In addition to the technological process of CNC lathe processing, CNC lathe processing must also have the principle of process division. So what are our CNC lathe machining process? What is the specific process? Let’s take a look at it in detail. Look.
Generally speaking, CNC numerical control lathe processing technology mainly includes the following contents:
1. Select and confirm the parts and contents processed by CNC lathes;
2. The CNC machining process analysis of the part drawing;
Three, CNC numerical control lathe processing technology design;
Fourth, the mathematical processing of parts drawings;
5. Compile a list of processing procedures;
6. Make the control medium according to the program list;
Seven, program verification and modification;
8. First piece trial production and on-site problem handling;
Nine, the finalization and filing of CNC lathe processing documents.
There are two different principles for dividing the machining process of CNC lathes, that is, the principle of process concentration and the principle of process dispersion.
1. The principle of process concentration
The principle of concentration of CNC lathe machining process is that no process contains as much machining content as possible, thereby reducing the total number of machining. The principle of centralization of CNC lathe machining process is suitable for high-efficiency special equipment and workpiece processing on CNC lathes.
The advantages of using the principle of process concentration are: improve production efficiency, reduce the number of processes, shorten the process route, simplify production planning and production organization, reduce the number of basics, reduce the number of operators and floor space; reduce the number of workpiece clamping times, which not only guarantees processing The mutual position accuracy between the surfaces also reduces the number of fixtures and the clamping of the workpiece auxiliary time. However, CNC lathe processing equipment and industrial equipment have large investment, troublesome adjustment and maintenance, and long production preparation period, which is not conducive to production conversion.
Second, the principle of decentralization of CNC machining programs
Process decentralization refers to dispersing the processing of workpieces in multiple CNC lathe processing processes, and the processing content of each process is small. The principle of processing program dispersion is suitable for processing equipment and processing equipment with a simple structure.
The advantages of adopting the principle of process decentralization are: processing equipment and process equipment are easy to operate, easy to adjust and maintain, and easy to transfer to production; it is conducive to reasonable selection of cutting parameters and reducing motor time. However, the process route is long, the area is large, there are many equipment and workers, and the processing accuracy is greatly affected by the operator’s technical level.
