I've machined quite a lot of micro parts on a Taig with a 1mm [.0394in] endmill and I've only ever broken 1, and it was typical user error during tool height setting. Great video!
Very encouraging work and guidance, thank you. I have a 24k spindle but am also finding it useful down to 4k with appropriate feed rates for drilling (for now). Milling is yet to come :-)
Hello, thanks for the video. A point to consider is the acceleration of the motors. If the piece to be worked is small, there is no chance of developing all the feed rate. If this occurs, high rpm in the spindle is useless, they end up wearing down the tool due to friction.
Nice video! I enjoyed having the CAM with the actual machining in the corner. I would like to see how you set the tool heights, especially the tiny end mills!
Thanks. I showed how I set the tool lengths in my previous video. I use an Edge Technology Touch Off Gage just like for any other end mill: www.edgetechnologyproducts.com/touch-off-gage-52-000/
Speeds and feeds are the one topic that can catch anyone, too many variables but you ignore them at your peril. Love to know how you set the tool offset for the V-bit and might a ball nose have been a better option?
I just use a Edge Technology height setter like I do for any other tool. The V-bit is pretty strong, so I'm not worried. I prefer the v-bit over a ball nose end mill because it has a flat tip. The ball nose will have zero cutting velocity at the center. Whereas the v-bit is more like any other flat end mill.
Just found out how much they stripped out of the personal use Fusion 360 yesterday. I'm setting up a new to me mill and can't believe I'm either forking over $40 a month to use tool changers/4th axis/rapids or try learning Solidworks as they have a $20/year personal use license for vets.
I do in my latest video: th-cam.com/video/WsUpLqfBhVM/w-d-xo.html. I used GWizard to calculate feeds and speeds and it did not let me down. Everything worked without issues.
Watching your work through problems is exhilarating. Thanks again for putting out your insight

Feeds and speeds?
This is great! Thank you for sharing and teaching your process. I recently got a taig mill and have found your channel to be extremely helpful.
Glad it was helpful!

Yup. It's all about feeds adjusted for your spindle speed.
Great stuff. Always enjoy watching your computer engineering.
Glad you enjoy it!
I love these how to vids, I have learnt so much with your help.. please just keeping Posting :)

@@JohnSL I'll check it out, thanks for replying back!
Another great video John.
As always another good video always learning.
Thanks for sharing! I guess I have molds on the brain. I was expecting to see it in plastic at the end.
Yup, just a test piece this time that has no other value.
Thank you for this.
Hi John, are there any particular types of cutter/coating you use for aluminium? Do you have any cutter brands you recommend?
Super helpful! Thanks!
You're welcome!
Where are you getting your micro mills, especially the tapered ones. Thanks for the great content!
I've been buying my end mills from here: bitsbits.com/

Are you kidding? Why don't you go and spend 13k on mastercam?
so I am 3mins in but would the text not be back to front if you filled that with plastic ?
This just to illustrate micro machining, so it's not an injection mold.
Just curious, could you post a link to the video where you said you would do this on steel? Do you have anything on stainless steel?

yay
I am only for the hot chicks that hang out here.
