10.1.1 Attitude Control A (Zero Offset Type Nozzle)
The nozzle tip position fixed type (zero offset type) mechanism is
configured with the α axis (4th axis) to rotate around Z axis, and the
rotational axis β axis (5th axis) recorded in this α axis. It possesses
the structure that the tip of the nozzle is arranged at the point where
the rotational center
line of the α axis crosses the rotational center line of the β axis.
This type has the following characteristics:
1 Movement of the nozzle tip position is performed by X, Y, Z
axes, and the attitude control of the nozzle is performed by α, β
axes. Therefore, movement of the position and attitude control
can be controlled independently.
2 Contour precision is good because control is easy.
3 Operability is good.
4 The structure of the nozzle head section is complicated and
easily interferes with the workpiece.
5 The number of mirrors becomes great.
