How it Works

Nucleo Fixture creates an interlocked grid of X and Y  fixture blades connected to a mating base plate from an imported solid CAD model. The top profile of each X or Y blade matches the underside of the component at the blade’s insertion position, creating a “cradle” into which the component is located. Nucleo Fixture includes a range of standard CAD translators and optional translators for most popular CAD systems. These include IGES, Solidworks, SolidEdge, IronCAD, Inventor DWG and DXF, CATIA, Pro Engineer, STEP and Unigraphics.

Return on Investment

Compared to traditional fixture costs, Nucleo Fixture results in enough overall savings to pay for itself within a small number of fixture runs.

"This software has changed the game for our fixtures in accuracy and development time. 

Installing them is a breeze and I would highly recommend. 

For example, I finished 32 fixtures in 2 weeks. Before, it would’ve taken 2 weeks for a smaller fixture. 

I’ve also made line fixtures for work holding while installing other components. 

They also have a jigsaw feature that breaks up the base plate on larger items that dovetail together."

Apex Tool Group used Nucleo to help automate the manufacture of toolboxes in their robot cell.  The design included pneumatic clamps into the fixture.

Gilbert manufacture heavy equipment for industries including forestry and construction. This FaaS® project used 0.25" material for the heavy-weight part and "gripper points" to offset the fixture from the part surface. These radii - spaced along the fixture blade peripheries - allow for any adjustment that may be necessary and less friction/heat transfer between the weldment and fixture.
