Renishaw has made a number of additions to its range of radio transmission probe systems, including the RMI-Q radio transmission interface, which allows up to four separate tool setting or spindle-probes with radio transmission to be used on the same CNC machine.

It is suitable for CNC machining centres, machines with rotary tables, or twin pallets, the company said. A number of probing configurations are possible, Renishaw explained. Examples here include the company’s RTS tool setter with its RMP60 inspection probe and other compatible spindle-mounted touch probes with radio transmission.

The 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 RTS tool setter it features the established 2.4GHz frequency hopping spread spectrum (FHSS) radio transmission. This is designed to be compliant with radio regulations worldwide and thus to enable uninterrupted operation in busy radio environments. The system is said to be suitable for applications that have obscured line-of-sight between probe and receiver. Its transmission range of up to 15m makes it particularly suitable for large machines, the company noted.

During machining, dimensional accuracy dependes on a number of variables, including; tool size deviation, tool/holder run out and tool breakage. Renishaw said its RTS contact tool setter can compensate for variation during the machining process and automatically update the controller to account for actual effects, such as tool wear, as well as enabling automatic process stoppage when broken tools are detected.

The new RTS contact tool setting probe is claimed to be robust, compact and cable-free. Signals from the probe are communicated by radio, making it approriate for machines of any size where line-of-sight is an issue, and for machines with twin pallets or rotary tables. The RTS can be used in conjunction with up to three other radio probes using the new RMI-Q product.
