Actually if the old lathe is equipped with automatic tool setter stuff, this is not an issue and you can hit these tolerances anyway by measuring the tool from time to time by program. That was around at least in late 1980's in high end machines I believe.

Two tenths tolerance and I'm losing sleep over my mic technique. The quality guy and I will probably argue about something, between the mic calibration and how much pressure we put on the knob. Even with the ratchet type mic handle you can change the reading by at least two tenths. And we have some dirty mics, which I'm sure changes the amount of torque the rachety clicky handle applies.

Excellent video! If your cutting stinko inconnel remember it springs .04mm so..... If you wanted take off .02 you need write down your off set as travis has calculated it and that will sort out the next component 1st time , meanwhile you need to back off the finish tools .02mm to complete the current component. Or if your boss ain't on your back measure the 1st attempt spring pass the test cut dont measure it (hopefully have more than .04 excess material) and then add Travis' off set . With some Aircraft materials you need to appreciate the elasticity of the material and this makes a big difference between sizing in and Booom right 1st time ! Plus the offsets will alter over the course of the day due to spindle and material temp , size in every morning and after break and never trust the night shift 😉😉😉😉

@williamlee7371 2 года назад

The lathe I used had a similar push off. If I was 0.01mm undersize on ID I had to offset away by 0.02mm for my spring cut. But then for the next part I had to put 0.03mm offset back on. Also my advice is to SLOWLY input your offset. Trust me you don't want to accidentally take 0.1mm off when you only wanted 0.01mm but you pressed too quickly to notice.

When setting up for tight tolerances, I programmed equal depths of cut for my roughing passes. I wanted equal tool pressure on each roughing pass. I held a tight tolerance after the roughing passes, which enabled me to take two equal depths of cut with my finishing tool. It was all about working with even tool pressure on each pass.

@isobar5857 2 года назад

One question, if I may. Are the micrometers used calibrated at the machine shop temperature, and the inspection dep't temperature, that is, are they both at the same temperature ? As a retired machinist I ask because I had many arguments with the inspection dep't who would come to check 10ft long shafts, coated with tungsten carbide, which I was grinding with diamond wheels to a tolerance of +/- 0.0002". The problem being, the inspection dep't was temperature controlled, but not the workshop ! And since the ground diameter was in order of 6" it really mattered. Enjoyed the video and just subscribed.

@mxcollin95 2 года назад

Great tip!

@derbacksteinbacker4942 2 года назад

The fun part Beginns if you have multiple tight tolerances in a row that are each fairly long so the part is bending away from the tool ever so slightly with each pass so it gets kind of unpredictable how much it's actually gonna subtract. sometimes get parts with four fits directly behind each other with tolerances as tight as 0,009mm over a length of 100mm and when you got that dialed in you are just happy it's over.

@travisjarrett2355 2 года назад

Indeed. I have battled this myself and have thought about making a video on it actually. It can be a process for sure.

@ytfan3815 2 года назад

@Der Backsteinbäcker I assume you use multiple Wear Offsets for each fit on that part and you change your conical to parallel by program ??

@derbacksteinbacker4942 2 года назад

@YT Fan actually I don't use any wear offsets but a function of the controller . I program the machine to leave 0,05mm radial in the finishing pass. Then I measure the offsets of each of the fits from front to back, compensate for that in the conture until they are within one or two thousands of a millimeter. Then I calculate how far away I am from the desired diameter of each of the fits and bring all of them to for example 0,05mm above the final diameter, also in the conture( In doing this while constantly decreacing the amount of material the finishing pass leaves). When the fits are equal diamter from front to back and equally far from there final diameter I then finish the part without leaving any material. It's a pain in the ass every time and it's probably not the fastest method of doing this but I haven't scraped a single piece and I programmed these 3 times already. another thing that's annoying is you have to run the machine for about 20min or so until it's fully warmed up otherwise you will be working against a expanding machine and a hell of a part at the same time and that's really noting you want to do.

@ytfan3815 2 года назад

@@derbacksteinbacker4942 Ok, I assume you do low number of parts, or single parts. We do lots of shaft work up to 500 mm and I use a 0.5 mm ( in diameter ) leaving for finishing with a DCMT 0.4 rad. We have most of the time 4 fits on one side, and I use T0202 on first fit, T0213 (2nd), T0214 (3rd), T0215 (4th) and so on, when there is some conical in the fit I adjust that by program to get it parallel. I have a Warm-Up program that moves all axis for 10 min with a High Feed, works good for me, after that adjusting Wear Offset when necessary.

Sometimes you have to alter the program to fit the situation.

@GrahamG1986 2 года назад

Theres plenty of things at play here. Are you bar feeding? The whipping in the bar behind the chuck can affect the size, make or use a sleeve to stabalize and shorten the bar length i usually do 1.5/2m in length. How far are you out the chuck? i try to keep it within 2.5D or less if i can so it's parting off as close to the chuck without damaging anything. could drop a tip rad size from 0.4 to 0.2mm that helps alot in some applications, also DOC is important as well, it's not always the best to have the finish tool tickle the material away, or you can be getting deflection if your finishing the part and its got a small wall thickness. Using CSS? try not and just use a constant RPM. I find having it closer to the chuck/collet solves alot of chatter/tolerance issues, Also I've had this debate before about running a cold machine and hitting tight tolerances,

@travisjarrett2355 2 года назад

Hey Michael, while I can't say on the second video I can say that yes I will grab on to those thin walls. I'll cut some soft jaws to make almost complete contact around the part and I'll turn the chuck pressure down to a minimum. May take a few tweaks on some of the parameters but I'm fairly confident we can hold it.

@michaelmacdonough3313 2 года назад

@@travisjarrett2355 Okay. Now I have more questions. Since you're bringing down the chuck pressure and increasing the surface area with the soft jaws, do you look at the coefficient of friction between your soft jaw material and the part, or do you just always use aluminum since it's easy to machine? Will you need to bring down the feeds and speeds on something like this, a second operation? If you do, do you guys have a titans of cnc formula or is it an experience call of how much to bring down those speeds and feeds?

@travisjarrett2355 2 года назад

@@michaelmacdonough3313 I do not look at the coefficient of friction but I like the way you think. I do however lighten my depth of cut and use positive geometry tooling to reduce the pull on the part. Reducing speeds and feeds can help too along with limiting RPM's to a lower max (G97) to reduce any tendency of the jaws pulling out at the reduced pressure. As for a formula we do not have any specific such calculation. We just try to use our experience to machine better than we did yesterday. Day by day.

I've machined things that shape out of plastic and had a lot of deformation and dimension change from having the thin wall at one side. Any advice on reducing warping in that situation?

@simonhygrell4426 2 года назад

lower feeds and speed, inserts that have sharp edges also helps in cutting if you dont have special inserts for plastic it may be much to get inserts specialised for plastic but inserts for aluminum is often quite sharp too, we run mostly stainless in our shop but have aluminum inserts, since we rarely do plastic parts we use aluminum inserts for that

@xflafi8260 2 года назад

Do all the roughing, drilling before finishing, take really light finish passes for minimal tool pressure, use sharp and polished inserts as simon has said On long and thin walled parts it may even be neccecary to finish outer with stock on, then inner, outer again and then inner again If the deflection is still too much, consider stress relieving the Material beforehand, especially on PTFE that stuff can be a bitch sometimes

@travisjarrett2355 2 года назад

As mentioned sharp tools will help. I would try positive turning inserts (walls of the insert taper inwards) as this will create less cutting forces on the part. Also make sure your finish passes are not followed by any large amounts of material removal (no large roughing operations) as this can cause finished surfaces to warp for sure.

@ytfan3815 2 года назад

If possible fill the first hole before clamping on the 2nd operation, put a round piece of material in that first hole that fits perfectly, it clamps together with the thin wall, use an inner ring with almost the same tolerances, you can make thread in it for a puller to pull it out after machining. 😉

@Nathiuz 2 года назад

I've heard a similar approached called a "spring pass". Program two moves at the same "coordinate", one to do the major cutting, and the second pass at the same coordinate to relieve the tool tension, and then dial in a finish pass for the remaining 5 thou or so. What are your thoughts on that sort of approach?

@andersgrundstrom1794 2 года назад

@@Nathiuz It's a great approach for instance in fine turning when the actual cutting time is about ~30 seconds or so, depending on how tight the tolerance is it can be a great way to score within 0.005mm if you're using something like a VBMT 0.4mm, just beware the flexing after like 20-30 parts when you've worn out the coating. Of course if you're using cermet inserts it's easy to compensate for, but for regular tungsten carbide it's a gamble as soon as it starts to differ from the nominal measurements.

Hi Travis, change your Post-processor LOL, I saw your videos on crashing a lathe, but your Tool indexing s_cks. I see Tool changes close to the chuck and then retract your turret in Z 😂, one day you'll hit that chuck with a big U-drill .. 😆 Have a wonderful Christmas 🎄 🎅

@travisjarrett2355 2 года назад

Lol. Yeah it gets close at times. I used to retract all the way home before tool changes but to be honest I've got pretty comfortable with the retract in X only. Saves some time but it does feel like a bit of "faith" at times. Have a great Christmas as well my friend.

@gredangeo 2 года назад

I find it kinda surprising that you're just going balls out on that offset in one pass, for such a tight tolerance. I find that hard to believe. But this does make the video shorter, and give the proper concept. Something that tight should be needing many spring cuts. Because who knows what's really bending more under load. Could be the part or the tool. Sometimes the machine doesn't like you that hour, and says nope.

Instead of M00 and then having to take those out again, use M01. That one can be turned off and on again at will with a button. I always use M01 before every toolchange so the first time a program runs I can check every tool and it's work. Then simply turn off the option stop and let it run.

I think he used the M00 to only stop after the finishing ops. If he used M01, he would have to hit cycle start after each op.

@@pupetxls2 I generally work with machines that are 30 years old, some even older. Most have the M01 option stop, but I haven't really worked with machines from this century.

@clubdjmarcus 2 года назад

@@jonahdement4379 when doing the first run, that wouldn't actually cost much time since the operator is there anyway for initial setup and testing. Also you could have the machine stop after it's current job/tool by the flick of a switch without having to time it. But I guess that's a preference thing. We/I use M00 only when actually needed for things like chip removal or other instructions to the operator while the program is running.

If you are trying to reach people who don't know this procedure where do you put the offset? I know but what if it got put in the wrong offset? What is plus or minus on an ID or OD? Are you like so many other machinists I've worked with absolutely useless when requesting assistance and think not complicated tasks not real high intelligence level tasks you can complete but maybe the next guy needs help not a trap? Or is it you don't know how people learn because you can't place yourself back into not knowing? Wasn't part of getting the job you now have an agreement to want to teach? Didn't you express an interest in wanting to help the trade? If I can help you teach each time you do anything explain the total how and the why please don't just help people just possibly crash machines. So Everytime you touch the control explain exactly what you are doing how you get to that address on the control maybe contrast what the different numbers are what happens if you put a number in the wrong place. Treat teaching as though a person has no clue. That's my opinion.

@Austin17070 Год назад

This is a bad practice and only used by lazy programmers or for one-off parts. For tight tolerances, I always program a "set pass" that is .005" DOC (give or take, depending on the material) offset from the finish dimension. It gives the operator a chance to dial in their tool offsets, which is usually less than half a thou if they set their tools correctly. Once they get it dialed in, they update their tool offset and run the finish pass. This way, the tools in the machine are always set very close to their true cutting size.
