From the drawing board
Technical notes written by the engineers who issue the work — what we have learned about tolerancing, shop drawings, machining and taking a concept to production.
Tolerancing for laser-cut sheet metal: where ±0.1 mm costs you money
Tight tolerances on a laser-cut part are usually free in CAD and expensive on the shop floor. Here is where they actually matter — and where they quietly add cost.
Beautiful renders do not help the person on site at 7am. These are the dimensions and details that decide whether a fit-out goes in clean.
The fear is always the same: send the work out and lose the standards, the revisions and the institutional knowledge. Here is the operating model that prevents it.
Geometric tolerancing earns its keep on four or five features per drawing. Everywhere else it is decoration that slows down inspection.
Most production programmes were written once, under deadline, and never revisited. An audit typically recovers double-digit percentages without new tooling.
A mesh is not a model. Turning scan data into parametric CAD is where the value is — and where most reverse engineering projects stop too early.
