3. EXECUTION OF
OPERATION BY Symbolic FAPT
If the entered tool data includes “tool tip width,” no prompt
is made for the “CUTTING METHOD TP.” In this case,
“single–edge thread cutting with constant cutting amount”
is used in machining.
The prompt to ask the maximum spindle speed is selected
by system parameter No.702 bit 0.
0: No prompt.
(The maximum spindle speed is set by system parameter
1: The prompt for the maximum spindle speed is displayed
on each stage of machining process.
(Ignore the value of system parameter No.128.)
However, the prompt is not displayed at the process
where the constant tangential speed control is not used
set in system parameter Nos.107 to 115.
The value set in system parameter No.128 is output at
If the same tool is used for more than one process, the
prompt is not displayed.
If system parameter 140 is specified so that cutting off is defined, CUT
OFF is displayed on the screen which defines the type of machining.
On this screen, the cutting off data can be specified.
