   beech is common material. you can take milling machine and will done with it.)))

   Note - I've no personal experience with any of these but have gained a lot of vicarious knowledge by watching many of these machines at work:

   It will depend on what you want to achieve.
   A milling machine will cut wood, but it's massive overkill and usually very limited in scale.
   A CNC router will do the job best for larger pieces.
   20mm is very thick for laser cutting but of course it can be done with a lot of burning - if you need a lot of fine detail that might be the way to go.

   Okay. Thanks for your advice.

   I'll bet a water jet could do it.

   We are a bit in the dark because we don't know why and what you are cutting out of 20 mm beech.

   Cutting 20 mm wood with a hobbiest grade laser is of course possible but generally requires a relatively high power (80-100 watt) and air assist. Hardwood generally cuts better at thickness than products like MDF that are mostly glue. My 45 watt machine cuts 1/4 inch material just fine at full power but won't cut 20 mm hardwood. Even with a high powered machine you will likely have some significant burning on the edges which may be an issue depending on your application. If all your detailed edges need to be cleaned up from char this may not be practical. You may also need a different lens to cut material that thick due to the narrow focal plane. The advantage of course is the next to invisible kerf and high precision (and perhaps speed).

   A CNC router is the way to go for most applications cutting out 1/2 inch material provided you don't need sub mm precision. Vacuum can also be helpful if your material is not dead flat after milling. You can certainly use bits down to 1/16" in diameter for fine details although you may break more bits this way. Advantages are speed, almost complete automation and very easy to make replicates.

   A Shaper origin can cut 20 mm beech and can use bits much smaller than 1/16" in some cases for engraving, etc. Downside is that its a manual process and can be tedious if you are doing complex projects in multiples. Upside is you are less likely to break small bits when you are moving the machine yourself and not dependent on predicting feed rates in advance.

   I guess a true milling machine would have by far the tightest tolerances but your parts would have to be small and milling machines are expensive and have a significant learning curve. I think about them mostly for subtractive machining of 3D objects and less ofr processing sheet style goods like 1/2 inch material.

   Not sure about waterjet. Certainly a waterject can cut 20 mm beech but do you want to saturate your material with water in the process?

   You're right. Sry, I wrote so little information. But your advice helps me, thnks.
