New system allows multiple tool setting and inspection probes on CNC machine tools

The new RMI-Q radio transmission interface allows up to four separate tool setting or spindle-probes with radio transmission to be operated on the same CNC machine, making it an excellent choice for fitment onto CNC machining centres, or machines with rotary tables or twin pallets.  The cable-free system is easily integrated on a wide range of machining centres and CNC milling machines, enabling users to enjoy all the benefits of Renishaw probe systems, including automated on-machine tool setting, tool breakage detection, part set-up and part verification capability.

A multitude of different multiple probing configurations are possible, typically comprising of the new Renishaw RTS tool setter with Renishaw RMP60 inspection probe, or other compatible spindle-mounted touch probes with radio transmission such as RMP40 or RMP600, selected to suit the users specific application requirements.

The new RMI-Q is used to activate either the spindle-mounted touch probe or table-mounted tool setting probe, and gives visual indication of the activated device.  Like the new RTS tool setter it features the tried and tested 2.4GHz frequency hopping spread spectrum (FHSS) radio transmission, designed to be compliant with radio regulations worldwide, which enables uninterrupted operation in increasingly busy radio environments.

The system is suitable for applications that have obscured line-of-sight between probe and receiver, and its transmission range of up to 15m makes it particularly suitable for large machines.  The RMI-Q has all the functionality of Renishaw's proven RMI interface, plus additional features, including the ability via a simple macro to partner all required probes to the interface in a single operation.  Additionally when RMI-Q is used in conjunction with an RTS tool setter and radio spindle probe it is possible for a simple automated calibration cycle to be run using the RTS stylus as the calibration artefact.

Renishaw's new RTS contact tool setting probe with radio transmission is a robust, compact and cable-free product which does not restrict table movement. It offers users fast and accurate tool measurement, including tool length and diameter of milling cutters, twist drills and end mills, plus broken tool detection. Signals from the probe are communicated using radio transmission which makes it ideal for large machines, where line-of-sight is an issue, and for machines with twin pallets or rotary tables, which historically have proven challenging for installations of hard-wired tool setters.

Powered by two standard AA batteries and benefiting from significantly extended battery life, the RTS can be used in conjunction with up to three other radio probes using the new RMI-Q product and is also compatible with the current RMI radio interface.
