Aimed at multinational organizations with factories worldwide or medium size companies having several production facilities in one country, a web-based platform has been introduced by coordinate measuring machine (CMM) manufacturer LK Metrology to help production departments monitor and control inspection activities around the clock.
The new Metrology Gate portal provides remote access to information on the status and performance of all connected metrology devices, according to LK Metrology. Information available includes measurement results and a summary of errors, a record of program changes, uptime of the CMMs and OEE (overall equipment effectiveness). Historical logs assist troubleshooting and warn when routine maintenance is due, not only of the inspection machines but also of the machine tools or other equipment on which the components are being made.
Features touted by the company include delays in data searching are avoided, improving reporting procedures. Comprehensive daily reports include total output per shift and the number of parts measured, sudden changes in process averages, and comparisons between different machines producing the components. Graphical CAD reports, statistical process control (SPC) analyses with Cp and Cpk results, and environmental logs including operating temperature are generated and communicated, alongside charts to aid interpretation and understanding.
The company also says that in the case of critical dimensional discrepancies or hardware failure, the software shares the information with users immediately by sending alerts via email, SMS, WeChat or WhatsApp. Metrology jobs can be stopped and reset if performance is inadequate, maximising yield and minimising scrap. A dashboard containing details of the errors may be viewed on a web page.
Normally, data acquired is stored in the cloud but may be held on servers in different countries if preferred, or even on an individual computer. Either way, it is accessible over the internet instantly and globally in real time, on a PC in an office or using an app on handheld devices when on the move.
A hierarchical permissions structure can be built into the platform so that personnel have access only to information relevant to their seniority and requirements. The system can be phased in by implementing it in one factory and gradually expanding the network with additional licenses.
Metrology is a function in the supply chain that, even though it generates the largest amount of data, has traditionally been supported by poor infrastructure for real-time access to information. Metrology Gate is a flexible monitoring and analysis portal that addresses this shortcoming, according to LK Metrology.
