There is a continuing demand in machine tools for an increase in productivity. This can be achieved by higher speeds and process parameters, which demand structures with a high stiffness to weight ratio including the use of materials with a high specific modulus. The lack of standardized interfaces and more complex design and manufacturing process prevent the broad use of these materials. This applies especially for CFRP (carbon fiber reinforced polymer) which has the highest specific modulus compared to conventional construction materials. Due to that and the higher material damping in comparison with steel, parts out of CFRP can improve the precision of machine tools. These advantages often remain unutilized because of the challenging integration of CFRP parts. Therefore, this paper presents an innovative approach to use CFRP in a hybrid design for machine tool structures focusing on improved dynamic behavior, increased specific stiffness, and ease of manufacture.

对机床的持续需求是提高生产率。这可以通过更高的速度和工艺参数来实现，这需要具有高刚度重量比的结构，包括使用具有高比模量的材料。缺乏标准化的接口以及更复杂的设计和制造过程阻止了这些材料的广泛使用。这尤其适用于与常规建筑材料相比具有最高比模量的CFRP（碳纤维增强聚合物）。因此，与钢相比，材料阻尼更高，CFRP以外的零件可提高机床的精度。由于CFRP零件具有挑战性的集成，这些优势经常未被利用。因此，
