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!

[CyberscoutX]

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

[Truckers]

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!

[AndJusticeForAll...]

Dang bro, Titan changed your life, sent you around the world seeing all kinds of cool stuff. But you absolutely earned it with your knowledge in Swiss machining. Im really happy for you friend. Much Love from Dallas TX.

[markdavis]

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

[halfhappy]

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.

[deanavitale]

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

[tj]

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.

[curiouskarl]

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

[abelmartinez]

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

[randywl]

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.
👍👍👍

[Kurtaurus]

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

[piratiniwood]

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 😵

[luisontiveros]

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 ....

[coachingwinner]

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?

[drafty]

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.

[AB-pboo]

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!

[AmateurPlaysGames-ouon]

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

[Sara-TOC]

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.
