Programming #CYL ORI LATERAL [..]

Kinematic structure and axis identifiers

Normally the U machine axis rotates about the X axis, the V axis about Y and the W axis about Z. However, the configurations and programming examples differ from this definition. The axis identifiers for the tube system are defined to achieve logical programming in a virtual right-handed G17 lateral surface system. Therefore, tube machining is dependent on the orientation of the tube axis in the U-Y or X-V plane.

Of course, identifiers used in the NC program may also be the name of the rotary axis in both cases, e.g. U.

For tube machining the function is selected by the command #CYL ORI LATERAL […]. The kinematic structure is then selected implicitly. A kinematic parameter defines which kinematic structure is activated in the tool head on selection. The sequence of axes during selection defines whether it is a U projection (tube axis is in Y direction) or a V projection (tube axis is in X direction).

The same kinematic can be used for plate machining. Selection takes place using the command #KIN ID[90]; the kinematic is activated by #TRAFO ON. The tube axis U can be programmed as tracking axis.

The programming variant with virtual C-A axis is only required for AB, BA head configurations if the application requires machining at a bevel angle to the path. In this case the tangential tracking function can be activated. For all other head configurations there is a real C machine axis.
