Z-axis depth
Z-axis depth is determined by the material thickness and hole depth.
It can be calculated as: Z-axis depth = hole depth – material thickness.
According to the Raster Braille manual the hole depth should be 1,07mm (0,042”).
You may find that the holes being milled are either too shallow or too deep. If so, use this parameter
to adjust to a suitable setting.
You will see this if the spheres sit too low or too high.
The standard specifies a sphere height of 0,6mm (0,023”).
Example using 3mm Dibond: 1,07mm – 3mm = -1,93mm
Spindle RPM
Spindle RPM is material dependent and may require experimentation. The values shown in the
illustration are suitable for 3mm Dibond.
Drill holes
Drill holes check box should be enabled.

Z-axis Depth
Z-axis depth should initially be set to the material thickness.
This parameter determines the pressure the
Braille Tool
will use to force the sphere into the hole.
If you are using soft materials and notice indentations in the material, you can lower the value to get a
lighter pressure.
On the other hand, if the spheres are not fully inserted into hard materials, like acrylic, you may
increase this value to increase the force used by the
Braille Tool
.
Drill Holes

Braille grade 1 & 2
Grade 1 braille is a letter-by-letter translation of texts.
If you wish to create Grade 1 braille signage you can use any available braille font. These fonts may be
freely available on the internet.
Grade 2 braille introduces abbreviations and contractions for a large number of commonly used
words.
This is the recommended/preferred method of creating braille texts.
For Grade 2 braille you will need dedicated translation software.
Translation software recommendations can be found in the Raster Braille manual supplied with the
Braille Tool
