The basic principle of machining is material removal. It is obtained by cutting the material that makes up the part (in our case, a plastic block). Cutting is carried out by moving a tool in contact with the part, set in high rotation, to obtain the required dimensions, using a machine tool. With this technique, high-precision parts are obtained.
In general, the shapes of the machined surfaces can be flat or rotational. The main machining operations are milling (flat surfaces) and turning (surfaces of revolution). For our sensor, it is of course the shooting that was carried out.
Machining can be applied to many materials such as: steel, aluminium, brass, stainless steel, titanium, plastic and many other materials.
