Standard Tolerances for Sheet Metal

Standard tolerance values for laser cutting, bending and welding.

Laser cutting: ±0.1mm (thin sheet), ±0.2mm (thick)

CNC bending: ±0.2mm on dimensions, ±0.5° angle

Welding: ±0.5mm on overall dimension

Machining: ±0.05mm standard, ±0.02mm on request

Specify tighter tolerance only on mating dimensions; it costs more.
