What are the basic machining methods in machining?

Common machining methods include turning, milling, grinding, boring, drilling, wire cutting, EDM and so on.

Lathe machining is a part of mechanical machining. Lathe machining is mainly to turn rotating workpiece with lathe tool. On the lathe, you can also use drills, reamers, taps, dies and knurling tools for corresponding processing. Lathe is mainly used to process shafts, disks, sleeves and other workpieces with revolving surfaces, and it is the most widely used machine tool in machinery manufacturing and repair shops.

When turning inner and outer cylindrical surfaces, the turning tool moves in the direction parallel to the rotation axis of the workpiece. When turning an end face or cutting a workpiece, the turning tool moves horizontally in the direction perpendicular to the rotation axis of the workpiece. If the trajectory of the turning tool is oblique to the rotation axis of the workpiece, a conical surface can be machined. Forming tool method or tool tip trajectory method can be used to turn the surface of rotating body. When turning, the spindle of the machine tool drives the workpiece to rotate as the main movement; The lathe tool clamped on the tool rest makes feed movement. The cutting speed v is the linear speed (m/min) at the contact point between the machining surface of the rotating workpiece and the turning tool; The cutting depth is the vertical distance (mm) between the surface to be machined and the machined surface of the workpiece in each cutting stroke, but it is the contact length (mm) between the lathe tool and the workpiece perpendicular to the feed direction during cutting and form turning. The feed speed indicates the displacement (mm/r) of the turning tool along the feed direction when the workpiece rotates once, and can also be expressed by the feed speed (mm/min) of the turning tool per minute. When turning ordinary steel with high-speed steel turning tool, the cutting speed is generally 25 ~ 60m/min, and the carbide turning tool can reach 80 ~ 200m/min. When using coated carbide turning tool, the highest cutting speed can reach more than 300 m/min.
