What is cylindricality for automotive engines? An explanation of the basics!

Video materials useful for quality control of engine parts.

In the design and manufacturing of automobile engines, the precision of parts is a crucial factor that affects performance and reliability. Particularly for parts with cylindrical shapes inside the engine (such as cylinders and pistons), accurate management of cylindricity is required. If cylindricity is not properly managed, it can lead to increased friction between parts, decreased sealing capability, the occurrence of abnormal noises, and ultimately result in reduced engine performance or failure. This video explains the basics of "cylindricity," which is a type of geometric tolerance. 【Application Scenarios】 - Design and manufacturing of engine parts - Education in quality control departments - Training for engineers 【Benefits of Implementation】 - Deepening understanding of cylindricity and improving quality in design and manufacturing - Enhancing drawing interpretation skills - Early detection of issues in quality control
