  CMM Calibration for 2-Dimensional Motion TablesA Key to High-Quality Precision Positioning In precision manufacturing, rotary positioning tables are extensively used in machine tools, automation equipment, and precision machining processes. The accuracy of a two-dimensional (2D) motion table significantly impacts overall production quality and repeatability.Traditionally, the industry relies heavily on laser measurement systems for calibration. However, in specific high-precision applications, Coordinate Measuring Machines (CMM) offer a more detailed and visual inspection method.  What is a CMM, and why use it? A CMM (Coordinate Measuring Machine) uses contact probes or optical sensors to measure the geometric shape and dimensions of a component. It accurately captures X, Y, and Z coordinate data, effectively measuring flatness, parallelism, hole positioning, depth differences, and other critical geometric features.  Why do we use CMM in addition to laser inspection？ Laser inspection provides rapid and non-contact measurements suitable for quickly detecting overall contour deviations. However, when it comes to pinpointing subtle deviations in specific positions during 2D rotational movement, especially in parallelism or perpendicularity, laser methods alone may not provide sufficient detail.In these cases, the CMM offers another highly effective solution. With its touch probe system, it precisely measures individual coordinate points, capturing detailed data that laser methods might overlook, enabling comprehensive verification of accuracy throughout table movement. Herbao Machinery’s Rotary Table CMM Calibration Procedure Step 1: Equipment Setup and Establishing Reference PointsThe rotary positioning table is firmly mounted on the CMM’s measuring table. Reference points are established to ensure consistent and accurate subsequent measurements.Step 2: Probe Positioning and Initial CalibrationA highly precise measuring probe locates and records the established reference points on the table’s surface, generating an accurate baseline data model.Step 3: Sequential Angle MeasurementThe table is incrementally rotated, typically by 15 degrees per step. After each rotation, the probe measures again, comparing the targeted angle against actual measurement data to verify rotational positioning accuracy.Step 4: Real-time Data AnalysisMeasurement data is instantly relayed to the computer, where software analyzes precision, ensuring parameters such as flatness, perpendicularity, and concentricity remain within permissible tolerances.Step 5: Comprehensive Data ReportingUpon completing all angle measurements, the CMM generates a detailed inspection report, which serves as a key reference for quality control and analysis, ensuring that the rotary positioning tables consistently meet the highest standards.  Real-World Applications The accuracy of two-dimensional motion tables is critical in industries such as high-precision component manufacturing, PCB drilling, semiconductor packaging, and medical device production. For instance, automated alignment and bonding systems operating without stringent calibration may result in slight inaccuracies, significantly increasing production line defect rates.  Conclusion  The introduction of CMM measurement technology not only enhances the reliability of rotary positioning tables but has become a crucial verification method in the precision machining industry. Herbao Machinery employs this technology to effectively ensure equipment quality, providing industry users with increasingly precise and stable solutions.Video Demonstration  Herbao Machinery continues to pursue technological innovation, providing customers with professional and reliable solutions.For technical inquiries or further information, please contact us! https://www.herbao.com.tw/en/hot_515084.html Knowledge Sharing #7 - Rotary Positioning Table Calibration: CMM as an Alternative to Laser Inspection 2025-05-16 2026-05-16

Industrial Automation Core

 

Rotary Motion and Servo Control

 

 

With rapid technological advancements, modern manufacturing demands precise motion control. Rotary motion and servo control are widely applied in various industrial automation systems, including automated production lines, robotic arms, and precision machining equipment. Two-dimensional motion modules typically involve planar motion control, while three-dimensional motion modules require spatial motion operations. The design and implementation of these modules necessitate a comprehensive understanding of rotary mechanisms and servo motors to achieve high-precision and high-stability motion control.

This article explores the application of rotary motion and servo control in two-dimensional and three-dimensional motion modules, revealing their significance and application prospects in modern industry through theoretical and practical analysis.

 

Rotary Motion

Rotary motion refers to movement around a fixed axis, extensively used in various mechanical devices. In industrial applications, the precision and stability of rotary motion are critical for product quality and machining outcomes. Rotary motion typically relies on the collaborative efforts of speed reducers and servo motors.

Servo Control

Servo control is an automatic control system used for precise control of mechanical equipment's position, speed, and acceleration. A servo control system consists of a servo drive, a servo motor, and a controller. The servo drive receives commands from the controller, drives the servo motor for precise movement, and adjusts motion parameters in real-time through a feedback system, achieving high-precision control.

 

Fundamental Principles of Rotary Mechanisms and Servo Motors

A rotary mechanism is a mechanical transmission device used to reduce the motor's speed and increase its torque output. In rotary motion control, speed reducers can effectively enhance the system's operational stability and precision. The selection process must consider factors such as transmission ratio, load capacity, inertia, and efficiency to meet specific application requirements.

A servo motor is a high-performance motor characterized by quick response, high precision, and high stability. Selection should be based on application requirements, considering parameters such as power, speed, torque, and control precision to achieve the desired movement and accuracy of the rotary mechanism and motion module.

 

 

 

Applications in Two-Dimensional Motion Modules

In two-dimensional motion modules, speed reducers primarily reduce the servo motor's speed and increase its torque output. For instance, in printing machines, speed reducers ensure the smooth operation of printing rollers, preventing mechanical vibrations and printing errors caused by excessive speed. Servo motors drive mechanical components for precise motion, such as in CNC machines, where they accurately control tool position and movement speed, enhancing machining precision and efficiency.

 

Applications in Three-Dimensional Motion Modules

In three-dimensional motion modules, speed reducers not only need to reduce speed and increase torque but also ensure the synchronization of multi-axis linkage. For example, in robotic arms, speed reducers ensure coordinated movement of joints, enhancing the flexibility and precision of the robotic arm's motion. Servo motors drive multiple axes for complex spatial movements, such as in 3D printers, where they precisely control the movement path of the print head, ensuring high precision and quality of the printed products.

 

 

 

The application of rotary motion and servo control technology in modern industry is becoming increasingly widespread. Their significant impact on production efficiency and product quality is evident in two-dimensional and three-dimensional motion modules. The performance and selection of these components affect the overall system's operational efficiency. By deeply understanding the technical principles and application examples, we can better design and implement various industrial automation systems to meet the demands of modern manufacturing.
