(2) Chamfering process
TOOL–NO. : Number of the chamfering tool (used for tool
management)
T–CODE : T–code for a chamfering tool
REV/MIN : Tool speed (rpm) for chamfering
FEED/MIN : Feedrate (mm/minute or inches/minute) for
chamfering
JMILLNGGEAR : Milling gear selection for chamfering (only
when needed)
JCOOLANT : Cutting oil specification
Data items other than those described above are displayed on the program
and detail data screens in the same way as for C–axis machining.
To define a contour, figure specify the center line (dashed line) of the
