- Specification of rotation axes
(1) Type 1
When only the rotation axes are specified in tool center point
control (type 1) mode, the feedrate of the rotation axes is set to the
maximum cutting feedrate (parameter No. 1422).
(2) Type 2
In tool center point control (type 2) mode, the rotation axes cannot
be specified. If the rotation axes are specified, alarm (PS1061)
occurs.
- Positioning (G00)
NOTE
1 Set the following parameters:
(1) Bit 4 (LRP) of parameter No.1400 = 1:
Linear-type rapid traverse
(2) Bit 5 (FRP) of parameter No.1603 = 1:
Acceleration/deceleration before interpolation is
used in rapid traverse.
(3) Parameter No.1671:
Acceleration of acceleration/deceleration before
interpolation for rapid traverse
(4) Parameter No.1672:
Acceleration change period of bell-shaped
acceleration/deceleration before interpolation for
rapid traverse
2 If the above settings are not made, or if look-ahead
acceleration/deceleration before interpolation is not
valid, axis movement may be performed at a higher
feedrate than the rapid traverse rate.
- Operation at start and cancellation
(1) Type 1
When tool center point control (type 1) starts (G43.4H_) and
when it is canceled (G49), the CNC calculates the compensation
vector only at the end of the block.
(2) Type 2
When tool center point control (type 2) starts (G43.5H_) and
when it is canceled (G49), the CNC calculates the compensation
vector only at the end of the block.
- Operation of tool center point control (type 1)
The following items are the same as for tool length compensation along
the tool axis:
- Machine configuration example and equation for rotation axis
calculation
- Tool holder offset
- Specification of angular displacement in a parameter
- Zero-point compensation for the rotation axes
- Rotation axis offset
