CNC Project: Cutting the State of California Topographical 3D Map | ToolsToday

Watch step-by-step as we design and carve this beautiful California 3D topographical map from reclaimed walnut. Final dimension measure 14“ wide x 36“ tall x 2-1/2“ high. Step 1 Download the geographical maps from the US Government websites and translate the 2D patterns into 3D design for CNC carving Step 2 Solid Carbide Spiral Plunge Router Bit no. 46272 cuts the perimeter of California State Step 3 ZrN Coated Solid Carbide Spiral Ball Nose Router Bit no. 46495 rough cuts the reclaimed walnut and removes unnecessary material with it’s thick 1/2” tip diameter Step 4 ZrN Coated Solid Carbide Spiral Ball Nose Router Bit no. 46283 uses it’s 1/4” tip diameter to make an intermediate roughing pass Step 5 ZrN Coated Solid Carbide Spiral Ball Nose Router Bit no. 46284 makes the first of two finishing passes with it’s 1/8” tip diameter Step 6 ZrN Coated Solid Carbide Spiral Ball Nose Router Bit no. 46582 utilizes its extremely thin 1/16” tip diameter for the final finishing pass Step
