Reading aloud A new intelligent impact drill can think along. It optimally adjusts itself to different drills, the material to be processed and even the way the user works. This drilling machine of the future is presented by the Fraunhofer Institute for Information and Data Processing (IITB) in Karlsruhe in a press release. Man, hammer drill and wall form a complete mechanical system, explains Helge-Björn Kuntze from the IITB. "The operator presses and moves the machine differently, and wall strength varies from case to case." The speed at which a drill advances ultimately depends on the speed of the drill and the frequency of the hammer mill. The engineers at IITB have developed an intelligent drive control system in order to optimally coordinate the sizes and achieve maximum drilling feed.

Several sensors in the machine measure, inter alia, impact and speed and the performance. Their data are forwarded to the electronic drive control of the percussion drill. From this information, the electronics calculates the current conditions such as drill and rock type and the contact pressure and ensures that the impact drill works with the optimum settings.
