Tolerance & Accuracy
Tolerance is a condition, not one number.
Material, thickness, plate condition, geometry, thermal input, feature type, secondary processing and measurement method all affect what can be achieved. Reference bands can guide discussion; critical dimensions are confirmed for the actual project.
Laser±0.1 ~ ±0.3 mm reference
Flame±0.5 ~ ±1.0 mm reference
ProjectCritical features confirmed separately
What Changes Accuracy
Apply the tolerance to the right feature and process.
A single nominal band can be misleading when the finished part includes thermally cut edges, machined holes, long strips, bevels or post-process flatness requirements.
Cut profileProcess reference ranges are useful starting points; geometry and thickness still matter.
Holes / boresThermal-cut, drilled and bored features should not share the same assumption about size or position.
Long / narrow partsStraightness and distortion require part-length, support, sequence and measurement context.
BevelsAngle, root face and width need feature-specific acceptance rather than borrowing the outer-profile tolerance.
FlatnessState the measurement area, datum/method and finished state when flatness controls assembly.
MeasurementInstrument, temperature/state, sample and measurement points are part of any defensible numeric claim.
