Engraving toolpaths for router bits
I'm just getting involved in engraving, and I'm curious about the need for a very good finish quality on the bottom of engraved pockets. No matter how well a tool is 'touched off' there are very minor differences in depth when doing multi-tool pocketing, so I'm wondering if a finish pass in Z is also worth doing? I.E. pocket all shapes (lettering, etc) with multiple tools leaving .005 for a finish pass both on the profile AND the depth, Then, since most of the material has been removed you can then clean up the bottom and sides perfectly with the finishing tool at a higher feed rate. Does this seem like a reasonabe strategy?
