5.5 Transformations

To make programming easier, you can transform the coordinate system.

Use this function, for example, to rotate the coordinate system.

Coordinate transformations only apply in the current program.

You can define offset, rotation, scaling or mirroring.

You can select between a new or an additive coordinate transformation.

In the case of a new coordinate transformation, all previously defined

coordinate transformations are deselected. An additive coordinate

transformation acts in addition to the currently selected coordinate

transformations.

ShopTurn supports:

Offset (see section 5.5.4)

For each axis, you can program an offset of the zero point.

Rotation (see section 5.5.5)

You can turn the X and Y axes through a specific angle.

A positive angle corresponds to counterclockwise rotation.

On turning machines without a physical Y axis, problems with the

coordinate system can occur if the axis is rotated.

Scaling (see section 5.5.6)

You can specify a scale factor for the active machining plane, as well as

for the tool axis.

The programmed coordinates are then multiplied by this factor.

Mirroring (see section 5.5.7)

Furthermore, you can mirror all axes.

Enter the axis to be mirrored in each case.

Rotation of the C-axis (see section 5.5.8)

You can turn the C axis through a specific angle to enable subsequent

machining operations to be performed at a particular position on the end

face or peripheral surface.

The direction of rotation is set in a machine datum.
