SINUMERIK ONE opens up a new chapter with Run MyVirtual Machine /3D. This add-on option for the virtual SINUMERIK provides an exact image of the real manufacturing environment, in other words the machine room, clamping devices and tool holders. This allows realistic, stress-free testing and optimization of CNC programs, which significantly reduces changeover times, especially for complex machines. It is also possible to verify the manufacturing feasibility of jobs in advance, for example with compact 5-axis machining centers. This is a great benefit, especially in job order production. The integrated collision detection function determines at the job preparation stage whether the tool will collide with the component, the workholder, or with the machine itself. The risk of unexpected machine failures is therefore significantly minimized. Last but not least, operators can be trained not only offline in the use of the CNC, but also in the handling of the machine itself.
