Artificial Joint Measurement (CME)
- Measurement Challenges
  
  Artificial joints are used to replace damaged human joints and restore joint movement functionality. For example, a total hip joint replacement includes four components: the acetabular cup, liner, femoral head, and femoral stem. The acetabular cup and femoral head form the joint surface, while the liner covers the inside of the acetabular cup and contacts the femoral head to reduce friction and wear. The dimensional accuracy of the mating parts is critical, as it affects the patient's experience and joint longevity.
- Solutions
  
  The coordinate measuring machine (CMM) performs full-size measurement of artificial joint components, such as the groove or profile of the acetabular cup, acetabular depth and inner diameter, the outer shape of the liner (length, width, angle), the diameter or roundness of the femoral head, and the contour of the femoral stem.
