G & M Code - Manually Programming an Invisible Stop - Vlog #46

[@igorberam]

I've been doing this job for too long, I love that Titan makes the videos. People that do our job, we are a different breed. We alive military style and we are perfectionist in everything in life. I respect all of my fellow machinist. People don't understand the pressure and stress we live with.

[@kumo9993]

It definitely is a stressful job sometimes even an apprentice 😂 when we're working with 0.02-0.05mm tolerances (1 or 2 thou) on bearing journals in a part for an expensive assembly, a simple wrong button press or oversight in the setup can cause huge loss of time and money for the company and client. Pretty much everything that my workplace works on is for the mining industry and some of the stuff is insanely big (we have everything from small jobbing lathes to 8 meter diameter vertical borers, 10+ meter floor borers and 14 and 15 meter gear cutters) so a small mistake on some jobs can literally cost millions of dollars. I was the last apprentice to work with this one particular machinist who ran a huge manual floor borer and one of the best pieces of advice he gave me before he retired was "In this kind of work your mind has to be present at all times. Anything at home or outside work, don't think about it. If you're not present then just go home." All that being said it's the best job I ever had, and one of the few that I find fun and interesting enough to make the stress worth it. Finally found an industry where being a perfectionist is a good thing

[@vtcnctech]

Because of your videos, I landed a job at Diamond Tool & Die Inc. in Oakland. I’m going to study, work hard, and implement everything you’ve taught us who want to learn the cutting edge of cnc machining. Thank you for your priceless teachings, literally how do you put a number on the knowledge you teach us? You can not, it is literally priceless brother.

[@NorthViewModelShop]

Dude my mind is blown. Where I work they have a machine shop in house and they boys are really good at what they do. I love hanging around when I’m free and ask questions. I don’t have the mind to do this kinda work as a day to day job, but it’s cool as hell to watch and the logic you guys use is super cool. Keep up the good work

[@whispers391]

We use this method for 90% of our work and absolutely love it. Most runs of parts are from 10-30 which works great and no waiting on a probe cycle.

[@billgreathouse1913]

Yes, this is a nice old trick before probes. I've done this for years and even have had the machine move the part for me. Last hole is done and tool changes to the disappearing stop of proper size. Once the pin is in the hole, hold and loosen the vises and resume. Part feeds over to NE location and hold. Tighten vises and resume. I find it best to use stepped vise jaws as to have no need for parallels. You have to be careful of bowing with really long parts. Like Titan said, you have to put the thought into it and you can solve just about any problem. You don't need no stinking probes....lol

[@chraven69]

Very true. I also used this to reposition a larg round plate. Using a hole i turned the hole plate 180 degrees as it was to large to machine from one side.

[@comictrio]

I used to use the same technique, but I used hardened and ground dowel pins instead. Either way it still works great. I did it because the operators were pretty tough on fixtures, and back then, we didn't have the fantastic fixtures that are available today. Back then we had to create our own fixtures and often times the operators would knock fixture stops pretty hard, especially with large parts.

[@marcusmadrid7508]

Tricks of the trade!!. That’s how you use the WHOLE TABLE. You can face your material with out any worry of a stop ever! Titan. I orient the spindle before you rapid down. It will make your parts repeat even closer. When you gotta hold that true position of .0005 haha

[@NoriDavis]

What I like the MDI on HAAS controls vs fanuc or other controls is that anything that you put in MDI stays there and doesn’t automatically clear out so that you don’t have to re-enter it if it’s something you need for every part. Such a great pro for HAAS machine controls!

[@michaelcoffin4364]

Another trick is to use old end mills as indexing dowels in fixture plates. I do it all the time on my machine.

[@billgreathouse1913]

Yep. I've even put them in a hex, 5c collet block and held that in my Toolmaker vise @~25* and ground flats on every other flat of the hex collet block. Makes it just like a locating pin that's easier to hit the hole with. This way is more expensive than a locator pin but sometimes it beats waiting on ordering them when you need them NOW. Other than saving lives, this has to be the best trade on earth.

[@jeepmanxj]

way too hard. It will typically mar either the part or the fixture. Just use a ground pin.

[@thetruthyouneedtohear]

Excellent. This is how I set the origin on fixture plates that I use. I mill a .250" center hole/origin. Anytime I want to use the fixture, I tram it in, and then drop the pin into the center hole, and boom, origin set.

[@JSAFIXIT]

I have been in the cnc world for a while now, and made a transition to cnc routers because of better hours, location etc (I live in the middle of nowhere). I get the pleasure of training in new operators. One thing I struggle with is trying to get them over their fear of mistakes. It's going to happen, you will screw up. It could be a simple bad part, or you could run a bit into the table and shut the machine down for a week. When it happens, we will use it to learn more. This fear however limits them. I understand the machine and tooling and especially the attachment we use to add another axis that allows 3d parts is not cheap, but you can't let it stop you.

[@swikocki]

Nice tip for reusing the broken Endmills, always used hardened pins before. Got to be many other uses for used carbide other than only scrap value.

[@Mark-km4gp]

More types of these videos please. Was actually doing the same concept trick but on a lathe a guy I work with taught me. Had to rough these tool steel shafts and didn't have a stop on the jaws but the stock fit inside the spindle. Chuck on the material (make sure it's only sticking out an inch or so) and have a cut off boring bar as a stop that the machine would rapid to so you can pull the part out to the same spot every time. Boom!

[@helicopterjohns]

Hi, Good Tip. Thanks for sharing. I have some 1" wide extruded rails that I machine key hole slots in on my 2007 HAAS TM-1P. that are about 70 inches long. During the machining process I have to open both side windows. As the table only has 30 inches of travel I had to make a couple of work offsets to do the job. I also had to put some small tubs on the outside of the window frames on the floor to catch the coolant that ran out the ends of the extrusion during the machining process. I have both a PCOOL system and a manual coolant nozzle with an associated cut off valves. As all of the machining was done at the same level I used the manual coolant nozzle that fed from the front of the spindle which pretty much contained the coolant within the enclosure. If I used the PCOOL nozzle that fed from the right side of the spindle it would shoot coolant out the open left side window of the machine during the machining process. Kind of a (clean up on aisle 6 type of thing) Ha Ha John

[@TITANSofCNC]

That’s Awesome!

[@jimfran2761]

Yea I love this trick. I use an extra work location g54.1p8 on a sharp mill to keep a work location for repeat jobs then in the main program I use the basic g54 and g55s.

[@designbydave]

Dude, Tyson. I was literally machining a 51 inch mold in a machine with 30 inches of travel last weekend that I needed to shift, just a smaller version of the Boeing part you described. Holy piss how did I not watch this video before doing that. Thanks so much for sharing your knowledge with the world!

[@TITANSofCNC]

Awesome!!

[@TITANSofCNC]

Glad you enjoy it!

[@radoslawjocz2976]

I used it quite a lot in the past. This method is often used when you need to flip over the part held in chuck and locate on the hole from previous operation.

[@dennisoakes3227]

That's a great idea, thanks titan! I use a similar trick on one of our lathes for partoff jobs, I put a 1 inch machined bar in one of the turret tool holders and bring it down to a location, then u pull the stock out till it hits the barstop. Way better than a hand stop

[@colinbagshaw1796]

IUse the flat side of the part off toolholder

[@kalblades]

This is great! We need more videos like this! Thank you Titan! ! ! !

[@TITANSofCNC]

Glad you enjoyed it Kyle

[@maquinadosrascon]

Just one thing: Be careful with the cycle times. A colleague of mine used this method frequently to do his setups quickly which was fine for short runs. But then he was using it unnecesarily for long production runs wasting hours of accumulated cycle time because he was lazy to expend 5 or 10 minutes setting up a physical stop and edge finding the X value for UCS (G54, etc). Another thing that happened once a while was the operator putting the part before running the stop, crashing the machine (I assume this also happens in Titan's shop, thats why he moved rapid to Z0.1 then feed to Z-1.0 instead of just rapid to the final Z stop position. Still a F100. can do some damage.)

[@A-a-ron80]

Great tip Titan. Same principal used for a bar stop on a bar feed lathe.

[@85CEKR]

Ya as soon as I realized what he was doing I had the same thought.

[@stevec1586]

Used this technique many times. If I'm cutting all 4 sides of the material I'll use an adjustable machinist square and scale off of my hard jaw. I've also used this pin method for 2 part programs when a part is longer than your travel. Boom!

[@martl.4650]

One tip I would add to this tip is tight the collet by hand not with a tool so if your operator put the stock too far, the endmill will retract in the holder instead of 'crashing'

[@stupidsmart101]

Wow never thought about that good stuff man 👌

[@raymondvanroest372]

Hey Titan this is a simple and effective time saver I have been doing it like this for years now. The company I work for know the guys are so set in their ways, that they cant see the advantage of this method. So I took 1 of their simple jobs that's held in a vice, they have a stop on the table then place a block packer against that then load the part in the vice then remove the block packer and machine the part on both ends and drill and counter sink 4 holes in it, time consuming if you ask me. I set the job up with the stop pin method you talk about here. it drops in place BOOM, load the part and press cycle start, never worrying if I have removed the block packer. save about a minute a part finish the job in a few hours all to spec and in half the time. this is in a small old Leadwell vmc25. They complain still oh I have to lean in to far to do that or the spindle is in the way not realizing that the job takes half the time that it used to do. then I want to fixture the job as a set of parts but they dont want to spend the money on it because we have been doing it like this for decades.

[@tonybolakowski6076]

You have a great attitude brother.

[@1AMERICANWORKER]

My experience is limited with automated machine tools. I was a Westinghouse apprentice in the early 1970s, trained as a Swiss-style toolmaker. When I did go to work at an automated shop, the jobs were run on mylar tape ( Bridgeport Boss 5 ). One of the first programs I wrote was for a part that required two hold/stops to move clamps. These machines were also manual tool change and required a hold/stop for tool changes. Every operator we put on this job would eventually have a brain fart and do a tool change with the clamp move, driving a 1/2" long flute endmill into the vise. I solved this problem by blocking in the shell mill that was in use when the clamp change hold/stops came up. The hold/stop was re-programmed with the shell mill 1/2" above the dead jaw. That way the tool can't be removed. Just something that some programmers can overlook. This can save a lot of drama, especially if your shop uses entry-level operators.

[@mcnultyfp]

Very helpful. Thanks for this and all the generous instruction. When my cnc table stops skipping steps and making disastrous mislocations, won't it be nice? Having the whole thing rebuilt with encoders or servos. I'm about $20,000 invested and one year of head scratching with no productive capacity, but that's only bad choices of equipment, and the head scratching making more dandruff than synapses.

[@76Rooroo]

I do this a lot as well on a HBM when I run a production job. It’s a great trick man.

[@akronimm862]

I haven't used pin stops for a lot of things while trying to machine parts, but when you need them and when you can use them DAMN do they come in handy

[@matthewbehrens7091]

These days you can incorporate touch probe cycles within your main program that will update your coordinate system. But you use what you have.

[@TITANSofCNC]

Definitely

[@danthoreson4062]

I love these videos. I wish I knew where there was some millwork in my area. I'm working swiss right now and the learning curve is STEEEEEEEP

[@demandred1957]

But you can do x and z as well..Find a holder with a wide face, do a tool offset probe on the HOLDER, insert the pin and now, you can use the face of the holder to set z on a "floating" part and the pin sets x. I do this all the time on a few small odd shaped parts, where I have sq sides, but nothing on the bottom to set on parallels.

[@OGbqze]

I've ran into 2 part stops so far and I'm sure I'll run into more. Luckily it's always with an insertable rougher so I just change the inserts instead of ruining an expensive endmill.

[@boost219]

We had stops that mounted to the back of the vise at my old shop and one time the z didn't clear the stop and yanked it out of the vise and shot the bolts out when x went home at the end of the program haha.

[@jetsoswd9393]

You're the man. Have you done video's on how to learn more about sub-programs?

[@mirzoni5331]

I know this trick i used this before. Thats nice. Sometimes when i have broke 3d taster for offsets i use this trick for measuring x y z offsets. Nice man nice.

[@bethanypilant5732]

I like this trick. Useful for work that needs the ends cleaned up when the hard stop would get in the way.

[@Dutchamp]

The trick with longer material into your vices, I did this trick on conventional machines too, at least it had a digital axes counter. 😜 I'm 55 years old now been milling sinds I was 16 years old, never had cnc machining at school. Also later on not one employer had an idea to let me learn cnc. So I explained to the welfare here in my country, told them that it was cheaper to let me learn cnc wile I have no job, wile I'm benefiting from the community. So they saw the light and gave me a chance to learn cnc. Now I went for iso cnc, still on school. Learning heidenhain. And have fun again. About two weeks I get the diploma and then employers want to have a skilled conventional engineer who can program aswel. May 13 years from now I'm done working or having my own company

[@gerardkrige875]

I had to repair a 100 components a few years back. The angle was important, so I actually made a “L” stop to fix into my fourth axis. That meant I could actually program at which angle my part would rest.

[@gianpierovito4789]

Old school method, used for years. It's great especially for large parts, water jet cutted parts, tiltened vise on a 3 axis machine, when positioning is difficult. But if u works on small parts exceeding for a few amount the jaw, for example imagine multiparts on a tombstone, it's mutch faster to produce a little '' L'' caliper of the exceeding misure u need also in alu material and use it to clamp the part. Use this trick save u wasting time by launching this program to clamp 40 parts on a tombstone.

[@tmr626]

Titan, have you ever machined any 3D custom billet aluminum one piece wheels from a solid block, or just the two or three piece wheel centers? It would be great if you showed the whole programming and machining process up to the finish. Take care!

[@machinist7230]

Ive always heard it called a pin stop. We keep one peramently set up for when its the easiest solution.

[@horseshoe_nc]

I sometimes do similar just with a dowel pin. Prevents a crash into traditional a removable stop.

[@TITANSofCNC]

Awesome

[@johnl5177]

I first used the Boeing trick you talked about to run a flange plate around 45 inches bolt hole patern in diameter on a haas vf8 about 5 years ago. The machine only has 40 inches y travel. Had to talk with the boss to (cover my butt) that I could run it with the front doors open ran first half of the holes then spun the plate around 180 to get the others. Useing the drill bit to locate two holes from there I could use clamps to clamp the plate down. It was a pain to locate

[@ExMachinaEngineering]

Yes!!!! Yes!!!! Thank you!!!!

[@TITANSofCNC]

Glad you enjoyed it!!!

[@neilhuband995]

Or you could just mount a removable stop to the fixed jaw of the vise. Remove when not required. Or you could just locate that part to the edge of the fixed jaw of the vise. Both those options would save you from wasting tool carousel (if we're taking Haas mill) space in the machine. On CNC lathes, when I've ran a part, I would use the side of the turret as a bar stop. All you do is open the chuck, pull the bar out until it touches the turret, then close the chuck and you're ready to machine another part. You can actually buy a bar stop which uses the space for a tool??!! Why the hell would you wanna waste tool carrying space for that?? lol

[@VulcanBomberxm655]

We have bar stops on our lathes at work, but we can open the collets when the spindle is running. Stops them sticking so much.

Neither of the things you mentioned are always an option and neither are as accurate as the method in the video.

[@neilhuband995]

@@danieleiferd4978 A hard stop on the vice is accurate to tenths, provided you use it properly, and clean it down with compressed air before locating a new part. It's a hard stop! Of course it's accurate! Nothing should be moving. If something is moving, then you got bigger problems lol Edit: and using the side of the turret as a stop is perfect too, because the first operation you're about to do is rough face 20 thou or whatever amount from it anyway, so it makes zero difference if it's 5 or 10 thou out. (Which is very unlikely anyway)

[@danieleiferd4978]

@@neilhuband995 The entire point of the pin stop is when you CAN'T use a hard stop. When you said a "removable vice stop" I thought you meant a spacer or something against something else in the machine that you remove each time. Of course a proper hard stop is best but it's not always an option.

[@TheAefril]

Hi Titan, I am not a machinist. But I love your videos for the insight they demonstrate in rebuilding a creative industry. I hope this does n't sound like a stupid question. - All the dimension or the coordinate data you are numerically programming into this machine, - are they all fractions of an inch (is it Thousandths of an Inch)? It is a little confusing for me, as we work with Millimeters in Australia. Love the videos, keep them coming.

[@chiefmachining7972]

Used to do all the time with bigger parts only thing I do different is move off the part in x before Rapiding off the stock

[@sleddarcheddar]

I can see this being useful for 2nd op or later ops. For 1st op with rough stock wouldn't it be easier to just use a stop-loc adjustable? That's what I do when a stop will interfere with op1

[@sleddarcheddar]

Also to add I've been using this method for a while. Just never for op1. It's a great way to ensure your part is where it needs to be in relation to where the machine knows where it is. 😀

With rough stock like he has here I've scaled to the jaw, very fast no problems. Nowadays it seems operators are afraid of scales 😂 but if I program this pin stop method they're ok with that.

[@chraven69]

Nice. You can call other programs and run them from your current program, then return back to your program when its finished. The method is using that program as a start what you can do is save it as a pinstop program say 123456 pin stop. Then from your man program say its called 123444 wing hinge call up your 123456 pin stop program. If you do this you will need to call up your main program from within your pin stop program. This tip will save you time in loading each program manually.
