Which is the best router blade to produce a rough cut surface?
I'm looking to use a CNC router table to flycut the top surface of some wood. Importantly, I need the surface to end up quite rough e.g the type of rough cut surface you would get from cutting some wood using a circular saw (but without any machining marks). Which router blade should I use to achieve this? Or is it more a case of reducing the router cutting speed. Whenever I have used a router to cut wood, the cut surfaces have been left quite smooth.
The cut top surface of the wood needs to have no machining marks. This is the main reason why I'm considering using a router. When I have cut wood using a circular saw, I really like the slightly rough texture and look but unfortunately you also get faint machining marks which I don't want.
I have tried planing but it leaves the wood too smooth.
I think you have set yourself an impossible task. Unless the CNC router is your own, I can't imagine any company willingly using inferior grade tooling in their machine to try and produce a surface finish akin to a circular saw without the saw marks. I can think of only two ways you might achieve such a finish.
Firstly try to buy the wood direct from a lumber yard. Wood that has been planed on both sides and then returned to storage would have a raised grain when sold. Alder would be a perfect example of this.
Secondly you might try re-sawing it on a bandsaw, with a wide blade and the correct feed speed you might achieve a rough finish with out the tool marks.
Having seen a number of your questions on this or related subjects I am intrigued to know just exactly what it is you are trying to make.
