(1) High productivity When milling, the milling cutter rotates continuously and allows high milling speed, so it has high productivity.

(2) Interrupted cutting When milling, each tooth is in intermittent cutting, especially in end milling, the milling force fluctuates greatly, so vibration is unavoidable. When the frequency of vibration is the same as or a multiple of the natural frequency of the machine tool, the vibration is most serious. In addition, when high-speed milling, the cutter teeth are subjected to periodic cold and thermal shocks, which are prone to cracks and chipping, which reduces the durability of the cutter.

(3) Multi-knife and multi-blade cutting The milling cutter has many teeth, and the total length of the cutting edge is large, which is conducive to improving the durability and productivity of the tool, and has many advantages. But there are also the following two problems: First, the cutter teeth are prone to radial runout, which will cause uneven load on the cutter teeth, uneven wear, and affect the quality of the machined surface; second, the chip space of the cutter teeth must be sufficient. , otherwise it will damage the teeth.

(4) Different milling methods According to different processing conditions, in order to improve tool durability and productivity, different milling methods can be selected, such as up-cut milling, climb milling or symmetrical milling, asymmetrical milling.

Refers to a variety of cutting-edge steel engraving (ENGRAVING) tools, with a wooden handle at the back, usually round for the comfort of the palm. Some carving knives have oval cross-sections, while others have diamond-shaped cross-sections, and the tops are all obliquely pointed. The tip of the tool with a rectangular cross-section is a sloping surface, with blunt, round and pointed shapes. The tip and width of the blade is determined by the depth and width of the line to be engraved. Carving knives come in a variety of sizes and shapes. Both curved and straight handles are for ease of use.

CNC milling cutters can be divided into
