1, Effect on cutting temperature: cutting speed, feed rate, back-feeding amount. Effect on cutting force: back-feeding amount, feed rate, cutting speed. The impact on the durability of the tool: cutting speed, feed rate, the amount of back eaten. 2, When the amount of back-eating knife doubles, the cutting force doubles; When the feed rate is…
CNC machining refers to the process of removing materials from various tools in the center of high-speed precision machine tools. Five-axis machining is a machine that can move tools or parts on five different axes simultaneously. The basic machining operations are on three spindles, the X-axis, the Y-axis and the Z-axis; however, the five-axis CNC…
Cold stamping is a pressure method that uses a die installed on a press to apply pressure to the material to cause it to separate or plastically deform, thereby obtaining the required parts (commonly known as stamping or punching). Because it is usually processed at the room temperature of the press, it is called cold…
