This paper proposes a novel motion controller for CNC to achieve the purpose of high-speed and high-accuracy motion control with modular design. Fuzzy PID with feedforward control strategy is employed to improve the whole system dynamic performance and control precision. A simulation experiment is made to show the validity of the strategy adopted, and another machining experiment to verify the overall...
Product with complex surface could be applied in many industry fields, such as automobile, airplane, household appliances and so on. The gap between design model and machining model brings many troubles in fast, effective and precise transition process from design to manufacture. Design, machining and measurement of complex surface become keys to improve product quality. By subdivision application,...
With the increasing demand for the spiral bevel gears(SBGs) in the modern industry, the multi - axis CNC machining tools for SGBs was deeply investigated in the mathematics model of gear meshing, design and simulation, numerical controlling method and measurement method to improve the accuracy and precision of machining. This paper constructs a compensation method for SBGs machining with four - axis...
The reconfigurable hardware has been widely applied in Computer Numerically Controlled (CNC) systems. The reconfigurable hardware provides high performance and flexibilities for the designer. This work presented a novel CNC controller architecture using reconfigurable hardware. Several logic modules, including a new resampling module for threading, are designed to support the reconfiguration process...
