3 Gorgeous Engraving Techniques You’d Absolutely Love

1. CNC Rotary engraving

• CNC Rotary engraving is very similar to the traditional – ancient hand carving technique. This milling machine, with only one difference from the traditional carving, is ideal for highly detailed engravings.
  The Rotary machine is designed to produce ideal copies of a piece with its rich details, in well-polished, precise and short-term manner.

• CNC (computer numerical control) miller has a 3-axis tool, which follows and interprets certain path (lines) pre-drawn in a CAD software by the designer.
  G code – is the language which tells the rotary machine to cut through the material or cut (engrave) to a certain depth. It also reads inside the line, outside the line and on the line cutting commands.

• 3 axis
  X axes – runs from left to right
  Y axes – runs from top to bottom
  Z axes – is the zero point and the process

2. CNC Laser engraving

The laser engraving sends laser pulses to make incisions – burns or cuts host of materials.
The laser head runs back and forth to produce clear cut and very detailed engravings.
The materials that work wonders for laser engraving are Acrylic, wood, Lexan, etc.

• Depending on the final effect, we can control the direction, speed, depth and the size of the detailed engravings on different surface properties.

• This computerized machine must have illustrator files for the laser to cut at a certain thickness and certain lines.

• Different laser machines offer variety of depths to personalize and customize the suitable material. For example, dense materials can handle up to 0.020 deep engravings.

3. 3D engraving

At a touch of a button, CNC milling can create 3D signs. The Milling machine can engrave graphics, ornaments to a fine piece of artwork.
3D design process is practiced on materials such as Wood(of course), Acrylic and even metal.
The multi-spindle router creates squiggly, curved lines with a batch of extensive CNC tools which highly resembles manual carving – but done at less time and reduced manpower.
But there’s more than that.

Techniques
3d engraving on the CNC routers is similar to bright-cut engraving with V-point engraving tools. The G-code language (the encrypted dialect of the CNC routers) interprets the vectors and raster images from the results obtained by the software. The V-point can vary to 360 degrees. The tools mimic the cutting and texturing motion of hand tools such as roulets and burnishers (Source: Wikipedia — engraving) by removing the material as the piece rotates on the 360 degrees rotary.
