Controller-integrated predictive oscillation compensation for machine tools with parallel kinematics

摘要: Abstract Since computerised numerical control (CNC) systems were introduced into the field of mechanical engineering, manufacturing technology made significant progress. In spite drastic improvements, mainly in terms productivity and precision (e.g. finishing surface quality), opportunities for further advancements processes still exist. One possible method increasing is to adopt a machine structure with parallel kinematics. This kinematic can enhance system dynamics, because moving mass divided among all actuators, contrary conventional, cartesian structures. The problem, which exists even this new structural solution, oscillation that appears during machining. may decrease machining accuracy. paper highlights compensate by using controller-integrated compensation principle. Because principle, additional components piezo stacks, actuators) are not necessary. concept was developed verified under Matlab/SIMULINK then installed centre Dyna-M. Dyna-M defined as hybrid-kinematic also one typical obtained results show up 60% reduction prove practical usability system.
