Reasonable selection of cutting amount for 1. CNC Lathe processing For high-efficiency metal cutting materials, cutting tools and cutting conditions are the 3 main factors. These determine the machining time, tool life and machining quality. 1 a cost-effective processing method must be a reasonable choice of cutting conditions. The 3 elements of CNC lathe machining cutting conditions: cutting speed, feed speed and cutting depth directly cause tool damage. As the cutting speed increases, the tip temperature increases, causing mechanical, chemical and thermal wear. The cutting speed is increased by 20%, and the tool life is reduced by 1/2. Feed conditions for 2. CNC lathe processing The feed conditions are related to the wear of the rear part of the tool in a small range. However, the feed rate is large, the cutting temperature rises, and the rear wear is large. Its effect on the tool is less than the cutting speed. Although the cutting depth has no effect on the cutting speed and feed rate, in the case of small depth cutting, the hardened layer is produced by the cutting material, which also affects the life of the tool. But in actual operation, the selection of tool life for CNC lathe processing is related to tool wear, machining size changes, surface quality, cutting noise and heat treatment. When determining the processing conditions, it is necessary to conduct research according to the actual situation. For difficult-to-machine materials, such as stainless steel and heat-resistant alloys, CNC lathes use coolant or rigid blades.
