Firstly.. the flash may be my fault... I got it as well on a coupel of mine and Im still trying to figure out why...
Some of mine have no flash, some have it.. Ill look again at the final depth calculati
Second.. Colar Ratio is the amount of bar flattened above the involute section. It seemed to me that Id want a bit of clearance bar above the tooth,
so a colar ratio of 1.0 woudl mean 5 mm's of flat bar above a 5mm involute section. Acollar ratio of 2.0 woudl be 10mm's..ect..
Thickness is soemthing I was wondering about, and your right, too thin and its too weak, too thick and it would overcut.. And since the shape
varies Ive yet to think up a equation for that.. the default of 25% seems to work on all examples Ive tried.. so I left it there till I see enough examples
to give me a hint as to how to deal with that one. ( As I said, there doesnt seem to be any literatur
e on this methodolo
ns are welcome.
As to the "thumbnail" , do you mean at the tip the bar seems to be thinner? IF so, thats a bar that beding under cutting stress, beacuse if you look to the
Gcode, youll find its all on a plane, so it cant cut other than flat for any reason other than bending..
I dont think....
I REALLY appreciat
e the photo, it helps to see what you get vs what I get from softer material. Ill do some work on the flashign problem, funny thing is I
calculate the final depth properly and add 10% for safety..s
o Im messing up somewhere
.. or, bending is more of an issue than I thought.. I notice the flashing seems non existant at the base, and grows towards the thumbnail effect.. SO Im thinking its related. I wonder if the depth per pass has an effect there. You might try lowering the depth per pass to see if it rectifies
.. Ill try it here as well.. Now that I think about it, the flash is worst when I do a 1.5mm per pass as opposed to my .5mm per pass runs.. ( Different for all materials obviously
Again, thanks for the photo and the test, Ill make changes for a new release to rectify it as much as I can. If anyone has suggestio
ns on bar thinkness Id love to hear them. TO me, the thickness shoudl probably be a function of the smallest diamter section.. Perhaps we shoudl be cuttong not a flat bar, but a bar that thins as the section narrows.
