What does FM E A mean in quality management?

FMEA is a potential failure mode and effect analysis, if the automotive industry is a must, this is to list all the problems that you can think of in the production process, and then take preventive measures.

Let's put it simply, for example, drill two holes on the iron plate, the hole is large, the hole is small, the drill is more, the drill is less, and forget to drill, if these happen, how to prevent it.

This link is the fmea link in the library, if you are interested, you can take a look.

Analysis of potential failure modes and consequences. A structured and specialized process that systematically and comprehensively identifies and documents potential problems and shortcomings in the design and process process, and makes changes or takes other corrective measures to prevent failures from occurring. It evaluates and analyzes the various possible risks with a view to eliminating them or reducing them to an acceptable level on the basis of prior art.

FMEA is actually a set of serialized activities, the process of which includes: identifying potential failure modes in the product process; According to the corresponding evaluation system, the risk quantification assessment of the identified potential failure modes is carried out; List the cause mechanism of the failure and look for preventive or improvement measures.

f: magnitude of force; m: the mass of the object; A: Acceleration.

1. F=ma is the expression of Newton's second law of motion.

2. The magnitude of the acceleration of the object is proportional to the force, inversely proportional to the mass of the object, and proportional to the reciprocal of the mass of the object; The direction of acceleration is the same as that of the applied force.

3. This law was proposed by Isaac Newton in his book "Mathematical Principles of Natural Philosophy" in 1687.

4. Newton's second law of motion and the first.

The first and third laws together constitute Newton's laws of motion, which expound the basic laws of motion in classical mechanics.

5. Learn physics and strive to achieve "five skills".

Expression: Be able to memorize and correctly describe the content of concepts and laws.

Expression: Clarify the expression formula of concepts and laws and the physical meaning of each symbol in the formula.

Understand: Be able to grasp the scope of application and conditions of use of formulas.

Deformed: The formula will be correctly deformed and the meaning of the deformation will be understood.

Application: Simple judgments, reasoning and calculations using concepts and formulas.

f: The force exerted.

m: is the mass of the particle.

a: is the instantaneous acceleration of a particle at a certain moment.

Newton's second law.

is the law of instantaneous action of force. Force and acceleration are generated, changed and dissipated at the same time.

f=ma is a vector equation, the application should specify the positive direction, all the force or acceleration with the positive direction is taken positive value, vice versa, generally take the direction of acceleration in the direction of the opposite direction.

f is the magnitude of the force, m is the mass, and a is the acceleration.

I'm too bad at physics, is there any good way to learn physics well?

Put aside distracting thoughts, think in life, empty your inherent concepts, empty learning, you are also a scholar.

f refers to the force given to the acceleration of the object, m refers to the mass of the accelerated object, and a is the acceleration caused by the action of the f force!

Physics is mainly the use of those formulas, memorize them, do more exercises, and have no skills. These are only suitable for test-oriented education, that is, the method of exams!

f is and the external force, m is the mass of the object, and a is the acceleration.

You should still be in the first year of high school, work hard, there is no shortcut to study.

f refers to the combined external force, m refers to the mass, and a refers to the acceleration.

Corrective action request, generally through the ISO9000 system documents should have this content, should include CA (corrective action) and PA (preventive action).

Corrective action request is generally available in the ISO9000 system document. CA (corrective action) and PA (preventive action) should be included.

First, quality management refers to the determination of quality policies, objectives and responsibilities, and through the quality planning, quality control, quality assurance and quality improvement in the quality system to achieve all the activities of all management functions.

Second, there are three main reasons for the transition from statistical quality management to total quality management:

1. It is the product of production and the development of science and technology.

2. With the deepening and development of the inherent contradictions of capitalism, with the improvement of workers' cultural knowledge and technical level, and the rise of the trade union movement, etc., in order to alleviate the increasingly acute class contradictions, the attitude and management methods of capitalists towards workers have also undergone new changes, and the bourgeois management theory has made new developments, and the concepts and theories of behavioral science have been introduced into management science, and have entered the stage of "modern management". “

3. Under the fierce competition in the capitalist market, in order to protect their own interests, the majority of consumers buy products of reliable quality, cheap and high-quality products, resist the irresponsible advertising warfare of the capitalists and the slippery goods of promotion, set up various consumer organizations, and there is a movement to "protect the interests of consumers", forcing enterprises to formulate laws to stop enterprises from producing and selling inferior products of poor quality, affecting safety, and endangering health, and to require enterprises to bear legal responsibility and economic responsibility for the quality of products provided.

This is not part of the quality management system, it should be the environmental management manual.

It may be written incorrectly, quality management system QMS

A brochure of the Environmental Management Handbook!

Meaning: the production process of the product, that is, the organization, equipment, operating methods, materials, environment.

Misunderstandings of quality management.

1. One-sided reliance on post-event checks.

The phenomenon of one-sided dependence on post-event checks is widespread, the quality department is only responsible for inspection, regardless of other processes of the quality management system, and at the same time, there is no other department to assume the responsibility of maintaining the quality management system, and the quality of the product all depends on the inspection.

2. Ignoring scientific measures and methods.

The most important manifestation of quality management ignoring scientific measures and methods is: relying entirely on personal experience and preferences, taking human factors as the leading, and there is greater subjective arbitrariness in management behavior, and putting aside the documented quality management system, and not paying attention to the scientificity and rationality of quality management measures and methods.

3. Do not pay attention to the construction and improvement of the quality management system.

One-sided emphasis on the personal improvement of employees does not pay attention to the construction and improvement of the quality management system, ignores the impact of the system environment on personal awareness and ability, and does not realize the complementary relationship between the two.

4. Only treat the symptoms of bad quality phenomena but not the root cause.

Treating the symptoms but not the root cause of bad quality is like treating environmental pollution, only cleaning up pollutants without blocking the source of pollution, and the result is an endless cycle of being busy with pollution, cleaning up, and re-polluting.

The production process of the product, i.e., the organization, equipment, operating methods, materials, and environment.

For example, raw materials, mechanical equipment, and operation methods (metod), the first letter of English is m

The SDCA cycle – the purpose of standardization maintenance is to standardize and stabilize existing processes.

S is the standard (standard), that is, the enterprise to improve the quality of the product to prepare a variety of quality system documents;

D is the implementation (DO), that is, the implementation of the quality system document;

c is the inspection (check), that is, the content review of the quality system and various inspections;

A is to summarize (action), that is, through the review of the quality system, to make corresponding disposal.

The continuous SDCA cycle will ensure the effective operation of the quality system to achieve the expected quality objectivesPDCA and SDCA are the two major wheels for enterprises to improve their management level. PDCA is the driving force for the continuous improvement of enterprise management level, and SDCA is the driving force to prevent the decline of enterprise management level. Without standardization, it is impossible for enterprises to maintain a high level of management.
