Abstract
The main products of natural stone are tiles of various sizes for the decoration of floors and walls. In most cases these tiles are cut out of stone blocks by circular diamonds tools especially developed for this purpose. The main disadvantage of this technology is the high proportion of removed material (>50%). This paper presents a new tool and machining concept in order to reduce the width of the slots in the stone block from common 7.0 mm to 4.00 mm. Concerning this goal there is a requirement for thinner steel centres and segments as far as adapted cutting parameters. Especially the reduced thickness of thin discs cause problems regarding a changed stiffness and vibration behavior. By the help of a mathematical calculation it was stated that it is possible to substitute the reduced static stiffness by an increased dynamic stiffness generated by a higher cutting speed. Based on this knowledge investigations regarding increased cutting speeds up to 50 m/s have been carried out taking special account to the process forces, the wear behavior of the diamond segments, the vibration behavior of the steel centre as well as the noise level during the cutting process.
