Virtual Machining and Robotic Assisted Machining
By identifying the problems such as high form errors and surface quality resulting from cutting forces, vibrations and residual stress related distortions, process planner can change process parameters beforehand so that cycle time is minimized while respecting the constraints in the machining system. Hence, costly trial and error approach on the machine tool are avoided. Moreover, integration of simulations and measurements on the machine tool brings additional capabilities. Measurements on the machine are used initially to fine tune the models against not modelled effects. Accurate models can be used to provide reference data in the monitoring strategy which minimizes the setup time of the process monitoring system and avoids false alarms.
Robotic assisted machining is a process where a robot assists a machining process by providing support to a workpiece while machine tool machines it. The robot's support is especially effective on thin wall components which are common in aerospace sector. Assistance of the robots was shown to decrease form errors and improve surface quality of the part.
