The Technology
The Tool-Less technology is a CNC machining
and fabrication process using assembly
and machining techniques borrowed from
the sheet metal fabrication and (wood)
cabinet making industries.
The technology is used to make fabricated
enclosures, “hog-out” enclosures, bezels,
machined parts and assemblies.

 |
 |
 |
| Step 1.
Design the
enclosure starting
from a dimensioned
drawing or CAD
file showing the
circuit boards
and electronic
components oriented
in space. |
| Step 2. Generate
the CNC code that
drives all the
machining and bending
operations. |
| Step 3. Machine
the sheet to add
openings, vents
and recesses.
|
|
| Step 4.
Cut
individual pieces
from sheet. |
| Step 5.
Prepare
joint and edge
details on routing
machines. All joints
feature a modified
tongue-and-groove
design. |
| Step 6.
Score
the sheet with
bending cuts on
a custom table
saw. These v-shaped
bending cuts extend
halfway through
the sheet and boost
the bending precision.
|
|
| Step 7.
Bend
the pieces in a
computerized thermal
bending machine
that resembles
a sheet metal brake
press. |
| Step 8.
Heat
stake metal inserts
into bosses. Install
the bosses into
machined recesses
in the sheet. |
| Step 9. Assemble
the pieces using
a solvent-bonding
process. |
| Step 10. Perform
secondary operations
like painting,
EMI shielding,
and latch or hinge
installations. |
