Inclined turning
It may sometimes be necessary for you to bring the swivel axes
into a specific position to machine a specific process. This can
be necessary for example when you can only machine contour
elements according to a specific position due to tool geometry.
The control offers the following methods of inclined turning:
M144
M128
FUNCTION TCPM
with
REFPNT TIP-CENTER
If the turning cycles are executed with
M144
,
FUNCTION TCPM
,
or
M128
, the angles of the tool to the contour change. The control
automatically takes these modifications into account and thus also
monitors the machining in an inclined state.
Programming notes:
Recessing cycles and threading cycles can be run
with inclined machining only if the tool is at a right
angle (+90°, or –90°).
Tool compensation
FUNCTION TURNDATA CORR-
TCS
is always effective in the tool coordinate system,
even during inclined machining.
M144
Inclining a swivel axis creates an offset from tool to tool. The
function
M144
considers the position of the inclined axes and
compensates this offset. In addition the function
M144
aligns the
Z direction of the workpiece coordinate system to the direction of
the centerline of the workpiece. If an inclined axis is a tilting table,
meaning that the workpiece itself is inclined, the control performs
traverse movements in the rotated workpiece coordinate system. If
the inclined axis is a swivel head (meaning that the tool is inclined),
the workpiece coordinate system is not rotated.
After inclining the swivel axis you may have to again pre-position
the tool in the Y coordinate and orient the position of the tool tip
with Cycle 800.
