TOOL–NO. : Tool ID number for a reamer. A reamer having a
nominal diameter equal to that of the drilled hole is
determined automatically.
JSTART FEED: Cutting feed amount at the start of cutting.
<Related parameter: No. 9050, STFECF>
The cutting feed amount at the start of cutting is
calculated as follows. It can be changed manually.
(STFECF)
100
(Usual cutting feed amount) ×
END FEED (only for a through hole):
Cutting feed amount for the last cut for a through hole.
(Related parameter: No. 9051, ENFECF)
The cutting feed amount for the last cut is calculated
as follows. It can be changed manually.
(ENFECF)
100
(Usual cutting feed amount) ×
JRETURN SPD: Feedrate for retraction to the cutting start point upon
the completion of reaming.
<Related parameter: No. 9860, RMBROV>
The feedrate for retraction is calculated as follows. It
can be changed manually.
(RMBROV)

(Usual cutting feed amount) ×
Data items other than those described above are displayed on the program
and detail data screens in the same way as for drilling.
