Variable Clamping Force Control for an Inteligent Fixturing
ثبت نشده
چکیده
An Intelligent Fixturing System (IFS) is currently being developed to hold a family of thin-walled workpieces for machining operations. This is a cost-effective system which uses off-line optimisation of the clamps location and on-line adjustment of clamping forces. As adaptive clamping forces appropriate to the dynamic machining environment are employed, the IFS offers higher quality of machined parts and greater robustness to disturbances. This system incorporates a fixturing system, fixture stability model, force monitoring module, clamping force optimization algorithm and clamping control system. Using off-line simulations and on-line experimental tests, the performance of the proposed IFS is evaluated and verified.

Fixture design is critical to the development of a mesoscale machining system capable of yielding micro-size features with high accuracies. A reconfigurable, intelligent fixturing system with embedded sensors is required (i) to fixture a large group of similar workpieces with minimal set-up changes, (ii) to sense the location of the workpieces placed on the fixture, (iii) monitor clamping force...
متن کاملAn Integrated Model of a Fixture–Workpiece System for Surface Quality Prediction
Surface quality is a major factor affecting the performance of a component. The machined surface quality is strongly influenced by the external loads during the fixturing and machining processes. In machining process development, it is highly desirable to predict the quality of a machined surface. For this purpose, an integrated finite element analysis (FEA) model of the entire fixture–workpiec...
