Caution – Software safety

The software you have purchased is used to control the movements of a machine tool. It has been

designed to cause the machine to operate in a speciﬁed manner under operator control, and has been

conﬁgured for a particular combination of machine tool hardware and controller.

Renishaw has no control over the exact program conﬁguration of the controller with which the software

is to be used, nor over the mechanical layout of the machine. Therefore, it is the responsibility of the

person putting the software into operation to:

• ensure that all machine safety guards are in position and are correctly working before

commencement of operation;

• ensure that any manual overrides are disabled before commencement of operation;

• verify that the program steps invoked by this software are compatible with the controller for which

they are intended;

• ensure that any moves which the machine will be instructed to make under program control would

not cause the machine to inﬂict damage upon itself or upon any person in the vicinity;

• be thoroughly familiar with the machine tool and its controller, understand the operation of work

coordinate systems, tool offsets, program communication (uploading and downloading) and the

location of all emergency stop switches.

IMPORTANT: This software makes use of controller variables in its operation. During its execution,

adjustment of these variables, including those listed within this manual, or of tool offsets and work

offsets, may lead to malfunction.

Delta Transformation

Delta Transformation is a licence option installed as part of Renishaw OMV and Renishaw OMV

Pro which enables users to set up components on a CNC machine tool using a Renishaw OMV (or

Renishaw OMV Pro) measurement and alignment sequence to help reduce both set-up time and

costs.

It can also be used to transfer calculated best ﬁts to the machine tool controller, allowing the

remachining of repositioned, free-form components.

Accessing Delta Transformation

In Renishaw OMV, select Delta Transformation .

In Renishaw OMV Pro, select Miscellaneous

followed by Delta Transformation .

Creating a part alignment

Within an open session of Renishaw OMV or Renishaw OMV Pro, create the required measurement

and alignment. All available alignment types are valid.

In the image below, plane, line and circle features have been measured to enable a Geometric PLP

(plane line point) alignment.

Post process the session containing the alignment and run the resulting program on the CNC machine

tool.

Load the measured results from the component into Renishaw OMV (or Renishaw OMV Pro) using the

standard procedure.

10 Delta Transformation for Renishaw OMV and Renishaw OMV Pro

Publication no. H-5369-8505

Applying the part alignment

Ensure the open session of Renishaw OMV (or Renishaw OMV Pro) contains a measured part and an

active alignment.

Open Delta Transformation as described in “Accessing Delta Transformation” on page 9.

The ‘Delta Transformation’ application dialog will open and will list the alignments from the open

session.

Local Coordinate System

Values within the generated program can be relative to CAD coordinates or machine coordinates.

Select the appropriate coordinate system from the drop-down menu.

Reference Alignment1

This is the alignment which represents the measured workpiece position.

Use the drop-down menu to select the required alignment.

Reference Alignment2

This is the alignment that is to be used as the base alignment.

Use the drop-down menu to select the required alignment.

Export

To export the Delta Transformation as an NC program ﬁle that can then be run on the machine tool,

click on the ‘Export to NC code’ button

11Delta Transformation for Renishaw OMV and Renishaw OMV Pro

Publication no. H-5369-8505

In the resulting NC Program dialog, use the ‘Export to’ drop-down menu to select the machine tool

controller type and then click OK.

Select a location on the PC to save the generated NC program ﬁle to.

When run on the CNC machine tool, this ﬁle will update the NC control to use the alignment from the

Renishaw OMV (or Renishaw OMV Pro) session. Any NC programs executed subsequently on the

CNC machine tool will use this alignment.

NOTE: Users need to ensure that the NC machine program does not reset or clear the alignment, as

the NC cutting program may contain code to cancel or overwrite the Delta Transformation alignments.

PowerMILL

Output ﬁles can also be generated for use in Delcam’s PowerMILL application with the transformation

of each part exported to PowerMILL as a workplane.

This workplane is transformed around the world coordinate system, although it can also be

transformed relative to another workplane if one exists and is active.

Open PowerMILL.

In the Export section of the Delta Transformation dialog click on the ‘Export to PowerMILL as a

workplane’ button

The world coordinate system is displayed on the left of the PowerMILL window with the workplane

exported from Delta Transformation displayed on the right of the window.

Details of the transformation applied to the world coordinate system are displayed in the ‘Information’

dialog.

Export to File

Delta Transformation can be output as a matrix (.mat) or IGES (.igs) ﬁle. These can be subsequently

imported into third party CAD systems.

In Delta Transformation click on the ‘Export to ﬁle’ button

. Give the Delta Transformation a name of

your choice and then click on ‘The transformation is to be saved as’.

This ﬁle can then be imported into a CAD package.

Language

Delta Transformation is available in every language that is supported by Renishaw OMV and Renishaw

OMV Pro and will run in the same language that the main application is set to operate in.

To change the operating language of Renishaw OMV (or Renishaw OMV Pro) close any open

sessions of the application and select Edit > Language from the menu bar.

This will open the ‘List of all available languages’ dialog.

Select the required language and click OK.

The operating language of the application will be changed immediately: it will not be necessary to

restart the application.

Compatibility

At present, Delta Transformation is compatible with the following CNC controllers:

• Fanuc 0i and 31i

• Fidia C20

• Heidenhain

• Mazak

• Siemens

Please contact your local Renishaw distributor if your controller type is not currently supported.

NOTE: The templates supplied within the application provide one method of aligning a component. As

each controller can have several methods, Delta Transformation can be conﬁgured to suit individual

requirements.
