I'm a CNC machinist from switzerland. But in a wood furniture manufacture. I also wrote similar macros for furniture parts and house doors. So we're able to take the measurment at the customers house for example how large and deep the wardrobe has to be. The macro just turns the external dimensions of the furniture in to a program for each part. Like an excel-file with "if-then-function", all the necessary holes and millings were adjusted automaticaly. You remember the tour at the Tornos factory, where every working process is totally streamlined for maximum efficency? In switzerland it is necessary that allmost every manufacter works like this. As well cabinet makers and carpenters. Otherwise the products are too expensive. Love your chanel!

I don’t understand anything about programming but I love to watch everything on this channel , you guys are awesome 🤩 CNC is mesmerizing !

Great video Donnie! You definitely help make macros seem less intimidating. Very practical and helpful information!👏👏

I do exactly this at my shop! We have multiple lengths for shafts on a flange. Using macros we can adjust the part length with 1 number adjusted in the program. Its fantastic.

Always enjoy the funny stuff at the end. Worth waiting for.

Great video Donatello!!! Macro power!

i've been a screw machine programmer for close to a year now and these vids are fantastic, fully agree about writing out every constant in your program even if it makes the code longer (human readability is important), i've already been looking for an excuse to try macro variables and this only makes me want to try it more

I love following this channel. Everyone is so informative, professional, and easy to understand. I am a relatively young machinist rising through the ranks in Canada at just 20 years old. (just finished level 2 of my apprenticeship) I hope to one day... run my own shop Great video Titan & team!

Can you guys do more videos on setting up macros like this? I have seen them before but I always wonder how they were made. Can you do macros like this in CAM software?

I like the way you explane every days stuff like it's something special. I made many of programms like this. In one program I change 13 differences on a part by canging one numer in my program

Hey dude great video, it’s so reassuring when I see someone doing stuff that is so similar to my own approach. I use macros all the time on our regular machines. I bought a book on it years ago and it just makes so much sense to use parametric programming on similar parts. I also like to take a more modular approach, writing sub programs and calling them whenever I want them. It just makes so much sense for the type of work we do.

Excellent way to teach how to use macros , at my last job , i used to have STAR CNC , CITIZEN L20's i had to learn the hard way how to work out with macros and synchronize with sub spindles for shafts over from 3" to 24" using 1 or 2 single programs with macros ....

Hi, I'm spanish machinist programer and I use to use Macros in all machines I code. I did 3d surfaces, coordinate shift and a lot more. Thanks for the video

Thanks a lot Donnie! I hope to watch more videos like this one.

We do something like that in turning parts of different diameters on a lathe (Okuma). We call them "Variable Parameters", but it amounts to the same kind of functionality.

Love the breakdown of the programming... 👍👍

this is very valuable Information thank you

You are an awesome teacher. just the right amount of energy and clear instructions. thank you

Kratje bier 🍻 I think the mathematics genius his name was Marco. Due to a later spelling error, it is Macro 😂 Well done Donnie, writing the whole way of thinking in a Macro is way better.... I had some colleagues who wrote only Macros they even don't understand anymore the next time the parts were ordered 😵

Donnie, Soo nice. Please do more on macros and programming 😃😎

ACB stands for 'Active Chip Breaker.' This breaks chips in a controlled manner, eliminating the accumulation of long, stringy chips, bird nests, etc. It's supposed to save the operator downtime from having to pause or stop the machine cycle in order to clear chip accumulations.

Hey Donnie! I loved the video! You are my fav! Hopefully i can meet you someday and talk about macros! This is so interesting:)!

I do this kinda tabled drawing but i want to implement parts counter with each length variation having different quantities!

Thanks for these videos>>>

So if i'm understanding this right, does a macro in CNC machining allow you to run the same part while only changing one or two parameters?

This is in Dutch and means crate of beer xD Greetings from the Netherlands! I've been watching you almost forever!

Could you guys please put a program for the macro threads epidsode, like you did here? Thanks.

Always hatted those prints with variable sizes on them. Seen many of them years ago for lathe and milling. That macro sure does make it easy though.

Your vibe is so nice hehe

2:22 - months will pass, everyone would forget the details. Then someone would invoke that macro with a wrong value (less than 0.25’), and the machine would crash by moving below zero on Z axis. So - always check user inputs in your code!

This man is the Golden Goose. Well done.

But what if you need to make multiple passes to get to the desired dia? Also would it not read #600 in your macros if you had a value in there?

always wanted to figure this out

Can you please do a video about how to machine Nomex and aluminum honeycomb core?

And again Don Donnie best work!

i love using macro/variables, its much easier in fixing an flawed program when it come to reglage in feed rates spindle speeds and other kind

I’m so excited to finally have a machine that has macros. Back when I worked for other shops on Haas machines, the bosses were always too cheap to buy the macro option. Penny wise, pound foolish.

Never expected to see Dutch in a TITANS of CNC video :o

I machine fabricated weldment and castings . I'd like to see videos on those.Few and far between.

But what if i want the machine to self destruct? What's the # for that?

“Kratje bier” means crate of beer (you did not come close lol) Leuke informatieve video over macros donnie groetjen uit nederland!

Realistically, how many people watching this are swiss machinists?

Love some Macro B programming. It's all fun and games until your material starts shrinking when you turn it, then you just add another variable to adjust for the shrinkage.

Favorite Titan !! +10

OR, write a macro that uses variables. But, use a separate program for each variation of the part which contains only the variable values and a call for the macro. Of course, there is not much advantage to doing it this way on a simple part like the one in this video. However, for more complicated parts with several variables, it saves time by not needing to edit the program variables every time you run a different variation of the part. You just load the program that contains the variables needed for the variation you want to run. It also reduces the opportunity for errors that might happen if you accidentally edited the program with a bad variable.

To follow this better, I typed in: B#600 =11:11 (Video length) () (F: INITIAL FEED RATE =DS.50 This played the entire 11:11 video at 50% DS DS =(Donnie Speed) Much easier for my slow mind to absorb. 😁 I can't begin to comprehend the amount of inputs on a complex part. One single digit entered incorrectly must create scrap metal rather quickly. You guys are doing a fantastic job educating the masses and at the same time entertaining the rest of us. 👍👍👍

I dropped out of college because of programming lol now it's coming back to haunt me

I did a similar program for thread turning 17 yrs ago when I was an apprentice.

perhaps i was taught differently or wrong... but i was told that macros were a sub program called by the main program and using the variables was just that.... using variables...

A simple bolt spacer macro is also good practice for newbies

Hold up, Kratje bier... G E K O L O N I S E E R D

can you make it in milling ???

I love programming with Macros it's a hell of fun to not forget one Makro in a single Line of code. But if it works... hell yes it is satisfying. More on a milling machine than on a lathe since lathe programming is boring.

'Kratje Bier' was kinda close. Means 'case of beer' in Dutch

Please just start using the METRIC or add metric units when editing.

I would rather just run one program and finish all parts on that program and manually switch to the next, why I would wanna do that is because that would probably be faster for me rather than trying to figure all that out and watch it run to prove it out

Donnie lay off the energy drinks man. Those are some pretty jittery lines on that white board.

kratje bier 😅 (beer case) sure would be an awsome machinist

I know a shop that runs macros almost exclusively for production

Do you guys speed up Donnie in post or does he just talk that fast?

It's pronounced Bare Crotch. LOL They got you!

LoL "Kratje Bier" means "crate of beer" in Dutch ;)

Kratje bier means in Dutch a case of beer

kratje bier is dutch for a crate of beer

micro, macro, it's all the same to me'o

Did I just see a knife hand?

Everyday work. Nothing special about it at all.

I think this guy confuses macros with variables. As in , anything unfamiliar is a macro?

Donnie well explained & you have landed @ G28. Titan what a Team you have, Harold was his name Don
