The economic effect of forging processing can be identified from comparison. The technical and economic effect is carried out by comparative method. When comparing process schemes, there may be more than two schemes. In order to make the conclusion of analysis correct and reliable, the exhaustive method should be used to list the possible schemes or alternative schemes. To this end, the so-called process analysis should be carried out to explore a variety of process plans, to prepare conditions for technical and economic analysis and selection of the best process plans.
The task of process analysis can be summarized as follows: according to the function characteristics, material, shape, dimensional accuracy, quality requirements and production batch of forgings, under the conditions of existing or available equipment, devices, tools, energy, inspection means, management level and personnel quality, put forward a variety of available process schemes.
In process analysis, the following questions must be considered and answered:
1. Can meet the function of forging;
2. Can meet the technical conditions and quality standards of drawings;
3. Whether the forging structure is reasonable and there is no excess dressing;
4. Whether the processing allowance can be reduced;
5. Whether the deformation force or deformation function can be reduced;
6. Whether the metal streamline meets the requirements;
7. There are no omissions in the process of ensuring quality;
8. Whether the processes and working steps have been reduced;
9. Whether the material utilization is sufficient, whether it is possible to forge with other forgings, more than one mold or more than one blank;
10. Have you considered such advanced processes as cold forging, precision forging, rotary forging, rolling, partial forging, sectional forging, combined forging and forging welding?
