How to conduct sampling inspection is a very important issue in promoting quality control. This is because this system determines the level of value delivered to customers. Therefore, this time, we will talk about the relationship between the AQL (Acceptance Quality Limit) of Sampling Inspection and Inspection Level, which is important for quality control, and the points to be observed when deciding the quantity. AQL and Inspection Level in Sampling Inspection In promoting “manufacturing”, it is important to prevent defects from flowing out by building quality ......

Automation is defined as “the deployment of automated processes through technology that monitors and manages production and product shipments,” and is now an irresistible trend for manufacturers. Automation has come so much in the last decade that there’s no industry that hasn’t embraced it. Companies operating in the aerospace, defense, and industrial gas turbine industries are increasingly focusing on viable solutions for fast and accurate inspection of complex parts such as castings in the manufacturing process. How can manufacturers identify casting in......

We were able to inspect the high-precision stands used to transport the cab to other production plants, submit deviation reports to customers in real-time, and make better decisions by estimating the cost of multiple repair measures. Challenge: How to safely transport the cab from one production plant to another in an automated loop fashion? If the cab and chassis are made in separate factories, then the manufacturer uses stands (skids that fix the cab at 4 points) for their transfer. Therefore, in order to hold and maintain the cab safely, both the cab and the stand must ......

Coating is one of the surface treatment technologies in metal processing. By generating a thin film on the surface of the cutting tool, the performance of the original tool material, which is the base material, is enhanced. It is possible to create excellent tools that combine hardness (high sharpness) and toughness (resistance to chipping). Coated tools are widely used as high-precision, high-efficiency cutting tools and stamping dies. This article explains the types of coating films and coated tools used in metalworking sites and their film deposition methods. What Is Co......

In recent years, a labor shortage has become a problem at many manufacturing sites. Due to the declining birthrate and aging population, there is a shortage of human resources in all industries, so more and more companies are hiring foreign technical interns. However, in order to hire interns, they must go through a number of procedures, such as obtaining a status of residence and visa, applying to a management organization, and applying for certification of a technical internship plan. Fortunately, the shortage of manpower for visual inspection at manufacturing sites can be solv......

Welding technology using ultrasonic waves is highly safe because it does not use heat, and is widely applied to food, hygiene, metals, and resin processing.   However, there are several elements to welding, and if you do not know the principle, you may not be able to achieve the desired effect. In this post, we focused on ultrasonic welding and summarized its features, safety, and case studies. 1. What is the mechanism of ultrasonic welding? Simple and fire-free and safe welding principle Ultrasonic welding is a simple mechanism and is very safe because it does not use ......

At automotive parts manufacturing sites, inspections are carried out in a variety of ways, including visual inspections. However, in response to the recent increase in quality requirements, an increasing number of companies are reviewing their existing inspection methods. In this article, we will explain the inspection method of automobile parts again, and then introduce points and examples of inspection. 1. What is automotive parts inspection? First of all, I will explain again the importance of inspection in automobile parts and what kind of inspection methods are ava......

In recent years, the need for precision machining has increased. With the increasing demand for EV components and the advancement of semiconductor processes due to the spread of AI and 5G, cutting sites are facing issues not only with how to “grind” accurately, but also how to “measure” accurately and efficiently. In this article, we talk about the dimensional measurement issues in CNC cutting and the handy probe 3D measuring machine that can perform 3D Dimensional Inspection for anyone, anywhere. CNC Machining Trends and Measurement Needs CNC ma......
