Factors affecting cutting speed, depth and feed rate

　 The general conditions of cutting speed, depth and feed rate are the rigidity of machine tools, tools, tools and workpieces
Cutting feed rate; workpiece precision and surface roughness; tool life expectancy and maximum productivity; type of cutting fluid, cooling method
Hardness and heat treatment; number of workpieces; life of machine tools.
1, the tool material is different, the maximum allowable cutting speed is also different. High speed steel with high temperature cutting speed less than 50m / min, carbide cutter
High temperature cutting speed up to 100M / min or above, the cutting temperature of ceramic tools can be as high as 1000m / min.
2, the hardness of workpiece material will affect the cutting speed of the tool, the same cutting tool cutting hard material speed should be reduced, while the processing of soft materials
The cutting speed can be improved.
3, the use of cutting tool life (life) requires a long time, it should be used at low cutting speed. On the contrary, the higher cutting speed can be used.
4, cutting depth and feed volume, cutting resistance is also large, cutting heat will increase, so cutting speed should be reduced.
5, the shape of the tool, the size of the angle, the sharpness of the cutting edge will affect the selection of cutting speed.
Among these factors, cutting speed, cutting depth and cutting feed rate are the main factors. Direct cutting speed
Ring cutting efficiency. If the cutting speed is too small, the cutting time will be lengthened, the tool can not play its function; if the cutting speed is too fast, although can
Shorten the cutting time, but the tool is easy to produce high heat, affecting the tool life. The influence of cutting tool material on the cutting speed
Most main.
