Abstract
En 中文
Modular fixtures are used to ensure the orientation and position of workpiece during machining, inspection and assembly. Specific to modular fixture due to the complexity, overall size and the high number of components, the general stiffness if affected. In this paper there are presented the causes that can lead to the diminishing of the accuracy of clamping when using modular fixtures, and several deformation patterns that result from experimental research of multiple joints modular structures, that can lead to a series of deviations of orientation-positioning and clamping deviations during clamping and machining. Specific clamping cases are presented and evaluated from the point of view of deviations caused by diminished rigidity during machining of parts clamped in modular fixtures.
