9.5-AXIS MACHINING FUNCTION B-63943EN-1/02
- 1138 -
If the setting of the programming coordinate system differs between
cutter compensation for 5-axis machining and tool center point control
for 5-axis machining, specifying both functions together results in
alarm PS5460. (See the following table:)

Programming coordinate system determined by bit 4 (TBP) of
parameter No. 19746 and bit 5 (WKP) of parameter No. 19696
The table rotation axis position at the start of tool center point control
for 5-axis machining and the table rotation axis position at the start of
cutter compensation for 5-axis machining must always match.
Each programming coordinate system matches the workpiece
coordinate system used when each function is started.
If these functions are started when their table rotation axis positions
differ, the programming coordinate system for tool center point
control for 5-axis machining and the programming coordinate system
for cutter compensation for 5-axis machining do not match, which
results in alarm PS5460.
Example: When the A-axis is the table rotation axis:
(Correct example)
G90 G00 A0.0
G43.4 H1
G01 Z100.0 F1000.
G41.2 D1 ← After G43.4 is specified, G41.2 is specified
without A-axis movement.
:
(Wrong example)
G90 G00 A0.0
G43.4 H1
G01 Z100.0 A30.0 F1000.
G41.2 D1 ← After G43.4 is specified, A-axis movement is
made, then G41.2 is specified.
:
* Furthermore, no A-axis command can be
included in the block specifying G41.2.
For each of cutter compensation for 5-axis machining and tool center
point control for 5-axis machining, two commands, type 1 and type 2,
are provided. Be sure to specify commands of the same type. If
commands of different types are specified, alarm PS5460 is issued.
When the tool is tilted by address Q in type 2 command specification,
if Q is specified in both of the block for starting tool center point
control for 5-axis machining and the block for starting cutter
