(3) Strengthen the production and inspection personnel to monitor and handle the production process, and supervise and measure the production process; it is to supervise and measure the quality of the production process. We will adjust the monitoring process of the production process to the professional staff of the past. The production personnel and the inspection personnel participate in and work together; the inspection and production guidelines are implemented. The proposed process plan and process rules are recognized by the personnel in the four aspects of skills, production, inspection and quality. The parameters and results will be recognized as “hotâ€. The process of recognizing the process is recognized. The process is evaluated by four parties for the process of the key process; the quality control points, control elements, control methods, inspection results and monitoring personnel are clearly defined. Complete the first “three inspections†and batches. The first batch of determination criteria for parts, on the basis of the process evaluation of the parts and parts produced in batches; the “four-set†criterion is implemented; that is, “fixing process, setting personnel, setting equipment, and controlling the quality of the processâ€; Personnel and inspectors use calculations, histograms, causal maps, etc. The process is analyzed; the quality of the parts and the conditions of production conditions are determined in time. The inspection personnel are given the inspection results of the training results and the qualifications of the production personnel; the recognition of the uniformity of the heating equipment temperature and the temperature control appearance and the temperature control measurement system; Whether the data can be supplied at a fixed point; whether it can have the original certificate and the inspection and production process of the factory can confirm the cycle inspection and inspection results according to the demand; it is clear that the inspectors have the right to prevent all actions that violate the process discipline. The personnel and the inspectors work together to sign the supervision results of the process parameters of the production process and the measurement of the parts; after recognizing the technical procedures, the parts can be transferred to the next road. The production personnel and the inspection personnel together serve as the monitoring process for the production process. It has improved the responsibility and quality of the producers and inspectors; they are the main body of monitoring and control of the production process; they can play an active role in promoting the quality of progressive parts, especially large quantities of continuously produced parts.
(4) Strengthening the implementation of the records of various quality raw data The original records of the process performance of the heat treatment production process, the operation status of the equipment and the degree of conformity of the produced parts are the information sources of ensuring, improving and improving the quality; The main basis for determining the quality of work and quality traceability. In addition to the active paperless recording of new and modified equipment; according to the standard requirements; contact production conditions and characteristics; depicting the process data inspection and production process cycle inspection "Results Table"; "Gas temperature uniformity and measurement system cycle determination table", high-speed steel furnace front metallographic observation table", "original record table of east-west tool production process", "original record table of product parts production process", "quality Forms such as the original record of inspection results, the “receipt of heat treatment and production process†and the “customer satisfaction survey formâ€. Intensive training was carried out on the standard records of various types of personnel; the assessment methods for the standardization of the production process were drafted; The requirements of the standard, the person responsible for the duties, and the various years of storage. The authenticity, standardity, completeness and timeliness of the various parameters of the process can be supervised and measured. The process skills, production handling and quality management personnel randomly view and recognize the conformity of various original results; Non-standard, untimely appearances propose corrective measures to improve; and strictly follow the handling methods, and those who are not careful, non-standard, and untimely in the multiple episodes advocate the transfer of thermal disposal jobs; the original records of various qualityes implemented Real-time processing, providing real and effective data support for the formulation of corrective and preventive measures, quality problem analysis, quality improvement resolution plan and quality system review.
