Integrations of lasers in machine tools for hot machining
Abstract
Demands for lower costs and higher productivity lead to innovative developments in production technology. The integration of lasers into conventional turning or milling machines helps to reduce production time and enhance accuracy as the entire manufacturing is done in one setting. By combining machining operations with laser processing, new technologies such as laser-assisted machining (hot machining) can be realized. For the integration of lasers. the following points are of special interest The design of optical elements, the combinatorial circuit of the laser and the control system of the machine tool as well as safety aspects. Hereunder, various details will be discussed and explained with the help of different examples. The required process control for hot machining was successfully realized by a closed loop control. The pollution emission when turning siliconnitride-ceramics was evaluated. Tests were made to characterize the fine dust particles. Experiences made and necessary pr ecautions will be introduced.
