WITH TWO OPPOSING SPINDLES
B–63304EN/02
1. CAP II FOR TWO–PATH
LATHE WITH TWO
OPPOSING SPINDLES
758
D For the method of determining the cutting area for the C–axis
machining process, refer to chapter X. BACK MACHINING
FAPT, section 2.1.4 Machining definition, (5) Cutting direction
and cutting data of the CONVERSATIONAL AUTOMATIC
PROGRAMMING FUNCTION FOR LATHE OPERATORs
MANUAL, B–61804E–2/04.
(4)Cutting Condition
Method for determining the cutting condition is the same as that of
conventional CAP II for 1path or 2path lathe. Refer to chapter III.
PROGRAMMING AND OPERATION BY Symbolic FAPT, section
3.4.8 Cutting conditions, of the CONVERSATIONAL AUTOMATIC
PROGRAMMING FUNCTION FOR LATHE OPERATORs
MANUAL, B–61804E–2/04.
(5)Notes
(a) Front face features cannot be machined in the secondary cutting
process and rear face features cannot be machined in the primary
cutting process.
(b)BAR FEED and CUTTING OFF machining cannot be specified
for the secondary machining process.
(c) Define the machining steps in the sequence with the primary
machining processes first and the secondary machining processes
next. Staggering the primary and the secondary machining
processes results in a part program with which the machine does
not operate correctly.
(d)The automatic process determination function cannot be used for
the part which has a feature or features machined in the secondary
machining process.
(e) Automatic determination of the cutting area is not available for the
secondary machining portion of the work.
(f) Y–axis machining cannot be programmed.
(g)Do not specify the cutting area so that start point and/or end point
of the part figure is included in it as shown in the following figure.
Wrong cutting area will be created as a result.
