For cutting the CNC Corel Draw, the drawing was exported to a 12.0 PLT termination to be worked on CNC toolpath software, which is the interface between the two programs.

Once it was placed in the toolpath file were given two different measures of penetration that needed cutting. The engraving was done with 1mm and 12mm cutting, and was cut according to the material.

The cutting material was placed and secured to the table router by a pump power of 10 HP through empty air.

Calibrating working heights were penetration height and material safety height with respect to the worktable.

The cutting speed was specify according to the material, for a work MDF with a feed rate of 8000 mm per minute, and a shear rate of 13000 rpm.

The cutting speed was not enough and the plates were obtained with an excess of material, which was removed with an accurate and sandpaper.

Final Project.
