您好，歡迎訪問 educationleaves.com。

In this video, we are going to learn about inspection and quality control in manufacturing.

在本視頻中，我們將瞭解製造過程中的檢驗和品質控制。

In a manufacturing plant, inspection and quality control are the most important process in order to make a high-quality product.

在製造工廠，檢驗和品質控制是製造高質量產品的最重要過程。

Inspection and quality control ensures the standard quality by checking the product during manufacturing at different stages.

檢驗和品質控制通過在不同生產階段對產品進行檢查來確保標準品質。

If the product is not able to meet the desired quality, the product will reject and there will no further process on that unit.

如果產品不能達到預期的品質要求，產品將被拒收，該設備將不再進行下一步加工。

It saves unnecessary processing costs on rejected parts.

它可以節省被剔除部件的不必要加工成本。

After manufacturing, the product is required to perform certain functions.

產品製造完成後，需要執行某些功能。

The process of checking whether the product does so or not is called inspection.

檢查產品是否做到這一點的過程稱為檢驗。

Inspection compares the qualities of the product with a standard product during manufacturing.

檢驗將產品的品質與生產過程中的標準產品進行比較。

In other words, inspection is a process of checking the acceptability of a manufactured product.

換句話說，檢驗是一個檢查製成品可接受性的過程。

Inspection separates defective components from the non-defective components so that adequate quality can be maintained.

檢查可將有缺陷的部件從無缺陷的部件中分離出來，從而保證足夠的品質。

Inspection locates defects in process or raw material which otherwise causes problems at the final stage.

檢驗能找出加工過程或原材料中的缺陷，否則就會在最後階段造成問題。

It prevents further working on spoiled semi-finished products.

它可以防止變質的半成品繼續加工。

It helps the product to be more economical.

這有助於提高產品的經濟效益。

Inspection detects the weak position and trouble in the weak position by checking the design.

通過檢查設計，檢測薄弱位置和薄弱位置的故障。

Revolving Process, Patrolling or Floor Inspection 2.

Revolving Inspection In this type of inspection, the inspector walks around the workplace floor and checks machine to machine, samples of the work of various workers and machines.

旋轉檢查 在這種檢查中，檢查員在工作場所的地面上走來走去，逐臺機器檢查，對不同工人和機器的工作進行抽樣檢查。

The revolving inspection helps to find errors during the process and before the final product is ready.

旋轉檢查有助於在加工過程中和最終產品準備就緒之前發現錯誤。

It is more effective and not need to move the product to another department for checking. 2.

這樣做更有效，不需要將產品轉移到其他部門進行檢查。2.

Fixed Inspection Fixed inspection finds defects after the job has been completed.

固定檢查 固定檢查在工作完成後發現缺陷。

Fixed inspection is used when inspection equipment and tools cannot be brought on the workplace.

當無法將檢查設備和工具帶入工作場所時，可採用固定檢查。

In this case, workers brought the sample to a centralized position of the workplace, at the interval to check the quality.

在這種情況下，工人將樣品帶到工作場所的一個集中位置，每隔一段時間檢查一次品質。

Advantages of fixed inspection are the number of inspectors needed is less, and workers and inspectors do not come in contact with each other, thus it eliminates the chance of approving the doubtful products. 3.

固定檢驗的優點是所需的檢驗員人數較少，工人和檢驗員互不接觸，從而消除了準許可疑產品的機會。3.

Key Point Inspection A key point is a stage of production beyond which, it requires an expensive operation, or it may not rework.

關鍵點檢查 關鍵點是生產的一個階段，超過這個階段就需要進行昂貴的操作，否則可能無法返工。

Every product has a key point in its process of manufacturing.

每件產品在生產過程中都有一個關鍵點。

Inspection at key point separates faulty products, and reject them from going to further processing.

在關鍵點上進行檢查，可分離出有問題的產品，並將其剔除，以免進入下一步加工。

Thus avoid unnecessary further expenditure on those poor and substandard products.

這樣，就可以避免不必要的進一步支出，購買那些劣質和不合格的產品。

Final Inspection In the final inspection, the inspector checks the performance, and appearance of the product before delivery.

最終檢驗 在最終檢驗中，檢驗員在交貨前檢查產品的性能和外觀。

These types of checking include destructive and non-destructive testing such as tensile testing, impact testing, fatigue testing, etc.

這些檢查類型包括破壞性和非破壞性測試，如拉伸測試、衝擊測試、疲勞測試等。

The final stage of inspection ensures that the product should pass the X-ray radiography, ultrasonic inspection, etc. 5.  Let's move to quality control.

最後階段的檢驗確保產品應通過 X 射線照相、超音波檢驗等。5.  下面進入品質控制階段。

Quality control in manufacturing is a process through which, a production system ensures that standard product quality is maintained or improved according to customer's needs.

製造業的品質控制是一個過程，通過這個過程，生產系統可確保根據客戶需求保持或提高標準產品質量。

In other words, it incorporates the testing of units, and determines if the product is within the specification for the final production.

換句話說，它包括單元測試，並確定產品是否符合最終生產的規格要求。

The role of testing is to determine there is any need for correction in the process, so that product can meet the customer's desire.

測試的作用是確定是否需要對流程進行修正，從而使產品能夠滿足客戶的需求。

Importance of Quality Control If I explain quality and control separately, quality is a relative term, and it is explained by comparing it with a standard product.

品質控制的重要性 如果把品質和控制分開來解釋，品質是一個相對的術語，通過與標準產品的比較來解釋。

For example, gear used in sugarcane juice extracting machine isn't as correct, finished as gear used in an engine transmission system.

例如，甘蔗榨汁機中使用的齒輪就不像發動機傳動系統中使用的齒輪那樣正確、完好。

So, a component is said to be good quality if the component works well for which it is meant.

是以，如果一個元件能很好地發揮其應有的作用，就可以說它是優質元件。

On the other hand, control is a system for determining, what to inspect, how to inspect, and how often to inspect.

另一方面，控制是一個確定檢查什麼、如何檢查以及檢查頻率的系統。

It also finds out the causes for producing a poor product, and suggests the corrective action.

它還能找出生產不良產品的原因，並提出糾正措施。

An important aspect of quality control is the establishment of well-defined controls.

品質控制的一個重要方面是建立明確的控制措施。

Limiting the chances of error, and reduce the manufacturing cost will generate more profit.

限制出錯機率，降低製造成本，就能創造更多利潤。

Basic Fundamentals of Statistical Quality Control It called Statistical Quality Control if statistical techniques are applied to control the quality or to solve quality control problems.

統計品質控制的基本原理 如果應用統計技術來控制品質或解決品質控制問題，則稱為統計品質控制。

Statistical Quality Control makes inspection less costly and more reliable than other techniques.

與其他技術相比，統計品質控制使檢驗成本更低，可靠性更高。

It controls the quality of outgoing products to conclude whether the quality of each product is as per laid quality standard or not.

它對出廠產品的品質進行控制，以確定每件產品的品質是否符合規定的質量標準。

The SQC technique collects, analyzes the data, and permits more fundamental control over the product quality.

SQC 技術收集和分析數據，並對產品質量進行更基本的控制。

It scientifically fixes the process tolerance.

If we summarize the whole lecture into one line, inspection is important to maintain a certain quality during the manufacturing of a product.

如果把整個講座概括為一句話，那就是在產品生產過程中，檢驗對於保持一定的品質非常重要。

And, quality control is a process by which customer ensures receive product free from defects.

品質控制是客戶確保收到無缺陷產品的過程。
