Abstract: Total restraint analysis is used to evaluate the ability of a machining fixture to restrain workpiece motion. Thus far models have been limited to point contact and frictionless planar contact. ...

Abstract: 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 ...

Abstract: The geometric variability of locators within a machining fixture is a known source of datum establishment error and machined feature geometric error. A locator tolerance is used to specify the ...

Abstract: Spherical-tipped locators and clamps are often used for the restraint of workpieces during machining. For structurally rigid fixtures and workpieces, contact region deformation, slip, and lift-off ...

Abstract: Workpiece deformation during machining is a significant source of machined feature geometric error. This paper presents a linear, mixed integer programming model for determining the optimal locations ...
