Especially for slicing hard and brittle materials, wire sawing with electroplated diamond wires is widely used since it combines a high surface quality with a minimum kerf loss. Furthermore, it allows a high productivity by machining multiple workpieces simultaneously. During the machining operation, the wire/workpiece interaction and thus the material removal conditions with the resulting workpiece quality are determined by the material properties and the process and tool parameters. However, applied to machining of carbon fibre reinforced polymers (CFRP), the process complexity potentially increases due to the anisotropic material properties, the elastic spring back potential of the material, and the distinct mechanical wear due to the highly abrasive carbon fibres. Therefore, this experimental study analyses different combinations of influencing factors with respect to process forces, workpiece surface temperatures at the wire entrance, and the surface quality in wire sawing unidirectional CFRP material. As main influencing factors, the cutting and feed speeds, the density of diamond grains on the wire, the workpiece thickness, and the fibre orientation of the CFRP material are analysed and discussed. For the tested parameter settings, it is found that while the influence of the grain density is negligible, workpiece thickness, cutting and feed speeds affect the process substantially. In addition, higher process forces and workpiece surface temperatures do not necessarily deteriorate the surface quality.

特别是在切割硬脆材料时，广泛使用电镀金刚石线的线锯，因为它结合了高表面质量和最小切缝损失。此外，它还可以通过同时加工多个工件实现高生产率。在加工操作期间，线材/工件相互作用以及由此产生的工件质量的材料去除条件由材料特性以及工艺和刀具参数决定。然而，应用于碳纤维增强聚合物 (CFRP) 的加工，由于材料的各向异性、材料的弹性回弹潜力以及由于高磨损碳纤维造成的明显机械磨损，工艺复杂性可能会增加。所以，本实验研究分析了加工力、线入口处工件表面温度和线锯单向 CFRP 材料的表面质量等影响因素的不同组合。对切​​削进给速度、丝上金刚石晶粒密度、工件厚度、CFRP材料的纤维取向等主要影响因素进行了分析和讨论。对于测试的参数设置，发现虽然晶粒密度的影响可以忽略不计，但工件厚度、切削和进给速度对工艺影响很大。此外，更高的加工力和工件表面温度不一定会降低表面质量。以及线锯单向CFRP材料的表面质量。作为主要影响因素，对CFRP材料的切削进给速度、金刚石晶粒密度、工件厚度、纤维取向等主要影响因素进行了分析和讨论。对于测试的参数设置，发现虽然晶粒密度的影响可以忽略不计，但工件厚度、切削和进给速度对工艺影响很大。此外，更高的加工力和工件表面温度不一定会降低表面质量。以及线锯单向CFRP材料的表面质量。对切​​削进给速度、丝上金刚石晶粒密度、工件厚度、CFRP材料的纤维取向等主要影响因素进行了分析和讨论。对于测试的参数设置，发现虽然晶粒密度的影响可以忽略不计，但工件厚度、切削和进给速度对工艺影响很大。此外，更高的加工力和工件表面温度不一定会降低表面质量。结果表明，虽然晶粒密度的影响可以忽略不计，但工件厚度、切削和进给速度对工艺有很大影响。此外，更高的加工力和工件表面温度不一定会降低表面质量。结果表明，虽然晶粒密度的影响可以忽略不计，但工件厚度、切削和进给速度对工艺有很大影响。此外，更高的加工力和工件表面温度不一定会降低表面质量。
