OPERATION BY Symbolic FAPT
3. EXECUTION OF
Even when the tool path and machining processes
specified in NC data are verified by the NC data check
function, if the data relating to the actual tool offset and
workpiece shift is incorrect, the tool may collide with the
workpiece and/or machine, possibly causing damage to the
machine and/or tool itself, or injury to the user. Before
starting a production run, perform a dry run to ensure that
the tool will not collide with the workpiece or machine. For
example, specify a low feedrate, then start the NC program
without mounting a workpiece on the machine.
In 16–TC CAP II, 16i–TA CAP II, and Symbol CAPi T, the animated
simulation function has been improved.
When using the above CAP II models, see Part XIII, “ANIMATED
SIMULATION FUNCTION II.”
The function which allows a practical cutting simulation to take place by
displaying the blank, chuck, tailstock and tool configuration is called an
Animated Simulation Function.
The manner in which a blank is being cut can be monitored by
1) selecting the screen on which animated simulation is done and
2) executing cycle operation under the machine lock condition and each
time a T code is specified, the tool drawing changes.
(1)Prepare NC data by using the symbolic FAPT function, and enter it
into the NC memory.
(2)Set the coordinate system so that work coordinates of the tool may
meet when a program is started. Alternatively move the tool manually
or automatically until it is in the correct position.
(3)Select Menu 6, “CHECKING OF NC DATA” and depress the soft key
(4)Execute the NC program in Machine Lock Mode. The tool drawing
moves according to the given commands and the manner in which the
blank is cut can be monitored.
