PITCH : Tap pitch
TOOL–NO. : Tool ID number of a tap. A tap having the same
nominal diameter and the same pitch is determined
automatically.
Data items other than those described above are displayed on the program
and detail data screens in the same way as for drilling.
In drilling, when a final machining process is just created for the drilling,
a necessary preprocess, tools, and cutting conditions are determined
automatically according to the data registered beforehand in the pre–tool
list.
For information about the pre–tool list, see Section 13.3.
Example of operation for automatic pre–tool determination)
(1) Create a new process by pressing the [↓] or [INSERT] soft key as in
the case of other machining processes.
(2) Tools and cutting conditions are determined automatically by
specifying tapping as the machining type, 50 mm as the hole bottom
point, 20 mm as the nominal diameter, and 1 mm as the pitch.
With the above operation, automatic pre–tool determination is
performed, and the the pre–tool process shown below is
automatically created.
(i) Pre–tool 1 (center drilling)
(ii) Pre–tool 2 (prepared hole by drilling)
