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 misunderstood may be there would be more “room” for tolerance to save manufacturing cost. It is a process of continues improvement, getting new experiences and extend our knowledges. Why do not to do it together? I am available for your questions, ready to provide GD&T course. Let me know how can I help you?
