An evaluation of a linear clamp pre-load model with respect to milling operations

This paper briefly summarizes the formulation and execution of the linear clamp pre-load (LCPL) model. This model is used to compute the minimum clamp pre-loads necessary to keep a workpiece from slipping within a fixturing during machining. This model takes into account all sources of compliance in the fixture-workpiece system as well as gravity and the system of forces exerted during machining. This paper also describes a series of milling experiments that were used to characterize the accuracy of the LCPL model
