Acrylic

Post by ReneeL1980 »

Hello

I have just started trialing some cuts out of acrylic (fine ish text) and I am finding some of my letters looks a bit wobbly, rather than a perfect straight, Im thinking it may be the speed I am cutting? Could it be my bit? I am currntly using a 2mm Up Cut End Mill.
Any tips on "tabs" for plastic, it is so time consuming filing those bad boys and as I am using small text I need a few to avoid snapping my material. All tips and tricks welcome!!

Thanks

Hi Renee

Along with what Michael said above you may want to research the tape and glue hold down method so you won't need tabs and also what type of acrylic? cast cuts better than extruded for me it also must be flat especially for small letters

Thankyou!!

I slowed the speed down and it helped alot! as a result I dont need such heavier tabs!

Will give the double sided tape a go!

Thanks heaps

You should try an "O" flute bit. They are designed for acrylics and plastics. That may make the lettering cuts cleaner.

I have an Axiom AR6 Pro and cut a lot of Cast Acrylic, I use an amana 51411 0 flute bit using the published speed and feeds.... never had a problem over the last several years using this bit... I do use a conservative depth of cut as time is not a cost for me.
With my recent purchase of an 80Watt laser all my cutting is now done on the laser except pockets which I still use my cnc.
