Meaning
Adherence to the specified procedures for determining the positioning accuracy and repeatability of numerically controlled machine axes. Achieving iso 230 2 compliance requires a series of bidirectional measurements at multiple points along each axis of motion.
Tolerance Verification
Measurement data provides the statistical foundation for the performance claims made by the builder. When a machine reaches iso 230 2 compliance, the owner has a clear understanding of the minimum feature size the tool can reliably produce. This verification is a prerequisite for high precision aerospace or medical manufacturing contracts.
Measurement Protocol
Technicians use laser interferometers to capture the actual position of the carriage versus the commanded position. Because iso 230 2 compliance involves repeated cycles, it accounts for the backlash and hysteresis inherent in the mechanical drive system. The result is a mean positioning error and a standard deviation that defines the capability of the axis.
Production Audit
Regular retesting ensures that the machine has not drifted out of specification due to wear or structural settling. Maintaining iso 230 2 compliance provides a quality assurance check for the entire maintenance program and the long term stability of the facility. If the results decline over time, it indicates a need for mechanical adjustment or component replacement before scrap rates increase or the process capability falls below the required threshold for critical parts.
