Tips: Youtube about chip thickness

Admin, please move if this can be considered wrongly posted.

Is average chip thickness an outdated concept? | Seco Tools

A bit long but I found the clip interesting.

Slightly related I currently try to figure out paths for cutting with constant tool engagement angles in inner corners in the attached file. They mention this case in the video.

Think I got it right then cutting against curved surface inside or outside which is a start and maybe also got the equations for gradient correct but still not integrated to curves. Seems to work well for helical enlarging a hole on inside, made a small Octave program to make such an operation.

Have only spent a few days on it but plan is to calculate paths so that tool engagement angle does not get larger in inner corners and make program to calculate path to cut a pocket with constant tool engagement angle. And of course in the end add it to FreeCAD.

I have quickly looked through your PDF and there are some Swedish paragraphs left in the document.
Page 4: "Länkt till beräkning skärningspunkter cirkel." and "Villkor lösning existerar plus mer."

Page 7: "Vinkeln där nere ' är känd medan den där uppe är skärningenspunkten mellan verktygets periferi
och materialet som bearbetas. ' är vinkeln verktyget rör sig. För varje position ska det gå att
ställa upp en ekvation för vilket håll bearbetningen ska ske för att få önskat eller så stort en som
möjligt och startpositionen är känd."


Page 8: "För varje verktygsposition i (x; y) planet ska ekvationen för vinkeln ställas upp."

Nice idea :idea:

Hej, har du texten på Svenska som verkar var ditt original språk i dokumentet?

Nej men har jobbat lite mer på dokumentet.

Have written a little bit more on the attached document.

Well, okay.
I look forward to the next revision, because I still see Swedish text on page 4.

Think there is no Swedish characters left now. It is still work in progress marked with things I now is missing though equations for more general case seems to work for simplest case then doing a numerical experiment. Should not be to hard to add the other cases but do not know which day I have time.
