This is a CNC egg shell bas-relief engraving procedure.

Step 1: Prepare a Greyscale Image

Get the greyscale image from the net or create your own greyscale image by 3D software.


Remark :

Greyscale image is not really a black and white photo.

It is in fact a file records the X, Y and Z values of an object.

The cutting depth depends on the brightness of the image.

Step 2: Compress the Height of the Image to About 77% of Original

The aim is to compensate the image distortion from flat surface to curve surface.

Step 3: Prepae the G-codes From the Image

Use ArtCam, Mach3 or else.

Step 4: Do the Egg Shell Engraving by a CNC Egg Shell Engraving Machine

The maximum depth of engraving is 0.35mm.

The thickness of the goose egg shell is about 0.55mm.

Step 5: Clean the Egg Shell by Bleaching Solution
