In the field of industrial automation, “SCADA” and “PLC” are two frequently mentioned terms, yet many people still struggle to distinguish between them. Some may ask: “Who is responsible for monitoring? Who is responsible for control?” Today, let us clarify this in a straightforward manner. What is SCADA? SCADA (Supervisory Control and Data Acquisition) is … Read more
1. Application Background and Measurement Objectives In industrial manufacturing, cylindrical runout is a key indicator for assessing the machining accuracy of shaft-like parts (such as motor shafts, hydraulic cylinder piston rods, and precision bearing inner rings). It refers to the radial deviation of each point on the surface of a cylinder during rotation relative to … Read more
