hole you are checking.

[@steveh8724]

Sure, out-of-round will confound assessment with pins. How big a concern is this for a bored hole? Something has to have gone very wrong to get significantly out-of-round using a boring bar.

Locking your spindle and test indicating the boring bar would give you a pretty good idea.

[@shawn01707]

.0001” test indicator is my favorite indicator for a reason. You can check soo many things with high precision. Your only limited by your creativity. Even a .0005” indicator is good as u can read between the lines to .00025” pretty easily.

[@davids.682]

There are several comments about different deflections from non-uniform material removal. That is true, but they missed one thing in the process. He bored in and out of the hole. The bore out cycle probably had a very light cut no matter how much material was removed from the bore in cycle (within reason).

[@chip1pan]

Couple of things. First don't forget to notify what direction to have your too facing at M19 so that when the boring bar exits it does not leave an exit mark. Second it is always common practice to do a spring cut before making any adjustments. Other than that floorless. And for the metric guys just times the imperial figures by 25.4

Sigh. This “hole size” “pin fit” test has always been a massive confusion in every shop I’ve been in. “Well if the 1.000” pin goes and the 1.0002 doesn’t ,Then it’s 1.0000 perfect” No If a 1.0000 pin goes, there is space in the bore. How much is unknown , but it is bigger or the pin wouldn’t go in. I would say this is somewhere around 1.00015, to 1.0002. For a 1.0000 perfect hole size , your looking at checking with a .9999-.9998 pin floating in , and a 1.0000 pin as a line fit or a “no go” pin. Yah after 30+ years you learn things … I learned this from an master inspector, when I couldn’t understand why my “pin went” in, but the zeiss CMM is showing it’s oversize by a few microns. He then explained it to me and I was like “ ohhhhh “ right makes sense. A perfect 1.0 hole is not going to accept an perfect 1.0 pin . Bottom line.

[@whispers391]

[@stevel2419]

This is correct. I have made thousands of aerospace parts in my life time. When there is a callout +/-.0005 or less on a bore, I always confirm with the customer what is the method of inspection they use . If we are using gage pins we use the .0002 rule.

[@SFTUBEBENDING]

Wondering what the thought process was when implementing this workholding. Was it done this way to do one part with different intention if they were being manufactured in higher volumes?

Before u bore the hole to size first check to make sure they are concentric to the datum. Then take a rough pass with boring bar , check concentricity again then finish bore it to size. And I like using bore gauges but the pin works too.

Charlie, Circular interpolation is a nice feature. But a boring head is far more accurate. When the hole calls for a .0005 total tolerance, interpolation will not get you there in production. There are too many variables. One great technique is to drill, rough circular interpolate and then boring head to size.

He must have measured it when it was -.0022 because his pins didn't go down that far. The deltronic pins are a good way to double-check that the bore gage is set accurately.

Use a tape measure and call it a day lol jk but perhaps a bore mic or air gage?

I operate this boring machine. But when the machine is in trouble. Like over bored. I'?m the one who adjust the diamond.

[@lokeshweruday]

Is it boring or interesting?

[@Baard2000]

Definately BORING...😁😁😁

[@nonjb3811]

Wrong here: he should step down 0.0002 to be correct. He made 1.0001-1.0002 hole! Meaby he knew, but was afraid to show that 1" pin wont fit , but 0.9998 will fit? Then there will be questions here to answer , whyyyy??? :) (one inch pin will go to 1 inh hole - but only with press device...) He was within 0.0005 tollerances for sure, but could do more precise job! Sorry for my english... (Like for his presentation going anyway)

That is sick.

[@Inventorsquare]

If you got a nickel every time you heard the "boring" pun, what color would your Lamborghini be?

[@hughmcallister2574]

Ream?

[@mikeriechers9187]

Reamers are useless for precision holes they'll make the hole hexagon
