Now the machinery industry is developing faster and faster, in many aspects, such as the current sheet metal processing, the details of the processing is also very important. Sheet metal processing equipment is very important, because the equipment performance is excellent, processing efficiency will be greatly improved, which is also a good news for many practitioners. After all, the workmanship and application scenarios of sheet metal processing are extensive. Whether it is daily production or CNC sheet metal processing, the requirements for precision are relatively high; high precision requirements also mean higher requirements for product quality. These basic requirements are important considerations for the current cooperation between sheet metal processing manufacturers and customers. After all, if a manufacturer wants to achieve better development, it is still necessary to start with the basic links.

In sheet metal processing, errors are inevitable. If you want to ensure work efficiency, reduce material waste, and reduce labor costs, you should ensure and improve machining accuracy. The following are specific methods to improve the accuracy of sheet metal processing:

1. original error reduction method: if errors are found in the production process, the main factors affecting the processing errors should be found out first, and then measures should be taken to eliminate or reduce these factors. For example, when machining a part with a shape surface, the focus is on reducing the shape error of the forming tool and the installation error of the tool.

2. Original error compensation method: artificially create a new error to offset the original error in the process system. When the original error is negative, the human error takes a positive value; otherwise, it takes a negative value and tries to make the two equal in size to offset the effect of the original error.

3. original error transfer method: for the original error of the process system, under certain conditions, it can be transferred to the non-sensitive direction of the processing error, or other aspects that do not affect the processing accuracy. For example, when the accuracy of the machine tool cannot meet the processing requirements of the parts, you can start with the process or fixture design to create conditions to transfer the geometric error of the machine tool to the direction that does not affect the processing accuracy.

4. original error averaging method: if the positioning error of special-shaped sheet metal processing is large, the method of differentiating the original error can be adopted. That is, the original error is divided into n groups according to its size, and the error range of each group of blanks is reduced to the original 1/n, and then the processing parameters are adjusted according to the error of each group to ensure the processing accuracy.
