Spherical-tipped locators and clamps are often used for the restraint of castings during machining. For structurally rigid castings, contact region deformation and micro-slippage are the predominant modes of workpiece displacement. In turn contact region deformation and micro-slippage are heavily influenced by contact region loading. Maximum loading magnitude has been shown to be a good indicator of workpiece displacement. This paper presents an algorithm which uses the min-max loading criteria as a basis for determining the optimal layout of locators and clamps as well as clamp actuation intensities. The experimentation used for model validation is also discussed along with experimental results.
