Manufacturing quality control technology
There are seven new and old methods of QC, "SPC, MSA, APQP, PPAP, FMEA (five core tools)", continuous improvement of PDCA, analysis and solution of system problems, 8D, 4M 1E, five whys, quality cost control and so on.

Seven skills of old QC:

1) lookup table

How to make a list

● Types and contents of the list

Examples of using lookup tables

2) Fishbone diagram

● fishbone diagram method

● Application of two fishbone diagrams

● Good fishbone diagram and bad fishbone diagram.

3) Plato

● Plato's practice

Application of Plato's analysis

● Examples used by Plato

4) Layer diagram

● Importance of stratification (ST classification)

● Layered method

● Examples of using hierarchical methods

5) Histogram

The purpose of using histogram.

Low histogram view and usage.

6) scatter plot

The significance of scatter plot.

Practice of scatter diagram.

● Use scatter plot to review the problems on site.

7) Control chart-a tool to monitor whether the variation and fluctuation of the process are stable.

● Principle and classification of control chart

● Explain and judge the control chart.

Five core tools, namely FMEA (Potential Failure Mode and Consequence Analysis), APQP (Product Advance Planning), PPAP (Product Approval Procedure), MSA (Measurement System Analysis) and SPC (Statistical Process Analysis); FMEA was first used in American aerospace industry, and advanced management ideas and models were widely used for reference by various manufacturing industries. Now, due to the impact of the financial turmoil in the United States, enterprises have begun to lay off employees (slim down) to preserve their strength and make great achievements in the coming year; At this time, enterprises need to further optimize the management of factories and use management tools to predict and control the defective rate of products in order to reduce costs. In order to better serve customers, enterprises urgently need to improve their management level to meet the requirements of international quality management standards. Starting from 2009, this will be a world of high quality/brand.

Seven skills of new QC:

1. Correlation diagram: Find out the results of the interweaving problem of complex factors, so as to find out the corresponding solutions. Function: It is suitable for analyzing and sorting out the problems intertwined with various complex factors. After many revisions and drawings, the key to solving the problem can be clearly defined and the key points can be accurately grasped.

2. System diagram: The purpose to be achieved and the measures or methods to be taken are systematically developed step by step, so as to clarify the focus of the problem and find the best means or methods.

3.KJ method: unify the language data collected from the chaotic state according to their mutual affinity, and clarify the problems to be solved.

4. Brainstorming method: It is a collective creative thinking method that uses meetings to guide everyone attending the meeting to speak freely around a central topic, stimulate inspiration, set off ideological storms in their own minds, and freely express independent opinions without scruple.

5. Matrix diagram: it is a method to make the problem clear step by step by using multi-dimensional thinking, that is, to express the relationship between various factors in the form of matrix in mathematics, to explore the problem from it, and to get the idea of solving the problem.

6. Process decision-making program diagram method: it is a method to predict possible obstacles in advance in the planning stage or system design stage, so as to design a series of countermeasures and measures to achieve ideal results with the greatest possibility.

7.PERT is a directed line chart. According to its time sequence and affiliation, it represents all the work necessary to advance the plan in the form of a network.

SPC training

I. Basic concepts

1, variation: general variation, special variation and total variation and their characteristics.

2. Normal distribution: normal distribution function, standard normal distribution curve and its three elements.

3. Data: measurement data and counting data.

4. Check the chart

Secondly, it introduces one of the most commonly used measurement control charts-X-R chart.

Third, introduce other control charts.

FMEA training

I. Purpose

Two. range

Three. term

Four. accountability

Seven. appendix

APQP training and PPAP training

First, the basic principles of product quality planning

Two. Planning and determining projects

Three. Product design and development

Four. Process design and development

Verb (abbreviation for verb) product and process verification

Feedback, evaluation and corrective measures of intransitive verbs

MSA training

1, the purpose, scope of application and terminology of MSA;

2. Statistical characteristics of the measurement system;

3. Classification of measurement system variation;

4. Definition and graphic expression of measurement system change (bias, repeatability, reproducibility, stability and linearity);

5. Preparation of measurement system research;

6. Biased analytical methods and criteria;

7. Analytical methods and standards for repeatability and reproducibility;

8. Analysis methods and standards of stability;

9. Linear analysis methods and standards;
