How to divide QC, IQC, IPQC, QA in CNC workshop?

QC: Quality Control, the general term for quality control, product quality inspection, analysis, improvement and non-conforming product control related personnel after quality problems are found. Generally include:

IQC (Incoming Quality Control, Incoming Quality Control)

IPQC (In-Process Quality Control, process inspection)

FQC (Final Quality Control, finished product inspection)

OQC (Out-going Quality Control, shipping inspection)

QC focuses on the product, not the system (system). This is the main difference between it and QA. The purpose is the same as that of QA, which is to "meet or exceed customer requirements."

QA: Quality Assurance, quality assurance, through the establishment and maintenance of a quality management system to ensure that there is no problem with product quality. Generally include system engineers, SQE (Supplier Quality Engineer: supplier quality engineer), CTS (customer technical service personnel), 6sigma engineers, calibration and management personnel of measuring instruments.

QA not only needs to know where the problems are, but also how to formulate solutions to these problems, and how to prevent them in the future. QC needs to know that if there is a problem, it should be controlled, but it does not necessarily need to know why it should be controlled in this way.

To use an inappropriate analogy, QC is a policeman and QA is a judge. QC only needs to catch anyone who violates the law. It cannot prevent others from committing crimes and convict them. The judge is to make laws to prevent crimes and pronounce judgments in accordance with the law. Disposal result.

In summary, QC mainly focuses on quality inspection activities after the fact. By default, errors are allowed, and errors are expected to be discovered and selected. QA is mainly an advance quality assurance activity, focusing on prevention, hoping to reduce the probability of errors.

QC is the operation technology and activities taken to make the product meet the quality requirements. It includes inspection, correction and feedback. For example, after QC conducts inspection and finds defective products, they will be eliminated, and then the bad information will be fed back to the relevant departments to take improvement measures. Therefore, the scope of QC's control is mainly within the factory. Its purpose is to prevent the input, transfer, and delivery of unqualified products, to ensure that products meet quality requirements and only qualified products can be delivered to customers.

QA is to provide trust to meet customer requirements, even if the customer is convinced that the product you provide can meet his requirements, it is necessary to review customer requirements from the beginning of market research and later, product development, order and material procurement, incoming inspection, and production process Evidence is left at each stage of control, shipment, and after-sales service to confirm that every step of the factory's activities is carried out according to customer requirements.

The purpose of QA is not to ensure product quality, it is the task of QC to ensure product quality. QA is mainly to provide assurance. Therefore, it is necessary to manage the entire process from understanding customer requirements to after-sales service. This requires companies to establish a quality control system, formulate corresponding documents to regulate the activities of each process and leave evidence of the implementation of the activities in order to provide trust. This kind of trust can be divided into two types: internal and external: the external, even if the customer is at ease, believe that the factory produces and deliver products according to its requirements; the internal is to let the factory owner rest assured, because the boss is the first person responsible for product quality, and the product has quality accidents. He has to take full responsibility. This is also the main requirement for countries to formulate product quality laws to encourage companies to really pay attention to quality. Therefore, in order to avoid responsibility for quality, the boss must standardize various activities with documents and leave evidence. However, it is impossible for the boss to know whether the internal personnel of the factory operate according to the document requirements. This requires QA to conduct audits on his behalf to understand whether the document requirements are complied with, so that the boss can believe that the various activities of the factory are carried out in accordance with the document. Reassured him.

Therefore, the main difference between QC and QA is: the former is to ensure that the product quality meets the regulations, and the latter is to establish a system and ensure that the system operates as required to provide internal and external trust. At the same time, QC and QA have the same points: that is, both QC and QA must be verified. For example, QC testing products according to standards is to verify whether the product meets the specified requirements, and QA's internal audit is to verify whether the system operation meets the standard requirements. Cargo audit and reliability testing are to verify whether the product has performed various activities in accordance with the regulations and whether it can meet the specified requirements, so as to ensure that the products delivered by the factory are qualified and comply with relevant regulations.

The most important responsibility of QC is to monitor finished products (mainly including Raw material, in-process goods, finish goods, and in-process audit), focusing on detecting defects through Sample Inspection.

IPQC responsibilities:

1. Inspect the products in the production process and keep records

2. Fill in the inspection report according to the inspection record
