Mechanical processing includes filament winding, laser cutting, rework, metal bonding, metal wire drawing, plasma cutting, precision welding, roll forming, metal plate bending forming, die forging, water jet cutting and precision welding.
brief introduction
With the rapid development of machining technology, many advanced machining technologies and methods have emerged, such as micromachining technology, rapid prototyping technology and precision ultra-precision machining technology.
Mechanical parts are composed of several curved surfaces. To study the relative relationship between parts' surfaces, it is necessary to determine a datum, which is the point, line and surface used to determine the position of other points, lines and surfaces on the parts. According to their different functions, benchmarks can be divided into design benchmarks and process benchmarks.
