Title: Bevel Gear with LazyCAM!-2
Post by: adprinter on January 18, 2011, 02:13:54 PM

I tried to attach the uncompressed G-Code file to my first post. However the file size exceeded the limitations, so I compressed the file into the BevelGear.Zip file, and tried again to post. I received the message "You have already posted this file", but since the attached file did not upload (due to the size limit), I had tried again to post. Please see the attached BevelGear.Zip file for the G-code file BevelGear.tap

Here is a poor pic of the gear cut out.

I guess I should have mentioned, that I have my 1/8" ball nose end mill set to 0.1" depth of cut per pass in LazyCAM. It doesn't make for a very pretty picture, when viewing the toolpath. But it does cut it without breaking the bit. If you want to see a toolpath which sketches the finished part, you'd have to set the depth per pass to the full depth of the part (about 1.5" per pass). Unfortunately this would result in a broken bit, as it plunged full-depth instead of actually cutting the part. I also did another bevel gear as a spiral bevel gear. Using the same tedious trigonometry to determine cut depth for each profile.

Mike,
If your into gear making suggest you have a look at this site. Art wrote a program to do gears and it is slick.
Will save you a lot time.

Art is still working, like a beaver, on the bevel gears but he will not stop until it is done.  ;D
Best $75 I ever spent.
