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 […]
Most of the businesses have to be very considerate about their budged. Making profit, quality management system needs to be adjusted in a cost effective way. The most common mistake what managers do, in order to save, is underestimating importance of metrology system and neglecting them. It all starts with extending calibration periods, reducing samples […]
Just like every other products, measuring instruments also losing their properties over time. How time, environment, usage, or other conditions influence properties will be known through performing regular calibrations. By calibrating instrument, we can determine stability, drift, or other properties to predict reliability of measured data and measuring instrument itself. According my common experience I […]
In our everyday language as well as in industrial world quite often used terms are accuracy and precision. Usually these two words are associated either with measurement or manufacturing. What is the accuracy of this measurement? Or How precise is your manufacturing? Our first thought is related rather to a level of quality, something related […]
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 […]
Before we dive in to point out about importance of metrology, I would like to take a chance and explain the meaning of the word “Metrology”. Metrology word comes from ancient Greek as a combination of two greek words Metron and logos, Metron = measure logos= behind argument. In modern world understanding is a Science […]
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 […]
Do you speak Engineering? You don’t? Get an introduction of GD&T ASME 14.5M – 2009 combined with measurement techniques you need to know! I am available for face to face, group or online courses. Ask me and I teach you Engineering language!
Did you send your RTD for calibration? Did you get Certificate of Calibration? and now you have realized your unit ask for coefficients? So are you in doubt what to do? Are you calling your laboratory, but they do not want to deal with you? Or just they do not want to share with you […]
