Casting and machining FAI: proving a part made in two stages
A first article for a cast and machined part has to prove the casting, the machining and the link between them. Here is the evidence to ask for and the gaps that cause disputes.
Drawings, tooling, quality and landed cost, from the team that runs the programmes.

A first article for a cast and machined part has to prove the casting, the machining and the link between them. Here is the evidence to ask for and the gaps that cause disputes.
The practical split between turned and milled parts, the features that force one process, and where a second setup costs more than the part.
An aluminium housing has to keep water out, carry fault current and move heat. The casting and the machining have to be designed for all three at once.
How cavity count, die steel, thermal control and maintenance set the tooling price and the number of shots you can expect before a refurbishment.
A side by side view for buyers comparing the two markets on process depth, tooling, freight and the trade agreements that decide the landed cost.
Wire, bobbin, winding time and test: where the money goes in a wound part, and which design changes actually move the price.
Four measurements catch most coil faults, provided each is made at the right point in the build and against a stated limit.
A battery disconnect has to break DC at full current without a natural zero. Precharge, blowout, material and weld detection decide whether it does.
The variables that decide joint strength, the defects that hide under a clean staked head, and the checks that catch them.
Ownership on paper is not the same as access on the floor. How to register, mark, hold and recover tooling before a supplier stops answering.
A coil turns current into a magnetic field, or a changing field into current. A plain language guide to the winding families, the cores and the parameters that define a coil.
A first article for a wound part is more than a dimensional report. What to balloon, what to measure, which process records to collect and how a coil submission differs from a stamped part.
The guides are built around the same questions as the free tools. Size a busbar, check an ISO 2768 callout, build a first article report or compare landed cost.
