In the process of machining, it is often difficult to use standard tools for machining, so the manufacture of non-standard tools is very important for machining.
The use of non-standard tools in metal cutting is often seen in milling, so this paper mainly introduces the manufacture of non-standard tools in milling.
Because the production of standard tools is aimed at the cutting of common metal parts or non-metallic parts with a wide range of surfaces, when the hardness of the workpiece is increased due to overheating treatment, or the workpiece is stainless steel, it is very easy to stick to the tool, and there are also some cases where the surface geometry of the workpiece is very complex, or the machined surface has high roughness requirements, the standard tools can not meet the needs of processing. Therefore, in the process of machining, it is necessary to carry out targeted design for the material of the tool, the geometric shape of the edge, the geometric angle, etc., which can be divided into two categories: special customization and non-special customization.
