FASTCUBE Fixture Builder
From STEP data to a production-ready welding fixture in minutes
Automatically generate modular welding and cutting fixtures for high-mix, low-volume production. Read the STEP model directly, get a production-ready fixture design and export laser-cuttable DXF/STEP files, with less dependence on CAD resources.
What holds production up is often not the robot, but the fixture
In many welding and cutting processes the real bottleneck is not automation itself, but getting the right fixture in time.
CAD resources are the bottleneck
Engineering and CAD capacity is limited; fixtures have to be designed, validated and approved, and production preparation drags on.
Improvising at the welding table
When fixtures are not ready in time, the shop floor improvises by hand: clamping takes longer and the process is hard to repeat reliably.
High mix and tight deadlines
Many variants, small batches and frequent changes make traditional fixture design slow and expensive and hard to scale economically.
The usual way
From part change to fixture ready often takes days
- 1 Part change
- 2 CAD design
- 3 Drawings
- 4 Coordination with manufacturing
- 5 Manufacturing data and laser cutting
Typical result: long preparation, heavy dependence on engineering capacity, and manual coordination and rework slowing the start of production.
With FASTCUBE Fixture Builder
From STEP data to fixture prototype in minutes to hours
- 1 Upload the STEP model
- 2 Generate the fixture
- 3 Adjust the parameters
- 4 Export DXF / STEP
- 5 Manufacture and assemble
Typical result: fixtures ready sooner, less drawing work, faster response to changes, and data that goes straight to laser cutting and assembly.
Three steps from STEP model to production fixture
-
01Upload STEP, generate the fixture
Import the part model; the base plate and support plate structure is generated automatically.
-
02Adjust plates and parameters
Add or move support plates and set the orientation and height of the part.
-
03Export DXF / STEP
Export the nesting result, cut it straight on the laser cutter and assemble it using the markings and interlocks.
Fixture design effort
up to 75% less
No time-consuming CAD design, drawings or manual coordination: from STEP import straight to production-ready DXF/STEP.
Manufacturing data, ready to use
Standardised data for fixture design and production, with no manual rework.
- DXF files for laser cutting
- STEP data for further processing
- Parametrically generated base and support plates
- Assembly aided by markings and interlocks
- Standardised hole patterns and geometries
Faster fixture design, more flexible production
Faster start of production
Less waiting for design and manufacturing data, so new fixtures reach production sooner.
Less load on engineering
Less routine work for CAD and engineering teams; a change turns directly into production-ready data.
Less improvising on the shop floor
Standardised, reusable fixture components mean less manual improvising and a more stable process.
Faster response to changes
Variants and part changes only need a parameter change, not a whole new fixture process.
Better equipment utilisation
With fixtures ready sooner, robots, laser cutters and stations are used more fully.
Reproducible results
Parametric logic and standard components raise the quality, consistency and repeatability of fixture design.
