Embodiment Construction
[0018] A method for traceability of automobile parts process control quality, characterized in that it comprises the following steps:
[0019] S1. According to the repair records of returning to the factory or the repair shop, find and record the parts with problems, sort the number of times the parts have problems, and select some parts according to the sorting as the first key part group;
[0020] S2. Make statistics on the production costs of the parts with problems, and sort the production costs, and select some parts according to the sorting as the second key parts group;
[0021] S3. Multiply the number of parts with problems and the cost of the parts, and sort them, and select a part of the parts according to the size of the product as the third key part group;
[0022] S4. Take the union of the first key part group, the second key part group and the third key part group to determine the key parts;
[0023] S5. Determine the production equipment and operators for the p...

The invention discloses an automobile part process control quality tracing method, which comprises the following steps of: searching and recording defective parts according to maintenance records of factory return maintenance or maintenance shops, and selecting a first key part group; Counting the production cost of the parts with the problems, sorting the production cost, and selecting a second key part group; Multiplying the number of times that the parts go wrong by the cost of the parts, performing sorting, and selecting one part of the parts as a third key part group; Determining key parts; Recording each group of key parts; Carrying out factory inspection on each group of key parts; And through data statistical analysis, the cause of problems of the part is found out. According to the method, the problem parts forming the parts are found out in a scientific and reasonable mode, the reasons of problems of the parts are found out through a statistical method, the product quality can be effectively improved, and the cost of the tracing process is saved.
Description
technical field [0001] The invention belongs to the technical field of parts processing, and in particular relates to a process control quality tracing method for auto parts. Background technique [0002] In the ISO system, quality traceability is defined as: the ability to trace back the origin, purpose and location of an entity by means of record identification. When appropriate, the organization shall use appropriate methods to identify products throughout the product realization process, identify products with standards or appropriate methods, and prevent mixing or misuse of products of different types, specifications or states. Where traceability requirements are stipulated, the formation process of product quality can be traced through unique identification and records, so as to clarify the source of product raw materials and parts, find out the cause of quality problems, and clarify responsibilities. [0003] In the process of realizing the quality traceability of au...
