1. as long as the defects are caused by the processes in which the actual operation workers play a leading role, the controllable measures to prevent the defects in the sheet metal processing factory are:

(1) Improve the quality awareness, culture and education of "serving customers" and gradually improve the quality responsibility system;

(2) compile and establish a detailed operation process-improve process learning and training, and grant the actual operation certificate;

(3) to improve the "three inspections" work, appropriately increase the frequency of inspections (including self-correction and self-examination);

2. Important control measures are:

(1) improve the level of equipment maintenance management and maintenance, test the key accuracy and characteristics of new items of instruments on time, establish a daily maintenance management system for key positions of mechanical equipment, and control equipment process quality standards;

(2) adopt the first sample inspection management system to review the control amount of the accurate positioning or quantitative device for flexible sheet metal processing (such as the one-time precision level compensation for BG after the CNC shearing machine);

(3) use the processing center as much as possible, reduce the use of actual operation reliability of employees;

(4) according to the establishment of the theme activities of production, processing and maintenance participated by employees of the whole system, TPM management system management shall be slowly established to give full play to the characteristics of mechanical equipment.

3. process methods include the distribution of process flow, the connection between processes, the selection of process production and processing methods (such as the selection of ecological environment specifications for production and processing, the selection of process weapons and equipment configuration, and the selection of basic process parameters), and the preparation of process production and processing guidance documents (such as process flow cards, safety operation procedures for processing centers, operation procedures, process quality inspection tables, etc.).

Process damage to process quality is important from three aspects:

one is to formulate production and processing methods, and select the accuracy and rationality of the basic process parameters and process weapons and equipment of sheet metal processing cabinets.

The second is to implement the process method;

The third is the implementation of inter-enterprise control technology.
