What if the Sheet Metal Machining is Not Qualified?

With the advancement of technology and the improvement of high-performance equipment, the process of the professional sheet metal fabrication is becoming more and more mature, and it has been widely used in all walks of life.

Whether it is electronic appliances or automobile industry, communication engineering or medical equipment industry are inseparable from the sheet metal machining. However, in actual operation, there is a phenomenon of uneven quality. Here are some improvement measures.

Ⅰ. The operator factors of the sheet metal machining

For the defects caused by the process in which the operator plays a leading role, the controllable measures to prevent the defects are as follows:

1. Strengthen the quality awareness education of "quality first, users first", and establish and improve the quality responsibility system.

2. Write clear and detailed operation procedures - strengthen professional training on procedures and issue operation certificates.

3. Strengthen the "three inspections" work, and appropriately increase the frequency of inspections (including self-inspections).

Ⅱ. The machine factors of the sheet metal machining

1. Strengthen equipment maintenance and maintenance, regularly test the key accuracy and performance items of the equipment, and establish a daily spot inspection system for key parts of the equipment to focus on the equipment at the process quality control points.

2. Adopt the first article inspection system to verify the adjustment of the positioning or quantitative device (such as the one-time positioning accuracy compensation of the back gauge BG of the bending machine).

3. Use CNC machines wherever possible to reduce reliance on sheet metal machining workers for operational reliability.

4. Gradually establish a TPM management system, that is, through the establishment of a production maintenance activity involving the participation of employees in the whole system, to optimize the performance of equipment.

Ⅲ. The sheet metal machining technology

The process method includes the arrangement of the process flow, the connection between processes, the selection of process processing methods (such as the selection of processing environmental conditions, the selection of process equipment configuration, the selection of process parameters) and the preparation of process processing guidance documents (such as process flow cards, machine tool operating procedures, work instructions, process quality analysis table, etc.).

The influence of the sheet metal machining technology on the quality of the process mainly comes from three aspects: one is the correctness and rationality of formulating the processing method, the selected process parameters and process equipment; the second is the seriousness of implementing the process method; the third is the department oversee the execution of the process.
