Selection of a workpiece clamping system for computer-aided subtractive manufacturing of geometrically complex medical models

Abstract Physical models of anatomical structures can be made using Additive Manufacturing (AM) or Subtractive (SM). The advantage subtractive techniques over additive ones is the possibility maintaining homogeneity and consistency processed material, which extremely important in case medical devices. Currently, a geometrically complex model even on simple, 3-axis CNC machine tool. However, often semi-finished product must machined at least two clamping configurations. aim work to present method fixing workpiece process production objects example skull bone prostheses. paper discusses use systems for machining such models. It presents prostheses fitted defect with proposed methods workpiece. result are prosthesis. A more was analysed terms accuracy geometry reproduction. research confirmed usefulness preparation structures.
