Inspection method of quality inspector

One of the basic principles of quality control, one of the main tasks of quality management is to find out the law of fluctuation by collecting and sorting out data, control normal fluctuation to a minimum, and eliminate abnormal fluctuation caused by system reasons.

Comparing the measured quality characteristics with relevant standards, and taking corresponding measures to correct the differences or abnormal phenomena, so that the process is under control, this process is called quality control.

Quality control can be roughly divided into seven steps:

(1) Select the control object;

(2) selecting the quality characteristic value to be monitored;

(3) Determine specifications and standards, and specify quality characteristics in detail;

(4) Choose a monitoring instrument that can accurately measure the characteristic value, or make a self-made test method;

(5) Carry out actual test and record data;

(6) Analyze the reasons for the difference between the actual and the standard;

(7) Take corresponding corrective measures. After taking corresponding corrective measures, the process should still be monitored to keep the process at a new control level.

Once new influencing factors appear, it is necessary to measure the data, analyze the reasons and make corrections, so these seven steps form a closed process called "feedback loop". This has something in common with MAIC of 6Sigma quality breakthrough mode.

In the above seven steps, there are two main points:

(1) quality control system design;

(2) Selection of quality control technology.

Second, when designing a quality control system, it is necessary to make decisions on the process to be controlled, quality inspection points, inspectors, measurement types and quantities. After these decisions are completed, a complete quality control system is formed.

1. Process analysis All quality management work must start from the process itself. Before quality control, it is necessary to analyze the related process of producing products or services. A big process may include many small processes, and these processes are described and decomposed by flow chart analysis to determine the key links that affect the quality of products or services.

2. Determination of quality inspection points After determining each process that needs to be controlled, it is necessary to find the key points that need to be measured or tested in each process. There may be many inspection points in a process, but each inspection will increase the cost of products or services, so the inspection should be carried out in the place where quality problems are most likely to occur.

Typical detection points include:

(1) Inspection of purchased raw materials or services before production. In order to ensure the smooth progress of the production process, we must first ensure the quality of raw materials or services through inspection. Of course, if the supplier has a quality certificate, this inspection can be exempted. In addition, in JIT (just-in-time production), the inspection of purchased parts is not advocated, and it is considered that this process has no added value and is "waste".

(2) Product inspection in the production process: The typical inspection in the production process is before irreversible operation or high value-added operation. Because once these operations are carried out, the quality will be seriously affected and great losses will be caused. For example, ceramics need to be inspected before sintering. Because once sintered, unqualified products can only be discarded or treated as defective products. For example, products need to be inspected before electroplating or painting to avoid defects being covered up. These operations can be checked by the operator himself. The inspection in production can also judge whether the process is controlled. If the inspection results show that the quality fluctuates greatly, measures should be taken to correct it in time.

(3) Inspection of finished products after production. In order to correct the defects of products before they are delivered to customers, it is necessary to inspect the products before they are put into storage or sent.

3. Inspection method Next, it is necessary to determine what type of inspection method should be adopted at each quality control point. Inspection methods are divided into: counting inspection and measurement inspection. Counting test is to test discrete variables such as defect number and unqualified rate; Metrological detection is the measurement of continuous variables such as length, height, weight and strength. In the quality control of production process, what kind of control charts should be considered: the counting control chart of discrete variables and the metering control chart of continuous variables.

4. There are two ways to determine the number of inspection samples: full inspection and sampling inspection. The guiding principle for determining the inspection quantity is to compare the loss caused by unqualified frequency with the inspection cost. Suppose there is a batch of 500 products, the product failure rate is 2%, and the maintenance and compensation cost caused by each unqualified product is 100 yuan. If this batch of products is not inspected, the total loss will be100 *10 =1000 yuan.

If the inspection fee of this batch of products is less than 1000 yuan, it should be fully inspected. Of course, there are other factors to consider besides cost. Products involving personal safety need 100% inspection. While sampling inspection is used for destructive inspection.

5. Inspectors Inspectors can be determined by the principle of combining operators with full-time inspectors. In 6Sigma management, most inspection tasks are usually completed by operators.

Quality control technology Quality control technology includes two categories: sampling inspection and process quality control.

Sampling inspection usually occurs in raw material inspection before production or finished product inspection after production, and whether to accept the batch of raw materials or products is decided according to the quality inspection results of random sampling. Process quality control refers to the inspection of random samples of products in the production process to determine whether the process is produced within the predetermined standards. Sampling inspection is used for purchasing or acceptance, while process quality control is applied to various forms of production processes.

Section 2 Process quality control technology Since shewhart put forward the control chart in 1924, after nearly 80 years of development, process quality control technology has been widely used in quality management, and many new methods have been continuously produced in practice. Such as histogram, correlation diagram, Pareto diagram, control diagram, causal diagram, correlation diagram, system diagram and other "seven new QC tools". Using these methods, we can systematically collect all kinds of data related to products from the ever-changing production process, arrange, process and analyze the data by statistical methods, and then draw various charts to find out the law of quality change and realize quality control. Ishikawa once said that 95% of the quality problems in enterprises can be solved by all employees applying these tools. ISO9000 and 6Sigma quality management theory, which is very popular in recent years, both emphasize the application of these statistical-based quality control technologies. Therefore, in order to truly improve product quality, enterprises from top management to leaders to employees must master quality control technology and apply it to practice.

(1) Histogram The method of using histogram is to mark the discrete state distribution of data on the chart with vertical bars, thus helping people to find the problem area in a narrow range according to the displayed pattern changes, from which they can know the average horizontal deviation of data and judge the overall quality distribution.

(2) histogram drawing method The following example introduces how to draw a histogram.

To produce a ball, the diameter x is required to be 15.0 1.0 mm, and the production process is statistically analyzed by histogram.

1. Collecting data Under the condition that 5M 1E (man, machine, method, measurement and production environment) is completely fixed and standardized, N data are collected from the production process. N should not be less than 50, but better than 100. In this example, the diameters of 50 balls are measured in the table below. Where Li is the maximum value of the data in the ith row and Si is the minimum value of the data in the ith row. Table 5- 1 50 ball samples with diameter.
