Which is the best router blade to produce a rough cut surface?

Antony G asked:


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.

CNC router cutting MDF?

Antony G asked:


I need to find a way of cutting a sheet of MDF which the dimensions 2500mm x 1250mm x 30mm, into strips 12mm wide.

The cut surfaces must be totally free from tool marks and the strips of MDF must be cut completely straight with 90 degree edges. I’ve obviously considered using a cicular saw but that would leave some saw marks on the material (importantly, it would not be possible to sand the MDF after cutting).

Is it possible to do this with a cnc router/engraving machine? Obviously I would lose a fair amount of material due to the cutting width of the router bit, but as the MDF is quite cheap I don’t mind this.
