• Dimensional accuracy refers to the accuracy of the dimensions of a specified part, such as the length, diameter, thickness, and keyway width of the workpiece. This dimensional accuracy is important for the part to be integrated into the machine and operate properly. If the dimensions are incorrect, it can cause the machine to fail. To prevent this, tolerances must be indicated in the drawing so that the dimensional accuracy of the critical parts is available when designing the part. For example, when designing a bearing with an outer diameter of Φ25 axis, it is necessary to indic......

  • The environmental audit is the activity carried out, periodically, by an organization to evaluate the performance of its management for the care of the environment and, in the case of being obliged to comply with a standard, a law or a standard, verify compliance with those requirements. Other activities, with similar purposes and which are also very important for the success of management such as inspections and reviews, are often confused or taken as an environmental audit, without being so. The differences between them go beyond the semantic. In the case of the audit, for e......

  • The expression “burrs” that is commonly used in metal processing sites such as pressing and cutting may not be understood by people who are not involved. Therefore, on this page, we will explain what burr is and why it occurs. We will also introduce the challenges of measuring burr as a quality inspection and how to solve them. What Is Burr? Burr is a metal ledge that occurs on the cut surface in shearing and drilling by pressing. It is also commonly defined as “the outer residue of a geometric shape at the edge of the shape and the residue on the part during......

  • Quality Inspection is an important process to ensure quality by evaluating whether the products of manufactured parts and products conform to the specified values. In particular, inspections of appearance, dimensions, and shape can not only prevent the outflow of defective products by determining whether OK or NG is possible but are also useful for identifying the cause and preventing recurrence by obtaining detailed information on defects and defects and conditions. In addition, in the case of products consisting of multiple parts, it is possible to prevent the outflow of defect......

  • Gears, along with screws and springs, are parts used in many products. There is a wide variety of sizes, shapes, and materials depending on the application. In addition, there are various functions, and it can be used for various purposes by combining gears and gears, as well as shafts and cams. And all gears are made with high precision. However, with increased use, for example, deformation due to wear occurs. Among them, the dimension of “tooth thickness” is important, and it greatly affects not only the operation of the gear but also the strength. Here, the conc......
