Transformation with gaps in the axis (P-CHAN-00213)

P-CHAN-00213

Permit gapped axis configuration when a transformation is selected

Description

When Cartesian or kinematic transformations are used, an axis configuration free from gaps is expected. When selected, the CNC checks whether the required number of axes exists with no gaps in the current configuration; if necessary, an inserted simulation axis can complete the axis configuration.

In special cases, it may be necessary to permit axis configurations with gaps, e.g. a tool head without physical Z slides. For example, an axis configuration with gaps can be recognised by the non-linear increase in the axis index sequence in the CNC axis exchange command and the insufficient number of axes; see the following example of a 5-axis kinematic RTCP transformation.

Axis configuration with no gaps using NC command:

#SET AX[X, 1, 0][Y, 2, 1][Z, 3, 2][C, 4, 3][A, 5, 4]

Axis configuration with gaps using NC command:

#SET AX[X, 1, 0][Y, 2, 1][Z, 3, 2][C, 4, 3] ;number of transformation axes too low

SET AX[X, 1, 0][Y, 2, 1][Z, 3, 2] ; number of transformation axes too low

#SET AX[X, 1, 0][Y, 2, 1][Z, 3, 2][C, 4, 3][A, 5, 5] ; A no transformation axis

Parameter

gap_in_trafo_axis_sequence

Data type

BOOLEAN

Data range

0: Axis configuration with gaps not permitted (default).

1: Gaps in axis configuration are permitted

Dimension

----

Default value

0

Remarks

Should only be used in exceptions. We recommend that main axes should always be created completely with no gaps.

Only permitted with RTDP transformations.
