Increasing 5-Axis Accuracy

When moldmakers employ five-axis machining, it’s common for geometric errors to occur during the course of normal operation, and these errors can wreak havoc on finished-part quality. There are 13 geometric error types, including A-axis misalignment in the Y-axis direction and perpendicularity error on the C and Y axes. These errors are based on specific parameters, such as the strength, stress, and dimensional deviations of the machine tool’s structure; thermal variations; cutting-force induced errors; and tool wear. Sometimes during operation, machines move and no longer sit level. Calibration can take up to five hours. However, 5-Axis Auto Tuning technology can perform these calibrations automatically in five to 15 minutes.
