DXF preparation checklist for a laser cutting RFQ
The ten checks that stop a laser cutting RFQ bouncing: scale, closed contours, duplicate entities, kerf compensation, bend layers and file naming.

How sheet metal nesting cuts laser part cost
How sheet metal nesting sets the price of a cut part: yield from 63% to 92% on one sheet, kerf and web arithmetic, skeleton design and remnant control.

Deburring and edge quality after laser cutting
What sets edge quality after laser cutting, which burrs matter for coating and welding, thickness limits on a 12 kW fibre laser, and how to specify deburring.

Laser cutting tolerances for OEM parts: kerf, holes and flatness
Thickness-by-thickness laser cutting tolerances for OEM parts, where the millimetres come from, and how to dimension a DXF so the cut passes first-off.

Laser-cut and bent enclosures
How a 19-inch rack enclosure is cut, bent, coated and inspected: fixed dimensions, a rail deflection example, coating specification and the FAI record.

Laser-cut components for genset canopies: panel limits
Laser-cut components for genset canopies: louvre and perforation open area, panel thickness, base frame, tooling crossover and coating that lasts.

Laser-cut elevator frame sections: cut file to fit-up
How laser-cut elevator frame sections hold car and counterweight geometry: cut-file rules, hole-to-bend limits, weld distortion and coating checks.

Laser cutting for prototypes and production volumes
Why a five-part lot costs 786 seconds of work per part and a thousand-part lot costs 93, and how the nest, drawing and inspection change as volume rises.

Go from reading to checking
The guides follow the same questions as the free tools. Size a press, check a bend, estimate a cut part or build the RFQ pack.
