Thank you, Stefan! This is excellent information for us old guys for whom CNC is never really going to be an option. Thanks for teaching an old dog some new tricks!
How awesome is that ! I don't have cnc, and my (very) little swiss mill is hard work to setup a rotary table on. You just showed me how to not have to worry about that! And on the lathe as well - fabulous! No need for a sketchy radiusing tool either.
Saw the etch-a-sketch and thought this will be a CNC conversion of one like This old Tony did. Sad it wasn't but also happy to learn so much from this video.
Thanks Stefan. I have neither a DRO or a ball turning attachment for my lathe. I have used a spread sheet to generate X & Y coordinates to turn ball end features. If I ever need to do that again you have inspired me to adjust my spread sheet to generate progressive tool movements and to experiment with tools that have larger nose radius. CHEERS
Fascinating stuff. I’d forgotten the emery cloth + file technique I must have been taught in school nearly 50yrs ago. One extra reason to fit DRO’s to my mill and lathe as well
No not at all, its always good to know the basics. You give so much fantastic information in all your work that is a real Inspiration to stand again night after night in the shop on some own ideas!!
Sometimes you have to remember the old skills to take advantage of the new ones you can have the most advanced cnc machine, but if the person behind it doesn't have the ability to use it, you won't get anywhere either
I was just now testing a program on a 13-axis multitasker while listening to this video. Keeps your feet on the ground and you know that if you crash the machine you can always go back to filing and manual cnc'ing untill the machine is repaired.
Fun thing, that microprocessor inside that DRO most likely has more brains than the average CNC from the 1980s, that did corner radius with no problems
I used to have a little pocket book from my father. It gave X and Y movements with given endmills to create given outside radiu. Move X .01, move y .001, etc. sucks it fell apart years ago.
Awesome video! Clear as mud to me, then again I am not and never will be a maths wizard. You explained the processes quite well, made it easy for this old schooler to understand. It’s possible that I may give the radius approach a try because I am working on a model engine that has a few parts that have radius and I have avoided machining those parts because I don’t have a rotary table. I am not a trained machinists but I am learning as I go…failing forward to successful completion. Good thing I have a lot of scrap to work with.
Very cool idea and extremely well explained (as always)!!! Really cool would be an seperate input (like a foot-pedal or something similar) for the DRO in order to skip to the next step. Then you could leave both hands on the hand wheels...
Bietet es sich nicht an beim Drehen die Digitalanzeige auf Fräsen umzustellen, um dann einfach die Radiusfunktion wie anfangs beschrieben nutzen zu können? Oder hab ich da jetzt einen Gedankenfehler? :p
A really great and informative video! 👍Thank you for it! ❤ However, you should think about a better way of attaching your workpiece (paper)! If the cutter has dried out, these new fancy “Etch A Sketch” machines can cause high tension forces! 🤣 Ein echt tolles und informatives Video! 👍Danke dafür! ❤ Du solltest allerdings über eine bessere Befestigung von deinem Werkstück (Papier) nachdenken! Wenn der Fräser ausgetrocknet ist, dann können bei diesen neuen fancy "Etch A Sketch" Maschinen hohe Zugkräfte auftreten! 🤣
I've seen someone use a cellphone camera. Cellphone mounted so it moves with tool (part) with the camera looking at drawing, then the tool is moved around doing the cutting while keeping a crosshair on the screen following the desired line on the drawing
