Multiaxis Kinematic Error Compensation Mapping Protocols after Transit
Post-transit multi-axis kinematic re-mapping corrects structural settling and shock displacement to restore five-axis spatial accuracy to sub-ten-micron limits.
Heidenhain KinematicsOpt
Meaning
Multi-axis machining accuracy relies on the precise alignment of the rotary axes of a computer numerical control system. The integration of Heidenhain KinematicsOpt offers a structured software utility that measures and compensates for geometric errors in the machine tool. By using a touch probe and a high-precision calibration sphere, the software automatically captures the actual position of each rotary axis.
The resulting correction values are stored directly in the control system kinematics table to maintain path accuracy.
Calibration Sequence
The measurement routine executes by positioning the calibration sphere at a known location on the machine table. The touch probe then measures the sphere from multiple angular positions of the rotary axis. This sequence calculates the exact center of rotation for each axis, identifying deviation from the nominal coordinate system.
These measurements run without operator intervention, reducing setup time and human error.
Error Compensation
Thermal drift and mechanical wear can displace the rotary axis center over time, leading to dimensional errors in finished parts. By applying the calculated correction values, Heidenhain KinematicsOpt dynamically adjusts the coordinate transformation of the control system during machining. This ensures that the tool center point remains aligned with the programmed path regardless of tilt and rotation.
Regular calibration runs counteract seasonal temperature changes in the workshop.
Accuracy Maintenance
Operators use this system before starting high-precision runs to verify alignment. This step protects critical components from tolerance stack-up.
