TNC 407/TNC 415/TNC 425 17 Special functions for laser cutting machines 01.98
17.2 Graphic simulation without TOOL CALL
Graphic simulation is also available on machines that operate without tool definition (e.g. water jet and
laser cutters).
The tool radius for graphic simulation is defined in machine parameter MP7315. MP7316 defines the
depth of penetration of the simulated tool. The program sections to be displayed are marked with M
functions that are defined in machine parameters MP7317.0 and MP7317.1.
MP7315 Tool radius for graphic simulation without TOOL CALL
Entry: 0.0000 to 99
999.9999 [mm]
MP7316 Tool penetration depth
Entry: 0.0000 to 99
999.9999 [mm]
MP7317.0 M function at start of graphic display
Entry: 0 to 88
MP7317.1 M function to interrupt graphic display
Entry: 0 to 88
17.3 Program stop with M functions
When an M function is output in the "Program run, full sequence" and "Program run, single block"
modes, the program run is normally interrupted until the PLC reports that the M function was
executed.
This can be a disadvantage in certain applications, such as with laser cutting machines. For such
applications it is more desirable not to wait for the acknowledgement of the M function, but rather to
run the program continuously. This function can be selected through machine parameter MP7440, Bit
2. There must be no PLC positioning, datum shift, spindle orientation or limit switch during M function
output.
This function must not be used on milling machines or boring mills.
