Meaning
Standardized evaluation procedures for coordinate measuring machines establish the accuracy limits for dimensional measurements of manufactured parts. The iso 10360-2 standard defines the performance tests used to verify that a coordinate measuring machine is operating within its specified maximum permissible error limits. It is a critical quality standard for high-precision injection molders, ensuring that the dimensional data used to buy or reject parts is accurate and traceable to national standards.
Metrology Setup
Multi-point testing involves measuring a series of five different lengths, each measured three times in seven different positions within the machine’s volume. This comprehensive testing assesses the machine’s geometric and volumetric accuracy, providing a realistic measure of its performance under actual measuring conditions. It ensures that the machine can accurately measure complex molded parts with tight tolerances.
Gage R&R
Calibration certificates provided by this standard are essential for establishing the measurement uncertainty of the inspection process. If the measuring machine has not been calibrated to this standard, the dimensional data it produces may not be accepted by the buyer, leading to disputes over part quality. This calibration is particularly important for medical device molders who must validate their measurement processes.
Process Adaptation
Molders use these calibrated machines to perform first article inspections and ongoing statistical process control during high-volume production runs. Ensuring that the coordinate measuring machine is calibrated to this standard minimizes the risk of accepting out-of-tolerance parts or rejecting good ones, which reduces waste and improves the efficiency of the molding run. This is a key requirement for maintaining high-quality standards in automotive and aerospace molding, where even minor dimensional errors can lead to assembly failures or performance issues in the field.
Measuring instruments that comply with this standard provide the necessary assurance for high-precision manufacturing operations.
