Why does this fretwork generator adjust the exact cell pitch slightly to fit the panel?

If a fixed pattern is simply clipped by a rectangular border, it leaves tiny, fragile partial cutouts and paper-thin slivers along the frame edges that break off or catch on CNC bits. Our algorithm integer-quantizes the column and row counts so every single geometric cutout is complete and symmetrical.

Can I cut these decorative panels on both a CNC router and a laser cutter?

Yes! The stepped diamond and corner-aperture geometry uses straight vectors and chamfers that cut cleanly with both a 0.15mm laser beam and a 3.175mm (1/8 inch) CNC router endmill.

Are mounting holes included in the panel border?

Yes, four Ø5.0mm mounting holes are centered within the four corners of the structural border margin for architectural standoffs or M5 fasteners.

What minimum web bridge thickness is enforced?

The engine enforces a minimum web bridge of 4.0mm or 1.5× your material thickness (whichever is greater) so MDF, plywood, and acrylic panels remain rigid over large spans.

Structural Geometry & Material Reference (AWI Architectural Woodwork & CNC Open-Area Rigidity Standard)

Architectural CNC fretwork panels, laser-cut privacy screens, and decorative cabinet radiator grilles require a precise balance between open visual aperture and structural web thickness so the sheet does not warp, chatter on the router bed, or snap during handling. Our parametric CNC fretwork generator builds a rigid outer structural frame border around a symmetrical diamond-and-quatrefoil geometric lattice array, automatically scaling the repeating cell count (C × R) and structural web bridges (`W_web >= max(4mm, 1.5*T)`) to prevent narrow uncut slivers at the panel edges.

Solid Perimeter Frame Margin (M_border)

M_border = max(14 mm, min(L, W) * 0.08)

Preserves a continuous solid structural border around all four edges of the panel for cabinet rabbets, standoffs, or wall mounting.

Inter-Cell Structural Web Bridge (W_web)

W_web = max(4.0 mm, T * 1.5)

Guarantees that the material bridge between adjacent lattice cutouts is at least 1.5× material thickness to prevent heat scorching on lasers or tear-out on CNC routers.

Normalized Cell Pitch across Interior Aperture (P_x, P_y)

P_x = (L - 2 * M_border) / Cols, P_y = (W - 2 * M_border) / Rows

Integer-quantizes the number of columns and rows so every diamond and corner aperture cell terminates cleanly against the solid frame border.
