What is engineering competence?

The so-called engineering ability refers to whether high-quality products can be produced uniformly in the production of a certain product, which is an important part of product quality management. The ability of a production process to produce a uniform product is called engineering capability. Use 3 as a numeric value to represent this ability.

Utilize 3 as the reason for the engineering ability value.

If the quality characteristics of a product are normally distributed, the products included in the range of 3 centered on the mean number, so setting the engineering capability value to 3 includes almost all products.

Engineering Capability Index.

The annual construction capacity generally refers to the construction unit can construct millions of square meters of buildings a year, which is its annual construction capacity. It is recommended to count the construction area of the previous year or the specified time.

A construction project can be decomposed into individual projects, unit projects (sub-unit projects), sub-projects (sub-division projects), sub-projects and inspection batches according to the needs of construction project decomposition management.

A unit project has independent design documents, has independent construction conditions and can form an independent use function, but can not independently exert production capacity or engineering benefits after completion of the project (such as the construction of a bridge), is an integral part of a single project.

A single project is a project that has independent design documents in the unit and can independently exert production capacity or project benefits after completion. It is an integral part of the construction project. For example, various production workshops, office buildings, warehouses, etc. in the construction of industrial enterprises; Teaching buildings, libraries, student dormitories, residences, etc. under civil construction.

From the perspective of construction, a single project is an independent system, under the guidance of the overall construction deployment and management objectives of the project, it forms its own project management plan and objectives, and is completed and delivered on schedule in accordance with its investment and quality requirements.

For example, in industrial and civil construction projects, the production workshop, office building, and residential building in a factory construction project can be called a single project; The teaching buildings, canteens, dormitories, etc. in a school construction project can also be called a single project; It is an integral part of infrastructure projects. For example, a contract section of highway engineering that is independently designed, constructed independently, and can be independently handed over and opened to traffic after completion can become a single project.

It refers to how a unit project is divided into divisions, sub-items, and inspection batches, which is a basis for guiding construction and acceptance.

CPK refers to the deviation ( ) between the average value of the process and the standard specification of the product, which is often expressed by the result of the upper deviation of the customer's satisfaction minus the average value and the average value minus the lower limit deviation value, and then divided by three times the sigma result.

cpk=min(tu-,tl) (3*) or cpk=(1-k)*cp, where k= (t 2) is usually unknown for the overall standard deviation ( ) of the distribution of mass characteristic values, so the sample standard deviation (s) should be used instead.

The Process Capability Index indicates the degree to which a process capability meets technical standards (e.g., specifications, tolerances) and is generally denoted as CPK.

The process capability index refers to the degree to which the process capability meets the requirements of product quality standards (specification range, etc.). Also known as the process capacity index, it refers to the actual processing capacity of the process in a controlled state (steady state) for a certain period of time.

It is the inherent ability of the process, or it is the ability of the process to ensure quality. The process referred to here refers to the process of the comprehensive action of five basic quality factors such as operators, machines, raw materials, process methods and production environment, that is, the production process of product quality.

CPK: Abbreviation for Complex Process Capability Index, which is an indicator used by modern enterprises to represent manufacturing capabilities.

A higher CPK value indicates better quality.

cpk=min（（x-lsl/3s），（usl-x/3s））

CPK – Process Capability Index.

CPK = Tolerance - 2 * (Process Center - Specification Center) 6δ

r mean divided by a universal constant).

CPK Application Presentation.

1.The Chinese definition of CPK is: process capability index, which is a quantitative response of a certain engineering or process level, and is also a type of index for engineering evaluation.

ca: Process accuracy. cp: process precision.

3.The relationship between CPK, CA, CP: CPK = CP * 1 - CA), CPK is the neutralization reaction of Ca and CP, Ca reflects the position relationship (central tendency), and CP reacts the dispersion relationship (discrete tendency).

4.When choosing a process station to use CPK for control, the primary factor that should be considered is the cost, as well as the impact of its quality characteristics on the post-production process.

5.There should be at least 20 25 sets of data for the calculation of sampling data to be representative.

6.In addition to collecting sampling data, it is also necessary to know the upper and lower limits of specifications (USL, LSL) for the quality characteristics to calculate the CPK.

7.First of all, the standard deviation ( ) of the sampled data can be automatically calculated by the "stdev" function of excel, and then the specification tolerance (t) and the specification center value (u) can be calculatedSpecification tolerance, upper specification limit, lower specification limit; Specification center value (upper specification + lower specification limit) 2;

8.According to the formula: , calculate the process accuracy: Ca value.

9.According to the formula: cp = , the process precision: cp value is calculated.

10.According to the formula: cpk=cp, the process capability index: cpk value is calculated.

11.Rating criteria of CPK: (The calculated process capability index can be countered accordingly according to this standard).

A++ Grade CPK Premium Cost reduction can be considered.

A+ grade CPK excellent should be maintained.

A CPK has good ability and is stable, but should be promoted to A level as much as possible.

Class B CPK is generally in a general state, and there is a risk of defects if there is a slight variation in the process factors, so it should be upgraded to Class A by using various resources and methods.

Class C CPK Poor The process is defective, and its capability must be improved.

Class D CPK is unacceptable Its capabilities are too poor, and the design process should be redesigned.

CPK refers to the actual processing capacity of the process in a controlled state (steady state) for a certain period of time. It is the inherent ability of the process, or it is the ability of the process to ensure quality.

What does cpk mean.

CPK is also called: Process Capability Index Process Capability Index Process Capability Index refers to the actual processing capacity of the process in a controlled state (steady state) for a certain period of time. It is the inherent ability of the process, or it is the ability of the process to ensure quality.

The process referred to here refers to the process of the comprehensive action of the five basic quality factors (5m) such as the operator, machine, raw materials, process methods and production environment, that is, the production process of product quality. Product quality is the comprehensive performance of the role of various quality factors in the process. As with any production process, product quality is always scattered.

If the process capacity is higher, the dispersion of product quality characteristic values will be smaller; The lower the process capacity, the greater the dispersion of the product quality characteristic values.

One of the quality attributes of the 5 tool "Statistical Process Control (SPC)": the Process Capability Index!

Beginners often judge the ability of a process alone, which is actually incorrect, and should fully identify a process, the variations in the process, and especially the measurement system.

Calculation method of CPK = tolerance zone 6 sigma * (1-offset).

Process energy is an index, which refers to the evaluation of the company's quality management and control capabilities through the analysis of relevant data. Commonly used in the automotive industry. It is one of the five major methods of ISO TS16949 quality management system in the automotive industry.

It is the meaning of the process capability index.

That is, the bidder or applicant must have the minimum qualification requirements of the enterprise.

The proposed project manager (or constructor) is the most suitable for the low qualification level requirements The bidding applicant should have similar engineering experience requirements.

Other bidding conditions required.

Automotive industry standards: key characteristics, process capability index CPK value, and will require normal distribution, full inspection, SPC control, etc., and require measurement system analysis; Important characteristics, process capability index cpk value ;

military products, hungry do not know;

Other manufacturing industries should not be as strict as the automobile industry.

Process capability refers to the actual processing capacity of a process (or process) in a stable state. It is a sign to measure the quality of the process. The analysis of the process capacity of the processing process can enable us to grasp the quality assurance ability of each process in the manufacturing process at any time, so as to provide the necessary information and basis for ensuring and improving product quality.

The fluctuation of product quality is usually expressed by the standard deviation of the probability distribution formed by the process in a stable state, which comprehensively reflects the impact of the six major factors of the process on product quality. Therefore, it is the basis for measuring the size of the process capacity.

Process capability is generally expressed as 6. Obviously6 the greater the fluctuation of the process quality, the lower the process capacity; 6 The smaller, the higher the process capacity. Process capability is an objective property of the process itself.

The process itself doesn't know what the tolerance is", it has nothing to do with the tolerance.

Process capability is reflected by normal fluctuations in the quality of the products he processes. It shows that under certain conditions, the quality fluctuation of the process is not reduced, which is the limit of the fluctuation of the process quality.

When the production process is stable, the quality characteristic values of the vast majority of products obey a normal distribution, or an approximate normal distribution. If 6 is used to measure the process capacity, the process has the ability to produce qualified products.

The process capability can be expressed as: b=6.

Process Ability Judgment:

The larger the value of the process capability index, the smaller the tolerance range of the dispersion of the product relative to the technical standard, and therefore the higher the process capability; The smaller the value of the Process Capability Index, the greater the dispersion of the product relative to the tolerance range, and therefore the lower the process capability. Therefore, the level of capability can be judged from the numerical magnitude of the process capability index. From the point of view of both economic and quality requirements, the process capability index value is not always better, but should be taken within an appropriate range.

Process Capability Determination Method:

1. Direct determination method.

Certain characteristics of the equipment or apparatus used in the process are directly determined to obtain the relevant parameters. For example, the accuracy of the machine tool is checked regularly so that it can maintain good machining performance.

2. Determination of product method.

The product produced by the measurement process is measured and the process capacity is calculated and analyzed based on its variation. The measurement of product quality characteristic value not only obtains the quality of the product itself, but also reflects the change of process quality, and it is often feasible to infer the process quality through product quality. The raw data for calculating the process capability index are obtained by measuring the product.

3. Error analysis method.

By analyzing the errors in operation and management, we can judge whether the process capacity is sufficient. It is often difficult to measure the ability of the operator with instruments and meters, but it is possible to estimate the adequacy of the process capacity by analyzing the type and number of errors.
