Table of Contents Introductory The influence of the surface roughness of a part on its use performance is multifaceted. Therefore, in the selection of surface roughness parameters, should be able to fully and reasonably reflect the real situation of the surface micro-geometry. For most surfaces, evaluators generally use only the
Table of Contents Usually contains more than 12% chromium or nickel content of more than 8% of the alloy steel called stainless steel. More Cr and Ni improve stainless steel’s properties, boosting corrosion resistance and strength above 450 ℃. Therefore, many industries widely use it in aerospace, chemical, petroleum, construction, food

Table of Contents Introduction Definition and Importance Sheet metal bending is a core manufacturing process in which flat metal sheets are transformed into three-dimensional shapes through controlled plastic deformation. Using tools such as press brakes and dies, materials are bent along straight axes to achieve functional, often highly precise geometries.
With the development of society, aircraft, aerospace vehicles, drones are increasing, the demand for thin-walled parts is increasing. Thin-walled parts internal hollowing, high excision rate is generally more than 90%. Thin-walled parts require high-precision milling with heavy metal removal, but low rigidity and easy deformation reduce milling efficiency. Milling thin-walled
In the processing of metal materials, heat treatment technology is widely used. The technology through heating, holding and cooling steps, change the internal organization of metal materials, and then improve their mechanical properties and stability. However, the deformation and cracking problems generated in the heat treatment process have always been
