Unidirectional Positioning Accuracy
Unidirectional positioning accuracy is one of the key parameters in evaluating the performance of a rotary positioning platform. It pertains to the platform's positioning accuracy in a single direction. This concept is measured by rotating from the starting position to the end position, selecting multiple data points along the rotational circumference. High unidirectional positioning accuracy impacts the platform's precision in single-direction tasks such as precise machining, engraving, and cutting. Detailed measurement and analysis of unidirectional positioning accuracy ensure that the platform meets the required precision standards, guaranteeing product quality and efficiency in related applications.

Unidirectional System Positioning Error Unidirectional system positioning error refers to the accuracy of the rotary positioning system in a single direction, considering the error produced during the rotation from the starting position to the end position. When designing and manufacturing rotary positioning systems, it is essential to consider these factors, optimize the design and production processes to minimize unidirectional system positioning errors, and ensure the system meets the expected positioning accuracy requirements during operation. Unidirectional Repeatability Accuracy Unidirectional repeatability accuracy refers to the ability of the rotary positioning system to consistently return to the same position in a single direction over multiple positioning operations. This metric measures the system's performance in maintaining accuracy in a specific direction, crucial for applications requiring high consistency and precision. |

Bidirectional Positioning Accuracy
Bidirectional positioning accuracy is a key indicator of the rotary positioning platform's positioning precision, measuring the consistency of the platform's positioning in both directions. It evaluates the platform's accuracy in rotating from the starting position to the end position and then returning from the end position back to the starting position. This ensures the platform can accurately and stably rotate and position in both directions.

Bidirectional System Positioning Error Bidirectional system positioning error refers to the accuracy of the rotary positioning system in both directions, assessing the positioning precision from the starting position to the end position and then returning to the starting position. Errors may arise from various factors, including the mechanical structure's precision, the drive system's performance, and the control system's accuracy. Average Bidirectional System Positioning Error Range The average bidirectional system positioning error range indicates the mean value of positioning accuracy in both directions, typically expressed as a range encompassing maximum and minimum positioning errors. This range is calculated based on a series of measurements, covering all possible scenarios from the system's maximum to minimum positions. Bidirectional Repeatability Accuracy Bidirectional repeatability accuracy measures the rotary positioning system's ability to return to the same position in both directions consistently over multiple operations. This metric is essential for ensuring the system's reliability and precision in applications requiring accurate bidirectional positioning. |

Backlash
Backlash refers to the gap or play within the rotary positioning system due to the mechanical structure or material properties. This gap allows rotary components to move slightly when changing direction without immediately following the new direction. The presence of backlash causes a delay or lag when the rotary positioning system changes direction until the system fully reacts and follows the new direction.
Average Backlash
Average backlash, also known as the mean backlash, indicates the average value of all axial backlashes within the rotary positioning system. This metric is calculated by measuring multiple backlash values and averaging them, serving as an indicator of the overall backlash level of the rotary positioning system. It helps evaluate the system's performance and precision.
