9.5-AXIS MACHINING FUNCTION B-63943EN-1/02
- 1136 -
9.5.4.2 Restriction on tool rotation type
- Unavailable commands (leading edge offset)
In the G41.3 mode, the following commands cannot be specified:
- G functions of group 01 other than G00 and G01
- Use with tool center point control
If cutter compensation for 5-axis machining is specified before tool
center point control when cutter compensation for 5-axis machining
and tool center point control are specified together, tool center point
control must be canceled before cutter compensation for 5-axis
machining is canceled (Example 1). Contrariwise, if tool center
point control is specified before cutter compensation for 5-axis
machining, cutter compensation for 5-axis machining must be
canceled before tool center point control is canceled (Example 2).
Example 1

G43.4 H1

:
G40
Example 2

G41.2 D1

:
G49
If the specification sequence of G40 and G49 is reversed, alarm
PS5460 is issued.
When cutter compensation for 5-axis machining is specified before
tool center point control, the block for canceling tool center point
control suppresses buffering. Note that, as a result, the block before
the G49 block generates a compensation vector for cutter
compensation for 5-axis machining, which is perpendicular to the
movement.
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
compensation for 5-axis machining, the Q command specified earlier
becomes valid.
