Love the charisma!
Keep on making em
I have almost 2 years programming some 3d surfacing and never understood why my finishes never were as good as I wanted, I knew something was wrong with my feeds and speeds. Thanks a lot for the great knowledge shared here!!!!!!! This what I was looking for!!!!!!
Thanks for watching! Ctc
Another great video!
What an episode!!
Thanks a lot don!!
U made it simple.. Taken the help of Lead angle of face mill to explain the chip thinning with Ballnose end mill.. Really that is the easiest way to understand..
Very informative..
Great knowledge, Editing, music and the humor... Thanks for every thing don...
Appreciate your support.. Like to keep it as simple as possible.. Stay tuned for the wrap up before we jump into Circle Segments!!! Spoiler.. Ctc
Thanks for an excellent explanation of the "Your four flute ball end mill is really a two-flute at shallow DOCs"! Very informative and clear. Just one hopefully constructive comment, (please feel free to ignore my advice). The "meat" of the video doesn't start until 3 minutes 52, I very nearly clicked away about five times during that hugely long intro. Asking me to like and subscribe before delivering anything of value is also a major turn-off, and the extended repeat of what was covered in the long outro also had me very close to clicking away. If you chopped the intro and most of the outro, and did the call to action right after the big reveal about 5-axis milling, like "If you've found this useful, please like and subscribe if you think I've earned it", I would have watched the entire thing and clicked all the right buttons immediately. Absolutely excellent descriptive content, definitely 10/10 for the "meat in the sandwich".
I find that very constructive and put very professionally.. I am really trying to make it about the content. Thanks for the input. Ctc
Do toolmakers publish what that distance is axially before all the flutes of a ballnose endmill begin engaging the work? If not, is there a rule of thumb for it?
That is a great question. I would tell you that based on a variety of designs with the gash all manufactures do it slightly different. You could look at a rule of thumb as 3% of the diameter for our steel tools. Now we do make our Aluminum 3 flute balls with all three to center just for that reason.😊. Ctc
Could you teach me about the rake angle for cutting HARD MOULD, SKD61 55 hrc up? I use helix 30' rake -2 -7 +10. Why is +10 the best one.Theory said minus good for hard metal
Lower is better for harder material, But not as low as you would think. I like around 5 Degrees for 55 and up. You still need to form a chip and therefore plowing is not always the best way.. ctc
For the Don's Combat rule of Chip thinning...
