When you talking speed is it how many RPM's your tool is spinning or how
fast your table is moving?
How deep are you cutting? Some plastics will melt in stead of cut.

Subject: [CAD_CAM_EDM_DRO] Very Confused!! Need help.

I recently finished my first homebuilt router pouter project, and was
doing some trial runs for a while now, just figuring out the best
software solution etc. etc. So basically I've been cutting air for 2
months now just to suss things out..

One thing I now realized that I made a mistake on is my ever increasing
need for speed, so at the moment I got a good mix between speed and
torque.

Now I started putting some wood and plastic under that cutter to see the
chips fly, and lo and behold all that speed was completely unnecessary,
I'm not able to cut anything at speeds more than approx. 5mm per minute,
what am I doing wrong??? I keep breaking bits if I go faster, or the
cuts become very dirty and especially plastics start chipping etc. So
why do I keep reading on these forums about xxxx ipm if all that speed
is wasted on everything except G00 rapids??

Maybe one of the boffins on here have some idea of what I'm talking
about, and maybe able to help me understand this...

Any help will much appreciated.

BTW. To all the lurkers out like me out there, it really isn't that
complicated to make a machine so start already.....!!!! You'll be amazed
at the feeling you get inside the first time that machine starts moving
on it's own..

Thanks
