In machining steel or aluminum, is the tolerance different for a ream and a drill? An engineering geometric drawing for a machined part with a hole in it has no tolerance on the actual hole size, let's use the hole size as 0.500, but the tolerance block on the print states that a 3-place decimal has the tolerance of ±0.010. If the hole is drilled or if the hole is reamed, is the tolerance the same or is the tolerance different for a drilled hole as opposed to a reamed hole and if so, what is the tolerance on the reamed hole?

Does a beam saw leave any machining marks on material? I am considering using a CNC beam saw to cut some MDF. I need to know if this type of machine would leave any saw marks on the cut surfaces of the material. Basically, I need to find a way of cutting a large sheet of MDF (30mm thinkness) into 12mm strips. But finding a way to do this without leaving tool marks of the material. I've considered abrasive waterjet and a CNC router but now someone has suggested that a CNC beam saw might be the answer. But it is very important that the material is cut very clean with no machining marks at all. Would a beam saw be ideal? Re: Answer given by mega H. Because of the way I want to use the material cutting 30mm strips from 12mm thickness mdf would not be possible. Also, I would need the cut surface of the MDF totally free of machining marks so that the grain of the MDF is extremely crisp and clear. I have tried sanding the MDF and that destroys the grain. If a drum sander was used would the finish be as clear and crisp as if the material was cut using say a router or even a abrasive waterjet?
