A micrometer is a measuring tool used to precisely measure lengths on small scales. In principle, spiral micrometers can be divided into mechanical micrometers and electronic micrometers. The mechanical micrometer is made according to the principle of spiral magnification.
Calibration is a quantitative comparison. Check the reading of the instrument, it is achieved by measuring the actual standard part, and the deviation between the measured value and the actual value is corrected.
In the machinery industry or automation industry, CAD, CAE, and CAM complement each other. Design with CAD and then manufacture with CAM. CAD is the design process using computer technology, CAE is the use of computer simulation to analyze physical problems, and CAM is the use of computers and computer software to control machines for manufacturing, usually suitable for mass-produced parts.
Quantitative observation for manufacturing cannot rely solely on human senses, such as vision, hearing, touch, etc., but requires special measuring instruments. Measurement refers to the numerical representation of the size of an object based on a certain standard (unit).
The machine tool industry is regarded as an indicator of the country’s degree of industrialization. In recent years, the aerospace and automotive industry demands and today, as the machining accuracy requirements are increasing day by day, mechanical geometric accuracy is still the most important key.
The repair and maintenance of CNC machine tools are very important. Time should be taken in the work to reasonably arrange the inspection work of the machine tools to avoid damage to the work caused by the damage of the machine tools.
