Beschreibung

To meet the requirements of today´s cutting process of natural stones thin disk-shaped tools with large diameter are applied at high cutting velocities. To use these tools, guiding systems for the disks are needed. Therewith, tool vibration magnitudes and deflections can be reduced. The risk of pro-ducing scrap parts or tool damage are decreased. However, the guidance being placed close to the cutting zone reduces the cutting depth, so that the process is limited to the production of small slabs and tiles. To use the advantage of a guidance without limiting depth of cut, a new guidance concept is presented. Thereby the guiding areas are placed opposite to the cutting zone. This enables the reduction of tool vibration without decreasing the depth of cut. In this paper the compensation of tool vibration by this guiding concept is investigated. Different types of guidance are compared and the most suitable compensation approach is identified. Further on, the problem of the decreasing com-pensation effect, due to the increasing distance between the excitation and the guidance is consid-ered. To increase the compensation effect, the guidance is optimized regarding to the number and positon of guiding areas. The capability of the presented concept is verified by a comparison with a conventionally placed guiding system.
