Simulation and simultaneous recording
9.1 Simulation overview
Simulation is supported with its own program interpreter (SNCK) and a separate simulation-
data environment in SINUMERIK Operate. The SNCK considers the complete syntax of the
SINUMERIK control family, including the possibility of incorporating special user options on
the machine by comparing data with the NC environment. The simulation data can be matched
statically as required with the NC environment (initialization data, macros, user data, tool data,
machining cycles) or also dynamically when tool data or machining cycles are changed.
Machining simulations, with emphasis on the drilling, milling, turning and grinding technologies,
can be performed in the workpiece coordinate system for certain machine kinematics on the
user interface of the controller:
● The simulation of the finished part is performed with the real NC data.
● The NC data is automatically compared at each change of the part program.
● The simulation allows a dynamic representation of the machining, even for active 5-axis
transformation (TRAORI) and swiveled planes.
● Turning on milling machines.
● Simulation of a machining channel for conventional milling machines.
● Simulation of up to four machining channels for turning machines with B axis.
● Intelligent determination of the block times and the program execution time.
● Very fast graphical representation through the continuous refinement of the workpiece.
● Optimum resolution for each selected picture area.
● Any sections are possible.
● In parallel to the machining of one workpiece, the machining of another workpiece can be
simulated (as of NCU 720.x).
● 3D representation of simulation (option).
General conditions for the simulation
● Very fast simulation result, this means, however, low dynamic resolution.
● For complex representations, fine recording is too slow or does not run for very complex
parts.
● "Quickview" for mold-making part programs.
● The simulation cannot be used for compile cycles with special kinematics.
