WebFeatures. Samples up to outer diameter φ130 mm are measurable. (Up to φ100 mm for flatness measurement) Applicable to wafers (silicon, compound, oxide or glass), metallic fragments, disks (aluminum or glass), or user-defined shaped parts, etc. Applicable to mirrored/non-mirrored surface, transparent samples, perforated samples, or atypical ... WebFlatness is a form control, because it is used to control the form or shape of a feature. It controls how much a surface on a part may deviate from an ideal plane. The Tolerance Zone for a Flatness Tolerance is based on two parallel planes. One lies at the peak of the tallest irregularity in the surface. The other lies at the deepest trough of ...
