Precision machining technology:

The so-called precision machining, refers to the processing precision and surface quality to reach a very high degree of processing technology.Different development period. Its technical index is somewhat different.

In industrial developed countries, the average factory can steadily grasp the processing accuracy is 1 m.However, precision machining can control the machining precision below 0.1 m and the machining surface roughness Ra within the range of 0.1~0.02 m.There are mainly precision turning, precision milling and precision boring and so on.

The essence of precision cutting and ordinary cutting is the same, is the material in the role of the tool, shear fracture, friction extrusion and sliding process, but in the precision cutting, the use of micro cutting method, cutting depth is small, chip formation process has its particularity.

In the process of precision cutting, the cutting function is mainly assumed by the cutting edge arc of the tool.Under the condition of orthogonal cutting, the force of any particle I at the cutting edge arc is analyzed.

Since it is an orthogonal cutting, particle I has only two cutting forces, namely, horizontal force Fzi and vertical force Fyi.The horizontal force Fzi makes the particle of the material to be cut move forward and form chips by extrusion, while the vertical force Fyi will be pressed by the cutting material to the workpiece to be cut, which cannot constitute the chip formation condition.

The final formation of chips depends on the ratio of the cutting force Fyi to Fzi acting on the particle.
