Geometric Dimensioning and Tolerancing
Helen, meaning light, who is also a demigodess according Greek mythology. Advanced measurement solutions represented by scanners, using light in 3D measurement. A structured light patterns – stripes, if you like call it Zebra is projected onto an object, when their distorsions are captured by cameras, from multiple angles. Angles between two cameras introduce triangulation […]
Method of measurement: Contact (point-based systems) Coordinate Measurement Machine (+) High accuracy measurement (+) Good for measurement of geometrical features: Diameter of Holes Diameter of Pins Cylindricity Roundness Coaxiality Concentricity (-) Restricted measurement area (-) Operated under temperature-controlled environment (-) Component to be measured must be allowed to be stabilized at that temperature (-) Access […]
Products manufactured first time, coming off either from work station or from assembly line are called first article and they are subject of inspection. Purpose of first article inspection is to check, if part or assembly is made according specification represented by drawing and by other physical, functional requirements and legal regulations. Planning, purchase order […]
Geometric Dimensioning and Tolerancing. Among engineers is a kind of engineering language. This is the way how we are expressing our ideas to send it to production. Obviously everybody who is working at design, manufacturing or quality department need to understand that and apply it. Sometimes can happen that something went wrong, may be just […]
