Production equipment, such as metal cutting machine tools, can be monitored directly, continuously and in real time. The data generated in this way are used to display and monitor current conditions and to trigger automatic reactions if limit values are exceeded. This allows, for example, for responsible employees to be alerted. The available data storage space determines the extent to which the data can be used for the analysis of processes, tools and machines.
Based on data stored externally (e.g. in machine controls), individual programs such as STATISTIC or PROCESS DOCUMENTATION can be used to compare current and historical data. A comprehensive evaluation covering longer periods of time or larger data amounts, however, has its limits here.
Extended production and monitoring data need to be included to predict upcoming events and enable appropriate planning. The often unused data from sensors and modules can make a valuable contribution to maintenance and production planning, as they can be used when changes occur to spindles, axes and tools. A comparison of current with historical data then serves as the basis for predictive maintenance and allows predictions to be made about failing components, tool wear or other problems.
