Checking flatness with 3 points
WebSo for a consistent-width gap, this "light and ruler" test would make the issue appear worse in the centre, which naturally makes us think "the bed is warped". The wide angles of the light sources also means that very little light is hitting the gap perpendicularly or straight-on, and instead hits this gap at an angle. WebDec 20, 2014 · All points that are on the referenced feature must in the tolerance zone. Remember: Parallelism does not directly control the angle of the referenced surface; it controls the envelope (like flatness) where the surface needs to be. The goal is to ensure all points are within a specified tolerance distance away from their corresponding datum …
