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

Physical models of anatomical structures can be made using Additive Manufacturing (AM) or Subtractive Manufacturing (SM). The advantage of subtractive techniques over additive ones is the possibility of maintaining the homogeneity and consistency of the processed material, which is extremely importa...
