Operator factor

For all defects generated by the process in which the operator plays a leading role, the controllable measures to prevent the defects are:

• Strengthen the quality awareness education of “quality first, customer first”, and establish and improve the quality responsibility system;

• Strengthen the quality awareness education of “quality first, customer first”, and establish and improve the quality responsibility system;

• Strengthen the quality awareness education of “quality first, customer first”, and establish and improve the quality responsibility system;

Machine factor

The main control measures are:

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

• (2) The first article inspection system is used to verify the adjustment amount of the positioning or quantitative device (such as the primary positioning accuracy compensation of the BG of the rear windshield material of the bending machine);

• (3) Use CNC machine tools as much as possible to reduce the dependence on the reliability of workers’ operations;

• (4) Gradually establish a TPM management system, that is, through the establishment of a system-wide staff to participate in production and maintenance activities, so that the equipment performance can be optimized.

Sheet metal processing technology

The process method includes the arrangement of the process flow, the connection between the processes, the selection of the process processing means (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 card, machine tool operation procedures, work instructions, process quality analysis table, etc.), the influence of process methods on process quality mainly comes from three aspects: one is the development of processing methods, the correctness and rationality of the selected process parameters and process equipment; the second is the seriousness of implementing the process method; The third is to supervise the implementation of the process between departments.
