THE EVALUATION OF DIMENSIONAL AND SHAPE ACCURACY OF FRICTION PAIR ELEMENTS: BALL-CUP

Niemczewska-Wójcik Magdalena, Krawczyk Marcin, Wójcik Artur
Abstract:
The paper presents the principles and stages of forming a ball (metal head component) and a cup (polymeric acetabular component) constituting an artificial hip joint in the finishing process. The requirements of the standard specification ASTM F2033-12 concerning a method for measuring permissible limits of departure from roundness and roundness tolerance of examined elements were discussed. The obtained measurement results were analyzed and evaluated, on the basis of which conclusions were drawn and directions for further research were indicated.
