8.3 Tool-oriented machining
Fundamentals of tool-oriented machining
Application
Refer to your machine manual.
Tool-oriented machining is a machine-dependent
function. The standard functional range is described
below.
Tool-oriented machining allows you to machine several workpieces
together even on a machine without pallet changer, which reduces
tool-change times.
Limitation
NOTICE
Danger of collision!
Not all pallet tables and NC programs are suitable for tool-oriented
machining. With tool-oriented machining, the control no longer
executes the NC programs continuously, but divides them at the
tool calls. The division of the NC programs allows functions that
were not reset to be effective across programs (machine states).
This leads to a danger of collision during machining!
Consider the stated limitations
Adapt pallet tables and NC programs to the tool-oriented
machining
Reprogram the program information after each tool in every
NC program (e.g.
M3
or
M4
).
Reset special functions and miscellaneous functions before
each tool in every NC program (e. g.,
Tilt the working
plane
or
M138
)
Carefully test the pallet table and associated NC programs in
the
Program run, single block
operating mode
The following functions are not permitted:
FUNCTION TCPM, M128
M144
M101
M118
Changing the pallet preset
The following functions require special attention, particularly for mid-
program startup:
Changing the machine statuses with a miscellaneous function
(e.g. M13)
Writing to the configuration (e.g. WRITE KINEMATICS)
Traverse range switchover
