车削辅助表面冷成形（TASCF）是一种新发展的制造工艺，旨在同时加工和提高零件的表面质量/机械性能。尽管新的混合工艺显著降低了制造成本并提高了生产率，但混合工具的设计仍然取决于应用类型，并且必须考虑到“融合”工艺的技术需求。本文提出了在采用这种新工艺时需要考虑的一些关键标准，即：工具设计；工艺参数设置。在明确了TASCF的技术要求之后，通过改进的功能和混合工艺的操作约束之间的反复“协商”，通过“融合”车削和表面冷成形系统获得了优化的工具设计。进一步的设计评估包括TASCF工件约束、表面冷成形力的控制以及加工表面的几何精度。本文还介绍了一种用于检查和设计混合TASCF工具的流程图方法。按照所描述的方法，大多数类型的车削工具都可以针对TASCF进行重新设计，以使其能够在需要高精度和表面质量的部件以提高生产率的生产线中实施。
Turning assisted with superficial cold forming (TASCF) is a newly developed manufacturing process directed to simultaneously machine and enhance surface quality/mechanical properties of the components. Although the new hybrid process offers significant manufacturing cost reductions and productivity improvements, still the design of the hybrid tool depends on the application type and has to take into account the technological needs of the ‘fused’ processes. The paper flags-up some key criteria to be taken into account when employing this novel process, namely: tool design; setup of process parameters. After specifying the technical requirements of TASCF, through iterative ‘negotiations’ between improved functions and operation constraints of the hybrid process, an optimised tool design of was obtained by ‘fusing’ turning and superficial cold forming systems. Further design evaluation was also carried which includes TASCF workpiece constraints, control of surface cold forming force as well as geometrical accuracy of machined surfaces. A flowchart methodology to check and design hybrid TASCF tools for other applications has also been presented. Following the described methodology most types of the turning tools can be redesigned for TASCF to enable its implementation within production lines where high precision and surface quality of components are required at enhanced productivity rates.
