Sorry Martin; this is a CNC Router issue. I think the other answers below are moving me in the correct direction. Thanks for your imput though.I assume you mean a printed vinyl with wood effect on? if so flood coat the substrate with the vinyl and then route it. As long as the tool is nice and sharp it will cut very neatly through both both
Thanks Sandman. I will look at your approach to see if it will help reduce my time routing and finishing the signs. Currently I am having to do a lot of hand finishing to get the "offset" areas to blend into the wood grain effect.During the design process you need to select the vectors of the actual letters, graphics and border to add your wood grain. My wood grain is a texture file so I select the vectors, add it as a texture, set the depth, hit add or subtract depending on how you are modeling it. Next is the important step. You need to make offset vectors outwards from your letters equal to HALF the diameter of the ball nose bit you are going to use to carve the wood grain and use those offset vectors when you create the tool path. Most programs use the center of the bit in the tool path to the vector so if you use the actual vectors for the letters, your tool will cut into the letter by half the diameter.
Thanks Brian. I will look at your approach to see if it will help reduce my time routing and finishing the signs. Currently I am having to do a lot of hand finishing to get the "offset" areas to blend into the wood grain effect. Your approach to "pocket" letters and graphics as a seperate step, may be my next step.I have transitioned away from routing letters while using a texture or wood grain just from the finished look. I have moved to routing the texture over the entire surface, pocketing for the letters, milling letters to fit in pocket so that the texture goes right up to the straight wall. Much cleaner and believe it or not I finish the letters separate from the sign and glue in place and time is a push if not advantage to creation when doing a gilded letter.
doesnt anybody own chisels anymore? it probably takes 3x as long to program a 1/2 hrs worth of chisel work
