# Fixturing analysis methods for calculating the contact load distribution and the valid clamping regions in machining processes

Original Article

## Abstract

In the present work, two analysis methods for analysing fixturing systems in machining processes are presented in order to determine the most suitable calmping regions. The first involves calculating the contact load at the fixture-workpiece interface using a simple and direct mathematical tool, which simplifies the deformation minimisation problem. The second method starts from the contact load data obtained and solves several cases in which the clamping position varies. From these data, it is possible to ascertain the interpolating equations, where the load contact is defined as a function of the clamping position. Then, the border curves which limit the valid clamping regions are calculated by imposing two fixturing conditions on the interpolating equations.
