Process
Four stages, each with a gate that can reject the work of the stage before it. This is the part of the job we have built and measured; it is what we ask a buyer to judge us on today.
Dimensions are read from the supplied print into a parametric model in which every value traces back to a driving parameter — a measured feature, a declared design choice, or a named handbook fraction. Change the input and the part follows.
The gate: interference, wall thickness and lug edge distance are checked in pure arithmetic before any CAD application opens, and the enclosed area is computed in closed form. A part that fails its own checks never reaches a CAD seat, a machine, or a quote.
Machining features are recovered from the solid itself rather than from a parts list, so an operation cannot be omitted just because nobody wrote it down.
The gate: total planned material removal must equal stock volume minus part volume. Matching features to operations only proves operations were emitted; the volume balance is what proves none is missing. This check has caught a missing operation in our own work.
Cutter paths are generated to a closed-form offset of the profile rather than a sampled approximation, and posted for the target control.
The gate: the cutter is selected from the geometry — an outside profile cannot cut a corner sharper than its own tool radius, so a tool too large for a fillet is refused with the reason stated. Path order is checked as well as path membership, because a path can lie inside the boundary at every point and still cross the part between them.
Every posted program is executed against a stock model and compared to the intended part.
The gate: gouges into finished geometry and rapid moves through material are the failures a correct-looking program hides, and they are what this stage exists to find. It has caught a gouge that the geometry checks passed.
Scope
The verified chain is proven on a defined family of prismatic parts. It is not a general-purpose CAM replacement, and we will not present it as one. Where a part falls outside the family, the chain is built to refuse rather than to approximate — and a refusal reaches you as a question, not as a quote with a hidden assumption in it.
Extending the family is ordinary engineering work: each new operation earns its place by being measured against a closed form, with a control that fails. We would rather tell you a part is outside scope at enquiry than have it surface once metal is being cut.
The measured results behind each gate are on the quality page.
