An advice on the cut speed and router bits for starters/beginners.

Postby Goose » Fri Apr 17, 2015 5:21 pm

Hi AmateurCNC Community
We(I and a couple of friends) built a DIY CNC plasma cutting table some few months ago. Today, I have just bought a small router which I have successfully bolted to the plasma cutting table. This is where trouble sets in; I have no idea whether this router is powerful enough and whether I have the right cutting bit. I also have no clue on what feed speeds to employ.
I hope to get suggestions from this forum to get me started.

Hi OP
Can you give us some more information about your machine so as to make it easy for us to solve your question? Thanks. :!: :!:

Sorry, sorry sorry - My goose is cooked!

Sorry for omitting useful information. First the router has variable speed; 11,500 to 32,000 rpm, 650W with 6.35mm (¼ inch) and 8mm collet. My plasma cutting table is powered by dual slaved steppers one on either side. The X side has 1200 oz steppers while the Y side has 270 0z steppers. I want to cut MDF and light pine timber. Is my machine powerful enough to perform this work?

I think your machine powerful enough to cut wood. If you have been following this forum keenly, you will notice that there are individual using 127 oz steppers on each side to route. I think it all depends on the federate.

I humbly urge that you start making straight cuts right away as a simple test program while at the same time varying speed and cuts. While cutting, compare the cuts of cuts and listen to how well the machine cuts. This is a simple trial and if you are keen enough, you will identify some of the errors during cutting.

Thanks for the strong advises. So how low should my speed be? :D :)

You can start slowly at 200mm/min f.x then move on from there. I also started this way and it worked. The test helped me to learn faster and avoid a lot of mistakes. Good luck in your test.

I think I am understanding you… I have tried that before, I don't know if there is something I am not doing right. I have noticed that the router bit that we bought is a Tungsten carbide tipped straight cut 10mm with a width of ¼ inch shank. Will this be able to plunge into a though timber or will I be required to start from the edge?

Hey, OP I wonder why you are so worried. Your machine is powerful and it withstands harsh conditions. I know of friends who use a 1/8inch (3.175mm), while some uses 3/16inch (4.762mm) and others ¼ inch (6.350mm), 2 flute, up cut bit or spiral and they do some incredible work with it.
