However, some hard particles with hardness much higher than that of the base material, such as iron, are often mixed in the workpiece raw material at present, and the hard foreign materials are generally difficult to completely remove because the particle size and the form of the hard foreign materials are not much different from those of explosive particles.
The PBX material has obvious soft brittleness, the base material is elastically deformed under the action of a cutter during turning, and brittle fracture is generated when the deformation exceeds the fracture strength of the material. The hard foreign matters are sheared and broken or particles fall off along with the base material under the action of cutting force, the hard particles slide forwards to form normal falling of chips, and the hard particles can easily adhere to the tool point or the rear tool face of the tool due to the binder in the base material, so that groove marks are left along with the sliding of the cutting process in the machined surface. Turning is taken as a typical continuous cutting, and a tool nose and a workpiece are always in a cutting-in contact state in the cutting process, so that hard particles are more easily adhered to the position of the tool edge and are not easy to fall off, an annular obvious visible groove mark with a certain width is formed on the surface of the workpiece in serious cases, the surface of a product is influenced, the workpiece is scrapped in serious cases, and huge economic loss is generated.
