Cnc processing process division principle
Jan 14, 2019

The division of the cnc processing process can take two different principles, namely the principle of process concentration and the principle of process dispersion.

(1) Principle of process concentration

The principle of cnc processing process concentration means that the process does not include as much processing content as possible, so that the total number of processes is reduced. The cnc machining process concentration principle applies to workpiece machining on high-efficiency special-purpose equipment and CNC machine tools. The advantages of adopting the principle of process concentration are: improving production efficiency; reducing the number of processes, shortening the process route, simplifying production planning and production organization work; reducing the number of foundations, the number of workers and the floor space; reducing the number of workpieces to be clamped, not only guarantees The mutual positional accuracy between the machined surfaces and the number of fixtures and the auxiliary time for clamping the workpiece. However, cnc processing equipment and industrial equipment investment is large, adjustment and maintenance is more troublesome, and the production preparation cycle is longer, which is not conducive to conversion.

(2) Cnc processing process dispersion principle

The process dispersion is to disperse the processing of the workpiece in a large number of cnc processing steps, and the processing content of each process is small. The principle of cnc processing process dispersion is applicable to processing equipment and process equipment with simple structure. The advantage of adopting the principle of process dispersion is that the processing equipment and process equipment are simple to operate, convenient to adjust and maintain, and easy to change production; it is beneficial to select a reasonable cutting amount and reduce maneuver time. However, the process route is long, the floor space is large, the number of equipment and workers required is large, and the processing accuracy is greatly affected by the technical level of the operator.
