Forged Path Automation | We are process engineers, not just robot integrators — Landrum, SC
Forged Path Automation designs, builds, and supports turnkey robotic finishing and cleaning cells from Landrum, South Carolina, for manufacturers in the gas turbine, aerospace, and automotive industries.
Transportation is the largest end use for aluminum in the United States. The U.S. Geological Survey, in its Mineral Commodity Summaries published in February 2026, put transportation at 36 percent of domestic aluminum consumption, ahead of packaging at 24 percent and building at 13 percent.
That figure has a practical edge for anyone running a finishing operation. More aluminum in vehicles means more aluminum arriving at a bench that was most likely set up around iron and steel, and the two materials do not respond the same way to an abrasive.
The material does not fail the same way
Grey iron is brittle at the burr. It fractures away and leaves an edge behind.
Aluminum is soft and ductile, so it moves instead. The burr folds over, smears along the edge, or re-attaches somewhere it was not wanted. An abrasive selected for iron loads with aluminum within a few parts, and a loaded abrasive stops cutting and starts rubbing. Rubbing puts heat into a part that conducts heat quickly and has thin sections in places.
The operator at a hand bench compensates without naming any of this. They back off, change the wheel more often, and work the edge differently. A cell has to be told.
What makes deburring cast aluminum different from iron or steel?
Aluminum is soft and ductile, so burrs fold and smear rather than fracture away, and abrasives load with material and stop cutting. The dust is also combustible. Both facts change the cell: abrasive selection and contact force on one side, dust collection and ignition control on the other.
The dust is a design input, not a housekeeping detail
This is the part that gets discovered late.
In Hazard Communication Guidance for Combustible Dusts, publication 3371-08, issued in 2009, OSHA lists metal dusts including aluminum among combustible dusts. Its table places aluminum in the St 3 class, at a Kst above 300 — the most severe classification the document assigns.
OSHA sets out five elements it calls the dust explosion pentagon: combustible dust, an ignition source, oxygen, dispersion in sufficient concentration, and confinement of the dust cloud. Remove any one and an explosion cannot occur. The guidance also notes that larger metal particles still carry a deflagration hazard, because handling can abrade them into smaller ones, and that a primary event can shake settled dust loose and cause more destructive secondary ones.
A sealed robotic enclosure supplies confinement. An abrasive operation supplies dispersion and a plausible ignition source. Three of the five arrive with the cell.
What that changes inside the cell
OSHA’s own recommendations read as a specification list once the operation is automated. Ducts, collectors, and equipment designed so dust does not leak into work areas. Collection systems fitted with relief venting, suppression, or an oxygen-deficient atmosphere. Grounding and bonding against static accumulation. Appropriately classified electrical equipment. Non-sparking tools. Local exhaust ventilation. Settled dust removed on a routine housekeeping schedule rather than when someone notices it.
Whether the operation runs wet or dry is the first fork, and it reaches everything downstream — collection, residue on the part, and what cleaning the part needs before it moves to coating or assembly.
Castings add their own complications
Cast aluminum is not uniform the way an extrusion is. Porosity opens up under an abrasive and changes what the surface looks like mid-pass. Section thickness varies, so heat builds unevenly. Inclusions sit where the model does not show them.
Those are material conditions rather than geometry, which is a different problem from the dimensional variation every casting carries. A cell can be told where to look for a burr and still be wrong about what it finds when it gets there.
Deciding this before the equipment conversation
Deburring cast aluminum belongs in the earliest scoping conversation, alongside part family breadth and volume. It sets abrasive and media selection, contact force, collection strategy, and the enclosure itself — and those commitments are awkward to revisit once steel is cut, which is part of why the cell architecture question comes first.
Deburring cast aluminum is a well-understood process. It is understood differently from deburring iron, and the difference shows up in the cell rather than in the robot.
Forged Path Automation: Robotic Deburring and Finishing Cells in Landrum, SC
Forged Path Automation was founded by process engineers who kept seeing the same problem: automation providers selling equipment without owning the process. We handle system design, tooling, build, programming, installation, training, and support under one contract.
Our Services Include:
- Robotic Finishing Automation — Polishing, buffing, deburring, and sanding cells built for variable parts
- Robotic Cleaning Automation — Part cleaning, surface preparation, and pre-coating cleaning cells
