The Research And Application On Virtual Machining System Of Dual-spindle Turning Center

The dual-spindle turning center is an advanced machine, which is based on theturning machine by adding dynamic milling, drilling, boring and counter-spindle, canmake the complex part clamping and finish machining in one time, improve themachining quality and efficiency. However, due to the dual-spindle turning center is notonly has complicated structure, also it’s milling, turning and other different machiningmode, the NC program is not easy to achieved and difficult to checked in the practicalapplication, all these questions restricted the efficient application of turning center allthe time. This paper treats EMCO MAXXturn65dual-spindle turning center as theresearch object, the construction of virtual simulation machining system, thedevelopment of special post processor and the optimization of processing technology onit were studied.The virtual manufacturing system of machine was built based on VERICUT in thispaper, aimed at the characteristics of machine’s structure and CNC system. The specialpost processor was developed based on the IMSPOST platform, realized the NCprogram’s automatic generation and virtual simulation machining. Taking the virtualsimulation machining aim at a part in the constructed virtual simulation machiningsystem, verify the correctness of NC program, and predict the processing of theinterference, collision and cutting process problems. Produce this part in dual-spindleturning center, verify the correctness and reliability of the virtual simulation machiningsystem.The actual processing production proved that the developed special postprocessoraimed at dual-spindle turning center could process the APT files correctly, and achievethe right NC program. The virtual simulation machining system based on VERICUT can realize simulation machining effectively, check process problems that interference,collision, overcut and so on. Reduce the trial cut link effectively, reduce the materialloss and machine’s takes up time, make sure the safe and reliable running of NCmachine tool, take the optimization of the machining process of dual-spindle turningcenter at the same time, improve the machining quality and efficiency effectively. Theresearch result has great guiding significance of high efficient application on thedual-spindle turning center and multi-spindle machine.
