Interpolation takes motion control into
new areas
Interpolation is the ability to move in a co-ordinated linear and circular path rather than just straight lines and latest software makes it available for all applications.
In simple terms, Interpolation is the ability to move in a co-ordinated linear and circular path rather than just straight lines Previously the preserve of CNC controllers, it is now available for all applications using Rockwell Automation's latest Logix programming software

Ethernet switch is optimised for EtherNet/IP
Rockwell Automation's latest industrial Ethernet switches are integrated with Cisco technology to effectively manage real-time control and information flow.
Ethernet switches/infrastructure products launched
A full range of Ethernet switches and infrastructure products includes managed switch co-branded with Cisco, integrating Cisco technology and optimised for EtherNet/IP.
Perfect for delicate pick and place applications where the path might need to avoid other equipment or for sophisticated, constant velocity path drawing such as laying down liquid gaskets in the automotive industry, interpolation opens up a host of uses previously impossible with 'everyday' motion control.
In contrast to the days of 'G and M Codes' used by CNC controllers, programming is extremely easy.
The user creates an interpolated move by defining the two or three axes to be controlled.

Diagnosis and maintenance of machine tools
Rockwell Automation has introduced the QC10 ballbar which gives maintenance technicians a tool for assessing the dynamic motion and positioning precision of machine tools and production machinery.
Then the linear or circular move is defined using the standard IEC based programme (using ladder logic, for example).
A 'Via' command takes the path through given points in an arc; 'centre' calculates an arc from the centre of a circle; or 'radius' calculates the arc from a given radius.
The built in, on screen, plot facility then allows the progress of the path to be monitored to ensure that it is correct before applying it to the real application.
Typical applications include advanced pick and place, liquid gasket laying machines where the profile is generally 'taught' during commissioning and then 'replayed' - with a menu of several to choose from depending on the job in hand.
Also, flame cutting (for metal) and water cutting (for food), where the shape to be cut can be imported from a PC holding the XY co-ordinates, using an OPC link and vinyl cutting which as like the above with the third axis being used to control the angle of the knife so that it is always pointing in the direction of travel.
The Logix platform behind the system, is an outstanding new generation architecture that integrates logic, motion and process control.
Specifically designed for networks, it is programmed using a single software package.
Rockwell Automation has recently taken the engineering of motion control systems to a new level with the introduction KINETIX, a range of easy to use controllers and software, high performance motors and servo drives, and extensive use of SERCOS for easy connection and feedback.
Now with the addition of an easy to use, cost effective interpolation solution, even the most sophisticated applications are within the capabilities of non-specialist engineers. Request a free brochure from Rockwell Automation ...
