Smart tooling insert promises productivity boost

The sensing device, developed by the Advanced Manufacturing Research Centre (AMRC) with funding from Innovate UK, will allow operators to monitor the condition of cutting tools without having to stop the machine for a manual inspection.

In this way it could save both time and money, according to Hatim Laalej, AMRC Machining Group Technical Lead for Control Systems, Sensors and Data Acquisition.

“The standard procedure is [for operators] to keep watching the tool, and if they see anything untoward to stop the machine to check its condition,” said Laalej. “But any stoppage is undesirable because you lose production time."

What’s more, operators will sometimes change a tool before the end of its life, in order to avoid damaging an expensive part if it does become worn, he said.

The prototype device, which uses low-cost electronics, is embedded with sensors that produce data about the current condition of the cutting tool. This data is then converted and sent wirelessly to the machine panel or the operator’s control pad, allowing them to determine the condition of the tool without stopping the machine.
