VNCK - virtual machine

Due to the level of complexity and machining time associated with 5-axis milled workpieces, a
deliberate effort is made to check that the programs are free of errors before actual production
commences. To ensure that the data obtained is as realistic as possible, virtual models of the
machine and control are created and simulated. Siemens provides the following basic modules
for this purpose:
The virtual NC kernel (VNCK)
Using these basic modules and other components, such as the CAD data for the real machine,
the machine manufacturer or CAM system manufacturer can create a virtual machine that
resembles the real machine as closely as possible.
Using the virtual machine in conjunction with the SIEMENS VNCK offers many advantages:
Programming errors are detected immediately.
Program simulation with calculation of the actual time so that production effort can be
estimated more easily.
Collision checking with actual tools, clamping devices, and machine geometries.
While the current production process is underway, the workpiece can be programmed,
optimized and then implemented on the machine immediately.
Shorter setup times.
Can be used for training and instruction. New machines can be programmed without any risk.
